The following will describe in detail the method and apparatus for configuring optical network wavelength division devices, electronic devices, and storage media provided in the embodiments of the present application.

Referring first to fig. 1, fig. 1 is a schematic diagram of an implementation environment according to the present application. The implementation environment is an optical network system, and the optical network system includes a first electrical layer device 100 that emits service light, an optical layer device 200 that transmits service light, and a second electrical layer device 300, where the first electrical layer device 100 can further perform electro-optical conversion, emit service light through an optical module laser and send the service light to the optical layer device 200, and perform service light transmission through the optical layer device 200, and then the service light performs downlink, where service light with different wavelengths reaches the second electrical layer device 300 to perform photoelectric conversion, and finally output to an interface corresponding to the service to complete service scheduling.

The first electrical layer device 100 and the second electrical layer device 300 are client side devices, and can support electrical layer boards of 400G TMUX, 200G TMUX-1, 200G TMUX-2 and other types, and different types of electrical layer boards support access of different types of interfaces, for example, 400G TMUX supports access of 4x100GE, 100GE FlexE, OTU4 and the like, and the line side transmission capacity (i.e., the service type of an optical module of the first electrical layer device) is 4x22dB (4 is a span in the optical layer device, and 22dB is a maximum allowable attenuation value between spans); 200G TMUX-1 supports access of 2x100GE, 100GE FlexE, OTU4 or 100G+10G (STM 64, 10GE, OTU2, 10 GE-WAN) and the like, and the transmission capacity of the line side is 8x22dB (200G 16 QAM), 18x22dB (200G QPSK); 200G TMUX-2 supports access of 2x100GE, 100GE FlexE, OTU4 and the like, and the transmission capacity of the line side is 8x22dB (200G 16 QAM) and 18x22dB (200G QPSK).

The optical layer device 200 is a line-side device, and is responsible for amplifying, combining and splitting, where the optical layer device 200 includes a plurality of nodes, where service optical transmission can be performed between the nodes, and each node can perform uplink and downlink, where each node is configured with related devices, such as OPA (Optical Preamplifier Amplifier, optical preamplifier), OBA (Optical Booster Amplifier, optical power amplifier), WSS (Wavelength Selective Switch ), VOA (Variable Optical Attenuator, variable optical attenuator), OMU (wavelength division multiplexing device combiner, optical Multiplex Unit) ODU (Optix Division Unit, wavelength division multiplexing device demultiplexer), and the like. Wherein, the gain range of the OBA board card is 8-18 dB, and the gain range of the OPA board card is 15-25 dB; the WSS board card supports 5-dimensional WSS and 9-dimensional WSS, and the channel spectrum width is 100GHz; the OMU board card/ODU board card supports 48-wave up/down waves, and the channel spectrum is 100GHz wide.

It will be appreciated that only one first electrical layer device 100, optical layer device 200, and second electrical layer device 300 are shown in fig. 1, and that in other embodiments the number of first electrical layer devices 100, optical layer devices 200, and second electrical layer devices 300 may be plural, without limitation.

Specifically, the optical layer device 200 may be a single span scene (two nodes) or a short-distance multi-span scene (multiple nodes, N nodes may have N spans, where the number of spans may be determined by the type of a board sending service light in the first electrical layer device 100, if there are 9 nodes, the first node is span 1, the second node to the third node are span 2, and so on, the 8 th node to the 9 th node are spans 9), the first node in the optical layer device 200, i.e. the node receiving the service light sent by the first electrical layer device 100, is called an originating node, the originating node includes OMU, OBA, and OMU for performing a multiplexing process on the service light with multiple different wavelengths sent by the first electrical layer device 100, and then performing an optical power amplification on the multiplexed wave through the OBA, and sending the multiplexed wave to the next node, where, of course, the originating node may be an up wave or a down wave, and if other service light is performed on the originating node or each of the originating nodes in the second electrical layer device 300 needs to be a preset service wave, and therefore the WSS may be further understood by a graph or a certain number of wave may be further understood when the WSS is a corresponding to be drawn on the originating node or a certain service wave.

