Description

Configuration method and device of optical transmission equipment and electronic equipment

Technical Field

The present invention relates to the field of optical transmission technologies, and in particular, to a configuration method and apparatus for an optical transmission device, and an electronic device.

Background

With the development of cloud computing, data centers carry most of the traffic of the internet, and the bandwidth of infrastructure networks grows exponentially. On the other hand, infrastructure networks are also rapidly expanding to edge scenes, and the size and the number of the infrastructure networks are further exploded. The optical transmission equipment provides an underlying interconnection channel between data centers, and the size of bandwidth and coverage carried by the optical transmission equipment is increased remarkably and synchronously.

In data center optical networks, the total amount of transmission equipment has risen dramatically. In the equipment opening construction stage, the traditional manual mode does not meet the requirements in the aspects of accuracy and timeliness. The demand for the automatic configuration of the optical transmission equipment is demanded in the face of a large number of repeated construction contents.

Various current automatic configuration schemes generally adopt a centralized configuration issuing mode, namely that an automatic configuration center exists at a far end (non-local), parameters are assigned according to a standardized mode, a configuration template is formed by combining the parameters, and the parameters are issued to equipment according to a specific sequence. This way of separating the configuration center from the equipment presents the following problems: 1) Because the configuration center and the equipment are not in the same place and are connected through the management network, the configuration issuing process is influenced by the management network, and the automatic configuration can be directly failed due to the fact that the management network is disconnected or faults occur; 2) When a transmission network is newly built, a management network is not provided, so that automatic configuration issuing based on a configuration center cannot be performed; 3) Various parameter values of the configuration center are mostly pre-cured, and parameters (such as optical cable length and loss) strongly related to the field environment are generally not in the configuration range; 4) The automatic configuration issuing process and the equipment physical connection process are separated, the automatic configuration is not triggered immediately after general physical connection is completed, and when the connection is wrong and the service is not available, effective feedback cannot be obtained in a short time, so that the repair and service opening time is prolonged.

In order to solve the technical problem that the efficiency of automatic configuration is low due to the fact that automatic configuration is carried out on optical transmission equipment by issuing a standard template in the related art, an effective solution is not provided at present.

In the above operating environment, the present application provides a configuration method of an optical transmission apparatus as shown in fig. 2. Fig. 2 is a flowchart of a configuration method of an optical transmission device according to a first embodiment of the present invention.

Step S201, when a configuration signal for indicating to configure the optical transmission device is detected, performing initial configuration on a target parameter of the optical transmission device.

Specifically, the configuration of the optical transmission device is started, that is, the configuration signal for instructing to configure the optical transmission device is detected, and the configuration signal may be triggered by default after the optical transmission device is powered on, or triggered by a button on a panel of the optical transmission device, or triggered based on a software command. After triggering the configuration signal, the light transmission device panel may be displayed by illuminating the associated status indicator light.

And after the configuration signal is detected, performing initial configuration on target parameters of the optical transmission equipment. For optical layer devices in the optical transmission device, the target parameters include, but are not limited to, an EDFA (erbium doped fiber amplifier) gain value, a VOA value, and the like, wherein the EDFA gain value may be configured to be a minimum value, and the VOA value may be configured to be the same as the EDFA gain, so as to avoid a power saturation phenomenon occurring when a link in the optical transmission device is just turned on.

For the electrical layer device of the optical transmission device, the target parameters include, but are not limited to, the light emitting power of OT (corresponding to a photoelectric converter in the electrical layer device), the modulation format of OT, and the like, wherein the light emitting power of OT can be configured to be a small value, and the OT modulation format can be configured to be a low modulation order, so as to ensure that the performance margin requirement of the optical transmission device is met.

Generally, when the optical transmission device is turned on for the first time, initialization configuration is performed according to default parameters, and if the optical transmission device has already performed parameter initialization configuration, the current parameter configuration can be kept unchanged, and connectivity verification is directly performed.

Step S202, when detecting that the target parameter initialization configuration of the optical transmission equipment is completed, executing connectivity verification on the optical transmission equipment to obtain a target verification result.

Specifically, connectivity verification is performed on connections among various devices or inside various devices in the optical transmission device to obtain a target verification result.

Step S203, if the target verification result is pass, optimizing the target parameter of the optical transmission device to complete the configuration of the optical transmission device.

Specifically, after the connectivity verification result passes, information such as the transmitting/receiving optical power, the error rate, and the optical path loss value of each device is obtained through a connection channel between each device in the optical transmission device, and parameters such as a BA gain value, a PA post-VOA value, an OT light emitting power, and an OT modulation format in the optical transmission device are optimized according to the information such as the transmitting/receiving optical power, the error rate, and the optical path loss, so as to improve the performance or the transmission capacity of the optical transmission device.