For the last node in the optical layer device 200, the final node is set as a final node, and the final node is used for splitting the service light and sending the service light to the plurality of second electrical layer devices 300 respectively, the final node includes an OPA and an ODU, the OPA amplifies the optical power of the service light sent by the previous node, the service light received by the ODU is split into service lights with different wavelengths, and then each service light can reach different second electrical layer devices 300, of course, the final node may also be up-wave or down-wave, so a WSS is preset in the final node, and only one WSS is drawn in fig. 1 for combining or splitting the service light through the WSS when the final node up-wave or down-wave, which should be understood that other numbers can be also be provided, and each WSS can have a VOA built in to adjust the in-fiber optical power of the span.

When there are multiple spans in the optical layer device 200, there are multiple intermediate nodes between the start node and the end node, where the intermediate nodes include OPA, OBA, WSS, and for the intermediate nodes, there must be uplink waves and downlink waves of the traffic light in the traffic light transmission process, so WSSs need to be set in the intermediate nodes, and of course, two WSSs of the intermediate nodes are shown in fig. 1 by way of example, and it should be understood that in other embodiments, there may be other numbers of WSSs, which are not limited herein. Similarly, the OPA in the intermediate node performs power amplification, that is, pre-amplification, on the traffic light transmitted by the previous node, and the OBA performs optical power amplifier transmission on the traffic light to the next node. For the OPA board and the OBA board in the optical layer device 200, the OPA board and the OBA board of each node may be a front VOA, which is not shown in fig. 1, and is used for adjusting the span loss of the span of the node, so that the span loss is within a certain range, and the front VOA of the OBA board is used for adjusting the optical power of the service light input into the OBA.

In one embodiment, the optical layer device 200 in fig. 1 may be configured so that the first electrical layer device 100, the optical layer device 200, and the second electrical layer device 300 may be electrically decoupled, i.e., support heterogeneous networking of the optical layer device and the electrical layer device.

Specifically, the optical layer device 200 accesses service light at the starting node, confirms that the optical power of the output port of the OMU single board is confirmed to be correct, and the optical power of the output port of the OMU is transmitted through a preset WSS board card in the starting node, if the starting node does not have the preset WSS board card, the optical power is directly transmitted to the OBA of the starting node, in order to ensure the flatness, the optical power of the service output by the first electrical layer device to the starting node is controlled by adjusting the optical power output by a light modulation module laser on the first electrical layer device, so that the average single wave power of the optical power output by the OBA of the starting node does not exceed a preset power threshold, and the power threshold can be determined according to the service type of an optical module of the electrical layer device, for example, when the service type of the optical module of the electrical layer device is 200G 16QAM (16 QAM is a modulation mode under 200G line), the preset threshold is +1dbm; when the service type is 200G QPSK, the preset threshold is +2.5dBm; when the service type is 400G16QAM, the preset threshold is +3dBm.

Then, the service light reaches the next node through the OBA of the starting node, and at this time, by controlling the pre-VOA of the next node OPA, the span loss between the starting node and the next node is not lower than a preset span loss threshold, and the next node of the starting node can be a terminal node or an intermediate node. Of course, for spans between subsequent nodes of the starting node, the pre-VOA of the OPA in the subsequent node in the span needs to be controlled so that the span loss of the span is not lower than a preset span loss threshold.

If an intermediate node exists between the initial node and the final node, the OPA output optical power and the OBA input optical power of the intermediate node are detected, the node internal attenuation of the intermediate node is determined, if the node internal attenuation is lower than a preset internal attenuation threshold, the node internal attenuation in the intermediate node is not lower than the preset internal attenuation threshold by adjusting the front VOA of the intermediate node, and therefore, the intermediate node needs to control the front VOA of the corresponding intermediate node to ensure that the cross loss between the intermediate node and the previous node is not lower than the preset cross loss threshold and the node internal attenuation in the intermediate node is not lower than the preset internal attenuation threshold in the service optical transmission process.

When there is an intermediate node, for the span in the optical layer device 200, the fiber-in optical power in the span may be adjusted so that the average single-wave power of the OBA output optical power of the previous node does not exceed the preset threshold, specifically, for a certain span a, the span a is the span from the nth node to the (n+1) th node, by adjusting the built-in VOA of the WSS module located before the OBA in the (n+1) th node, so that the average single-wave power of the OBA output optical power of the (n-1) th node does not exceed the preset threshold, and adjusting the built-in VOA of the WSS does not affect the intra-node attenuation of the node.

Of course, in this embodiment, the input port of the OBA may also be adjusted, and specifically, the average single wave power of the input optical power of the OBA of the node may be adjusted by adjusting the pre-OBA VOA or the previous WSS of the OBA in the node so that the average single wave power of the input optical power of the node OBA does not exceed a preset threshold. For the optical layer apparatus 200, at the start node or the first two nodes of the optical layer apparatus, there are fewer waves in the nodes as a whole, that is, the service optical power reaching the OBAs of these nodes meets the requirement of the input interface of the OBA, the input ports of the OBAs of the start node or the first two nodes may not be adjusted, for example, the input ports of the OBAs of the 3 rd node and the following nodes may be adjusted from the 3 rd node.

Meanwhile, for the OPA in the node, when the node of the optical layer device 200 is more backward, the service optical power received by the OPA of the following node will be greater due to the uplink and downlink in the preceding node, so as to affect the transmission of the service light in the optical layer device, based on this, the output optical signal to noise ratio of the OPA in the node is also detected, when the optical signal to noise ratio is lower than the preset signal to noise ratio threshold, the WSS in the preceding node of the node is controlled to perform the downlink to the local wave decomposition, otherwise, the node is thorough. Of course, in the same way, in the starting node or the first two nodes of the optical layer device, if there are fewer total waves in the node, the output osnr of the OPA of the starting node or the first two nodes may not be detected, for example, from the 3 rd node, the output osnr of the OPA in the node may be detected, and whether to download is determined.

By amplifying, wave combining, wave dividing and other processes of each node in the optical layer equipment, the service light finally reaches the final node, namely the last node, the transmission capacity of the final node reaches the limit, at the moment, the error rate before correction of all the service light needing to be subjected to wave down after ODU division can be verified, whether the transmission meets the condition of normal transmission or not is verified, and the service light with different wavelengths is distributed to different second electric layer equipment after the ODU wave down is configured at the final node.

The configuration method of the optical network wavelength division equipment provided in the embodiment supports the heterogeneous networking of optical layer equipment and electrical layer equipment, realizes the photoelectric open decoupling of the equipment, and can also uniformly and automatically configure the equipment of a plurality of companies to realize the uniform nano-tube of the network management. Meanwhile, the method is applicable to the scene of large-bandwidth point-to-point service scheduling, and has high adaptation degree and high reliability with a machine room.

Fig. 2 is a flow chart illustrating a method of configuring an optical network wavelength division device according to an exemplary embodiment. The method for configuring an optical network wavelength division device may be applied to the implementation environment shown in fig. 1 and specifically executed by an optical network system in the implementation environment, and it should be understood that the method may also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments, and the embodiment is not limited to the implementation environment to which the method is applied.

As shown in fig. 2, in an exemplary embodiment, the method may include steps S210 to S290, which are described in detail as follows:

step S210: and adjusting an optical module laser on the electric layer equipment to ensure that the output optical power of an OBA on a starting node receiving service light sent by the optical module laser does not exceed a preset power threshold.

In this embodiment, adjusting the optical module laser on the electrical layer device is adjusting the optical module laser on the first electrical layer device in fig. 1, that is, adjusting the optical module laser on the electrical layer device that emits the service light.

Specifically, the electric layer device sending out the service light outputs the service light through the optical module laser, the service light reaches the optical layer device, a starting node in the optical layer device is connected with the service light, the service light is confirmed by confirming the optical power of an OMU single board output port, a WSS (wireless sensor system) can be preset in the starting node, when the service light of other devices in the starting node goes up or down, the wave combination and the wave division can be carried out through the WSS, and at the moment, the optical power of the OMU output port is transmitted through the WSS board card.

In this embodiment, in order to ensure flatness, the OBA of the initial node uses a default gain, and controls the service light from the electrical layer device to the optical layer device by adjusting the output service light power of the optical module laser in the electrical layer device, so that the output light power of the initial node OBA does not exceed a preset power threshold.

The preset power threshold is related to the service type of the optical module in the electrical layer equipment, the service types of the optical module are different, the power threshold is set based on experience parameters under the service types of the different optical modules, and if the service type of the optical module is 200G 16QAM (16 QAM is a modulation mode under a 200G line), the preset threshold is +1dBm; when the optical module traffic type is 200G QPSK, then the preset threshold is +2.5dBm, which is, of course, merely exemplary, and in other embodiments, the power threshold may be other values.

Step S230: and controlling the input optical power and the output optical power of the OBA in the intermediate node not to exceed a preset power threshold.