In summary, the optical transmission device performs configuration automatically, including initialization configuration of target parameters, connectivity detection and optimization of target parameters of the optical transmission device, without configuring the optical transmission device by using an automated configuration center in a manner of issuing a standard template, thereby improving the efficiency of automated configuration.

In an optional embodiment, the optical transmission device may include a first optical line termination device and a second optical line termination device, and then performing connectivity verification on the optical transmission device mainly includes the following three aspects: starting communication channels of a first optical line terminal device and a second optical line terminal device; performing connectivity verification on connection between first stations to obtain a first verification result, wherein the connection between the first stations represents connection between first optical line terminal equipment and second optical line terminal equipment, the first optical line terminal equipment consists of first electrical layer equipment and first optical layer equipment, and the second optical line terminal equipment consists of second electrical layer equipment and second optical layer equipment; performing connectivity verification on the intra-station connection to obtain a second verification result, wherein the intra-station connection represents the connection between the first electrical layer device and the first optical layer device and the connection between the second electrical layer device and the second optical layer device; performing connectivity verification on the optical channel connection to obtain a third verification result, wherein the optical channel connection represents the connection between the first electrical layer equipment and the second electrical layer equipment; and determining a target verification result according to the first verification result, the second verification result and the third verification result.

In an alternative embodiment, a typical unidirectional single-span optical transmission link model (i.e. the optical transmission apparatus described above) is shown in fig. 3, where the single-span optical transmission apparatus includes two OLT sites (i.e. the first optical line termination apparatus and the second optical line termination apparatus described above). The OLT station consists of electrical layer equipment and optical layer equipment. Electrical layer devices consist of a plurality of OT (optical to electrical converters) and optical layer devices typically consist of Mux/Demux, BA/PA, VOA, etc. devices. The two sites OLT are a local site and a remote site. The solid lines in fig. 3 represent the connections through which the light paths pass.

For the single-span optical transmission device, after the single-span optical transmission device starts connectivity verification, the related communication channels (i.e. the communication channels of the first optical line terminal device and the second optical line terminal device) are opened, and the connectivity verification mainly aims at the following 3 layers: inter-station connections (i.e. the first inter-station connections described above), intra-station connections and OCH connections (i.e. the optical channel connections described above). The first inter-site connection represents the connection between two OLT sites, the intra-site connection represents the communication between the electrical and optical layer equipment in each OLT site, and the OCH connection represents the communication between the OTs in the two OLT sites, as shown in fig. 4. The dotted line represents a communication channel between the electrical layer device and the optical layer device, when the electrical layer device and the optical layer device are in the same machine frame in the form of board cards, communication is generally directly performed based on a backboard, and when the electrical layer device and the optical layer device are not in the same machine frame, communication is generally performed based on a network cable.

In an alternative embodiment, a schematic diagram of a connectivity verification range between various devices in an optical transmission device is shown in fig. 5. Each device only needs to acquire the information of the directly connected device, and generally does not need to acquire the information of other devices on the whole link. For example, when the OLT site is used as the current device, information interaction is performed based on inter-station connection and an opposite-end direct-connected OLA site (that is, connectivity verification is performed on the inter-station connection), and information interaction is performed based on intra-station connection and all direct-connected OTs.

When OT is taken as the current equipment, the two situations are divided into 1) information interaction (namely, checking connectivity of OCH) is carried out on the basis of a GCC channel of electrical layer equipment and OT equipment directly connected to an opposite end, and 2) information interaction is carried out on the basis of interstation connection and OT equipment of the opposite end by means of optical layer equipment, and under the situation, a communication channel is established by the intrastation connection and the interstation connection of each optical layer equipment together, so that the information interaction between the OT equipment at the two ends is ensured.

Through the optical transmission equipment, central control equipment is not needed, each equipment can independently or parallelly start connectivity verification, and connectivity verification on inter-station connection, intra-station connection and OCH connection can also be independently or parallelly initiated, but generally, the connectivity verification on the OCH connection needs to be completed in advance.

In an optional implementation, if the connectivity problem of the optical transmission device is completely covered by the inter-station connection and the intra-station connection according to the actual situation, in order to simplify the step of the automatic configuration, the connectivity verification of the OCH connection may not be performed, so that the efficiency of the automatic configuration may be further improved.

The information interaction among various devices in the optical transmission equipment is ensured through the connectivity verification of the first in-station connection, the in-station connection and the OCH connection, so that an interconnection channel is provided for data centers through the optical transmission equipment, and the accuracy of automatic configuration of the optical transmission equipment is improved.