In this embodiment, when service light sent by an OBA of an initial node arrives at a next node, that is, a plurality of intermediate nodes, the service light is transmitted according to the sequence of the intermediate nodes, and meanwhile, the intermediate nodes have the condition of up-wave or down-wave, and WSSs set in the intermediate nodes can be used for up-wave combination and down-wave splitting, and since the up-wave and down-wave of the intermediate nodes are frequent, a plurality of WSSs can be set in the intermediate nodes, such as 2 WSSs shown in fig. 1, and of course, other WSSs can be set in the intermediate nodes, which is not limited herein.

For the service light reaching the intermediate node, as with the initial node, there is also a power requirement for the OBA output line and the input line in the intermediate node, so that it is also necessary to control the input optical power and the output optical power of the OBA in the intermediate node not to exceed the preset power threshold.

The preset power threshold of the intermediate node is related to the output line/input line of the OBA, as is the preset power threshold in the initial node.

The output optical power of the intermediate node OBA is realized by controlling the fiber-in optical power of the next span. Specifically, for the output optical power control of the intermediate node n, the effect of controlling the fiber-entering optical power of the span is achieved by controlling the fiber-entering optical power of the span between the intermediate node n and the intermediate node n+1, that is, by controlling the built-in VOA of the WSS in the intermediate node n+1.

The aim of controlling the fiber-entering optical power of the span is achieved by controlling the built-in VOA of the WSS in the second node in the middle span, and because both nodes in the middle span are middle nodes, a plurality of WSSs can exist, at the moment, the aim of controlling the fiber-entering optical power of the span is achieved by controlling the WSS closest to the OBA in the middle node, namely the WSS positioned in front of the OBA in the middle node.

On the other hand, the control of the input optical power of the OBA in the intermediate node may be accomplished by the output of the WSS in the intermediate node and/or the pre-VOA of the OBA in the intermediate node.

Specifically, a pre-VOA may be set before the OBA of the intermediate node, and then the purpose of controlling the input optical power of the OBA in the intermediate node is achieved by controlling the pre-VOA, or the output of the WSS in the intermediate node may be controlled, so that the input optical power of the OBA in the intermediate node meets the requirement by controlling the output of the WSS.

Of course, when the number of WSSs in the intermediate node is plural, the previous WSS of the OBA in the intermediate node may be controlled.

Similarly, the preset power threshold in the intermediate node is the same as the power threshold set for the OBA in the starting node, that is, the preset power threshold in the intermediate node is related to the service type of the optical module in the electrical layer equipment sending out the service light, the service types of the optical module are different, and the corresponding power threshold is also different, if the service type of the optical module is 200G 16QAM (16 QAM is a modulation mode under 200G), the preset threshold is +1dbm; when the service type of the optical module is 200G QPSK, the preset threshold is +2.5dBm; when the service type of the optical module is 400G 16QAM, the preset threshold value is +3dBm.

Meanwhile, when the service light propagates in the optical layer device, the wave number on the first few nodes is limited, and the input optical power of the OBA reaching each node is limited, so that the control of the input optical power of the OBA in the intermediate nodes can be based on the experience parameters, the first few nodes of the intermediate nodes do not control the input optical power, such as the control of the input optical power is restarted from the second intermediate node, and the configuration workload is reduced.

Step S250: and adjusting the preposed VOA of the OPA in the intermediate nodes to ensure that the span loss of the corresponding span is not lower than a preset span loss threshold value, and ensuring that the node internal attenuation of each intermediate node is not lower than a preset internal attenuation threshold value.

In this embodiment, in order to ensure the transmission security and efficiency of the service light, it is also necessary to control the intra-node attenuation of the service light in the intermediate node to be within a required range, and the inter-span loss in the optical layer device to be within the required range.

The setting of the cross-loss threshold is related to the electrical layer device corresponding to the optical layer device, specifically, the line side transmission capability of the board card of the electrical layer device, if the line side transmission capability of the board card is 4x22dB when the board card is 400G TMUX, the cross-loss threshold is set to 22dB, and of course, different line side transmission capabilities correspond to different cross-loss thresholds, which is not limited specifically herein.

After the span loss threshold is determined, the span loss of the span in the optical layer equipment needs to be ensured not to be lower than the span loss threshold, and if the span loss is lower than 22dBm, the front-end VOA of the OPA board card of the node in the span is adjusted.

Specifically, for the second span, that is, the span from the initial node to the first intermediate node, the pre-VOA of the OPA of the first intermediate node is adjusted so that the span loss from the initial node to the span in the first intermediate node is not lower than a preset span loss threshold.