In an optional embodiment, the optical transmission device may include a first optical line termination device, a second optical line termination device, and at least one optical line amplifier device, and then performing connectivity verification on the optical transmission device mainly includes the following three aspects: starting communication channels of a first optical line terminal device, a second optical line terminal device and an optical line amplifier device; performing connectivity verification on connection between second stations to obtain a fourth verification result, wherein the connection between the second stations represents connection between the first optical line terminal device and the optical line amplifier device, the connection between the second optical line terminal device and the optical line amplifier device and the connection between the optical line amplifier device and the optical line amplifier device, and the optical line amplifier device comprises a third optical layer device; performing connectivity verification on the intra-station connection to obtain a fifth verification result; performing connectivity verification on the optical channel connection to obtain a sixth verification result; and determining a target verification result according to the fourth verification result, the fifth verification result and the sixth verification result.

In an alternative embodiment, a typical unidirectional multi-span optical transmission link model (i.e., the optical transmission apparatus described above) is shown in fig. 6, and the number of OLA sites (i.e., the optical line amplifier apparatus described above) is increased compared to the typical unidirectional single-span optical transmission link model. When the OLT station is used as the local station, the remote station is an OLA station; when the OLA site is used as the local site, the OLT sites at both ends are the upstream remote site and the downstream remote site, respectively.

For the multi-span optical transmission device, after the multi-span optical transmission device starts connectivity verification, the related communication channels (i.e. the communication channels of the first optical line terminal device, the second optical line terminal device, and the optical line amplifier device) are opened. The connectivity check mainly aims at the following 3 layers: inter-station connections (i.e. the second inter-station connections described above), intra-station connections and OCH connections (i.e. the optical channel connections described above). The second inter-station connection represents a connection between the OLT site and the OLA site, or a connection between the OLA site and the OLA site, the intra-station connection represents communication between electrical layer devices and optical layer devices in each OLT site, and the OCH connection represents communication between OTs in two OLT sites, as shown in fig. 7.

In an alternative embodiment, as shown in fig. 8, a schematic diagram of a connectivity verification range between various devices in an optical transmission device, each device only needs to acquire information of a directly connected device, and generally does not need to acquire information of other devices on the entire link. For example, when an OLT site is used as current equipment, information interaction is performed based on inter-site connection and an opposite-end direct-connected OLT site or an OLA site, and information interaction is performed based on intra-site connection and all direct-connected OT equipment;

when the OLA site is taken as the current equipment, information interaction is carried out based on inter-site connection, an upstream direct-connected OLA site or an OLT site and a downstream direct-connected OLA site or an OLT site;

when OT is taken as the current equipment, the method is divided into two situations, namely 1) information interaction is carried out on a GCC channel based on electrical layer equipment and OT equipment directly connected to the opposite end; 2) Information interaction is performed by means of the inter-station connection of the optical layer devices and the OT devices of the opposite ends, under the condition, it is ensured that the intra-station connection and the inter-station connection of each optical layer device are in a normal working state, and it is ensured that the OT devices of the two ends can perform information interaction through the optical layer devices, that is, an optical monitoring channel between the optical layer devices is used as an out-of-band channel of the electrical layer devices to perform connectivity verification of optical channel connection.

In order to improve the accuracy of performing connectivity verification on the connection between the stations, the following modes are adopted to perform the connectivity verification on the connection between the stations: starting optical monitoring channels of all optical layer equipment in first optical line terminal equipment and second optical line terminal equipment; continuously sending a first handshake message and detecting a second handshake message sent by optical layer equipment which is not the equipment through an optical monitoring channel; if the optical monitoring channel periodically detects the second handshake message and the light receiving power of the optical monitoring channel meets a first preset requirement, communicating with the optical layer device of the non-local device by adopting a first preset protocol; and if the first protocol interactive content of the optical layer equipment which is not the equipment is acquired, the connectivity verification representing the connection between the stations passes.

In an alternative embodiment, the single span optical transmission device comprises two OLT sites (i.e. the first optical line termination device and the second optical line termination device described above). The connectivity verification of the interstation connection for the single-span optical transmission equipment comprises the following steps:

starting Optical Supervisory Channels (OSCs) of all optical layer devices in two OLT sites, continuously sending Hello handshake messages (i.e. the first handshake message) through the OSCs, and continuously detecting Hello handshake messages (i.e. the second handshake message) sent by non-local sites, from the perspective of a first optical line terminal device, sending Hello handshake messages through the OSC of the first optical layer device of the first optical line terminal device, and detecting Hello handshake messages sent through the OSC of the second optical layer device of the second optical line terminal device;

if the OSC of the first optical layer device detects the second handshake message stably at a certain time and the reception optical power of the OSC is stable (i.e., the OSC meets the first preset requirement), performing information interaction with the remote device (i.e., the second optical line terminal device) through the LLDP protocol (i.e., the first preset protocol), otherwise, returning to the step of determining whether the Hello message is stably received;

if the protocol interactive content (i.e. the first protocol interactive content) is obtained through the LLDP protocol, for example, the protocol interactive content includes information such as device unique identification information, device type (OLT/OLA, etc.), component configuration (EDFA gain, VOA value), upstream and downstream connectivity states, it is considered that the connectivity check on the inter-station connection is passed, otherwise, the steps of determining whether the Hello packet is stably received and determining whether the optical power is stable are returned.