For the control of the intra-node attenuation of the intermediate node, this can be achieved by the difference between the output optical power of the OPA and the input optical power of the OBA in the intermediate node, and then adjusting the pre-VOA of the OPA corresponding to the intermediate node.

For the adjustment of the WSS of the intermediate node in step S230 so that the output optical power of the OBA does not exceed the power threshold, the adjustment of the built-in VOA in the WSS will not affect the intra-node attenuation of the node.

Step S270: and controlling the output optical signal to noise ratio of the OPA in the intermediate node not to be lower than a preset signal to noise ratio threshold.

The signal-to-noise ratio threshold in this embodiment may be determined based on empirical parameters.

Specifically, firstly detecting the output optical signal to noise ratio of OPA in an intermediate node; if the signal-to-noise ratio of the output light of the OPA in the intermediate node is lower than a preset signal-to-noise ratio threshold, the waves are locally decomposed based on the WSS in the last node of the intermediate node, and similarly, if the last node of the intermediate node of the OPA with the output light signal-to-noise ratio lower than the preset signal-to-noise ratio threshold is also the intermediate node, a plurality of WSSs are included in the intermediate node, and the first WSS in the intermediate node can perform the wave-down processing for distinguishing the WSSs controlling the input light power of the OBA.

And if the signal-to-noise ratio of the output light of the OPA in the intermediate node is not lower than a preset signal-to-noise ratio threshold, transmitting the service light based on the intermediate node.

Of course, in the first few nodes of the optical layer device, since there are fewer uplinks, the osnr of the OPA in the nodes should meet the threshold, so that the first few nodes may not perform osnr control based on the empirical parameters, for example, the output osnr of the OPA in the intermediate node may be detected from the 2 nd intermediate node, and the osnr control may be performed.

Step S290: the downwave is configured based on the end node.

In this way, the service light is transmitted based on the sequence of each node in the optical layer device, wherein the service light passes through the uplink and downlink of each node and the control mode in steps S210 to S270, finally reaches the terminal node, the transmission capability reaches the limit, the service light reaching the terminal node can be split through the ODU to obtain service light with different wavelengths, at this time, the error rates before correction of all the service lights with different wavelengths need to be verified, namely, the error rates before correction of the service lights with different wavelengths are verified, whether the service lights with different wavelengths are transmitted to meet the condition of normal transmission is determined, if so, the service light with different wavelengths can be configured to be transmitted through the ODU in the terminal node, so that the service light with different wavelengths can be obtained after the splitting is transmitted to the corresponding second electrical layer device through the ODU.

In a specific embodiment, if there are 9 nodes in the optical layer device, i.e. 9 spans, the initial node (node 1) is the first span, the nodes 1 to the first intermediate node (node 2) are the second spans, and so on, the nodes 8 to 9 are the ninth spans, and the specific steps when the configuration is performed based on the manner in fig. 2 are as follows: service light is accessed to the node 1, and the optical power confirmation of the output port of the OMU single board is confirmed without error; the optical power of the OMU output port is transmitted through the WSS board card; the OBA output optical power of the node 1 is adjusted, and in order to ensure flatness, the OBA of the node 1 uses default gain, and the OBA output optical power of the node 1 is enabled to be not more than +1dBm by the output optical power of the dimming module laser, and not more than +2.5dBm,400G 16QAM average single wave power is not more than +3dBm by 200G 16QAM average single wave power; the span loss requirement of the 1 st span is adjusted to be not lower than 22dB; and if the voltage is lower than 22dBm, adjusting the front VOA of the OPA board card.

Then adjusting the node internal attenuation of the node 2 to be not lower than 15dB, for example, the difference value between the output optical power of the OPA of the node 2 and the input optical power of the OBA can be read out through software, and then adjusting the front-end VOA of the OPA; the optical power of the fiber entering of the 2 nd span is adjusted, and the built-in VOA of the WSS module closest to the OBA of the node 2 is adjusted, so that the OBA of the node 1 outputs the optical power: the 200G 16QAM average single wave power is not more than +1dBm, the 200G QPSK average single wave power is not more than +2.5dBm,400G 16QAM average single wave power is not more than +3dBm.

Then, adjusting the span loss requirements of the spans 2, 3, 4, 5, 6, 7 and 8 to be not lower than 22dB, and if the span loss requirements are lower than 22dBm, adjusting the front VOA of the OPA board card; according to the arrival sequence of the service light, the node internal attenuation of the nodes 2, 3, 4, 5, 6, 7 and 8 is adjusted to be not lower than 15dB; and adjusting the optical power of the optical fibers of the 3 rd, 4 th, 5 th, 6 th, 7 th and 8 th spans to ensure that the OBA output optical power of the previous node is not more than +1dBm for 200G 16QAM average single wave power, and not more than +2.5dBm,400G 16QAM average single wave power and not more than +3dBm for 200G QPSK average single wave power. The built-in VOA of the 2 nd WSS module of the node 2 is adjusted, and the 15dB internal attenuation of the node 2 is not influenced; the output optical signal to noise ratio of OPA of nodes 3, 4, 5, 6, 7, 8 is tested if it is below 25dB. If <25dB, the WSS card 1 of the last node is used for down-wave to the local wave-decomposition. If the transmission power is more than or equal to 25dB, the transmission is transmitted at the node; the OBA input ports of the 3 rd, 4 th, 5 th, 6 th, 7 th and 8 th nodes are adjusted, so that the service optical power meets the requirements that the fiber-in power is 200G 16QAM average single-wave power is not more than +1dBm, the 200G QPSK average single-wave power is not more than +2.5dBm,400G 16QAM average single-wave power is not more than +3dBm; and each light needs to be flat as much as possible; and the 9 th node, the transmission capacity reaches the limit, verifies the error rate before correction of all the service lights of the downlink, verifies whether the transmission meets the condition of normal transmission or not, and configures the downlink through the ODU at the node.

By adjusting the fiber-entering optical power of the middle span, the output optical power of the OBA in the first node in the middle span does not exceed the power threshold, and the fiber-entering optical power of the middle span is adjusted by the built-in VOA of the WSS in another middle node except the first node in the middle span.

Similarly, another node different from the first node in the intermediate span is an intermediate node, and a plurality of WSSs may exist in the intermediate node, and at this time, the purpose of controlling the fiber-entering optical power of the span is achieved by controlling the WSS closest to the OBA in the other node, that is, the WSS located before the OBA in the other node.

step S510: a cross-loss between the intermediate spans is detected.

The intermediate spans include other spans of the plurality of nodes of the optical layer device except for the first span and the last span.

In this embodiment, the span loss of the intermediate span needs to be controlled not to be lower than the span loss threshold, and the setting of the span loss threshold is related to the electrical layer device corresponding to the optical layer device.

Step S530: and if the target span with the span loss lower than the span loss threshold exists, adjusting the preposed VOA of the OPA in the node corresponding to the target span.

If the span loss of a certain intermediate span is lower than the span loss threshold, the intermediate span includes two nodes, and most of the two nodes include spans respectively including OPA except the second span (the second span in the optical layer device is the span from the initial node to the first intermediate node, and the initial node has no OPA), so that the span loss of the intermediate span is not lower than the span loss threshold by adjusting the pre-VOA of the OPA in the second node in the intermediate span.

In this embodiment, it is required to control the signal-to-noise ratio of the output light of the OPA in the intermediate node to be lower than a preset signal-to-noise ratio threshold.

Step S730: if the signal to noise ratio of the output light of the OPA in the intermediate node is lower than the signal to noise ratio threshold, the WSS in the last node of the intermediate node is based on down-wave to local wave decomposition.

If the output optical signal-to-noise ratio of the OPA within the intermediate node is below the signal-to-noise ratio threshold, then a local solution may be downwave from the WSS of the node immediately preceding the intermediate node.

Of course, the initial node may not have a WSS, and the first few nodes in the optical layer device have fewer uplink waves, so that the control of the output optical signal-to-noise ratio of the OPA can be performed from the second intermediate node, i.e. the 3 rd node in the optical layer device.

Step S750: and if the signal to noise ratio of the output light of the OPA in the intermediate node is not lower than the signal to noise ratio threshold, transmitting the service light based on the intermediate node.

If the signal-to-noise ratio of the OPA output light in the intermediate node is not lower than the signal-to-noise ratio threshold, the OPA output in the intermediate node is proved to meet the requirement, and the traffic light is transmitted through based on the intermediate node.

The embodiment proposes to control the output optical signal to noise ratio of the OPA in the intermediate node so that the output of the OPA meets the requirement, thereby ensuring the performance of service optical transmission.