In order to improve the transmission efficiency of the optical transmission device, the target parameters of the optical transmission device are modified in the following way: calculating to obtain an optical cable loss value according to the receiving and transmitting optical power of the first optical layer equipment and the receiving and transmitting optical power of the second optical layer equipment; and setting target parameters of the optical transmission equipment according to the optical cable loss value.

After the connectivity check of the inter-station connection is confirmed, calculating an optical cable loss value of the optical cable based on the remote OSC transmit-receive optical power (e.g., the OSC of the second optical line terminal device) and the local OSC transmit-receive optical power (e.g., the OSC of the first optical line terminal device), taking the single-span optical transmission device as an example, further configuring PA gain and BA post-VOA value based on the optical cable loss value, wherein the overall principle is to adjust PA gain to completely compensate for the loss of the optical cable, the VOA value is default to 0, when the maximum PA gain is smaller than the optical cable loss value, adjust PA gain to the maximum PA gain, when the minimum PA gain is larger than the optical cable loss value, adjust PA gain to the minimum value, and adjust the VOA value so that the sum of the VOA and the optical cable loss is the same as the minimum PA gain.

In an optional embodiment, the interactive content of the first protocol is periodically refreshed, the EDFA gain and the VOA value are modified in real time based on the change of the bidirectional loss value of the optical cable, and the EDFA gain and the VOA value are not automatically modified any more after the optical transmission equipment exits from the self-driven configuration mode.

Through the steps, the parameters of the optical transmission equipment are adjusted according to the loss value of the optical cable, and the problems of improving the transmission efficiency of the optical transmission equipment and reducing the transmission loss are solved.

In an alternative embodiment, the multi-span optical transmission device includes two OLT sites and an OLA site, that is, includes a first optical line termination device, a second optical line termination device, and an optical line amplifier device. Taking the intra-station connection between the first optical line termination device and the optical line amplifier device as an example, the connectivity verification for the inter-station connection of the optical transmission device includes:

starting Optical Supervisory Channels (OSCs) of all optical layer devices in a first optical line terminal device and an optical line amplifier device, and continuously sending Hello handshake messages (i.e. the first handshake messages) through the OSC, and continuously detecting Hello handshake messages sent by non-local stations (i.e. the second handshake messages), from the perspective of the first optical line terminal device, sending Hello handshake messages through the OSC of the first optical layer device of the first optical line terminal device, and detecting Hello handshake messages sent through the OSC of the optical layer device in the optical line amplifier device;

if the OSC of the first optical layer device stably detects the second handshake message at a certain time and the optical reception power of the OSC is stable (i.e., the OSC meets the first preset requirement), interacting with the remote device (i.e., the optical line amplifier device) through the LLDP protocol (i.e., the first preset protocol), otherwise, returning to the step of determining whether the Hello message is stably received;

if the protocol interaction content (i.e., the first protocol interaction content) is stably acquired, for example, the protocol interaction content includes information such as device unique identification information, device type (OLT/OLA, etc.), component configuration (EDFA gain, VOA value), upstream and downstream connectivity states, it is considered that the connectivity check on the inter-station connection is passed, otherwise, the steps of determining whether the Hello packet is stably detected and determining whether the optical power is stable are returned.

In an alternative embodiment, the connectivity verification of the inter-station connection may be performed according to the flowchart of the connectivity verification of the inter-station connection shown in fig. 9.

Through the steps, accurate verification of connection between stations can be achieved, and when a fault occurs, alarm processing is carried out so as to rapidly process the fault.

In order to improve the transmission efficiency and the transmission bandwidth of the optical transmission equipment, after the target verification result is passed, the following steps are adopted to optimize the parameters of the optical transmission equipment: acquiring the sum of the luminous power of all photoelectric converters of all electrical layer equipment in first optical line terminal equipment and second optical line terminal equipment to obtain total luminous power; acquiring the light receiving power of a preamplifier of optical layer equipment of first optical line terminal equipment, and calculating to obtain a third insertion loss value of the light receiving power and the total luminous power of the preamplifier; if the third insertion loss value is not in a third preset range, adjusting the gain of the preamplifier or the luminous power of the photoelectric converter so as to enable the third insertion loss value to be in the third preset range; if the luminous power of all the photoelectric converters is not within a fourth preset range, optimizing adjustable optical attenuator values of optical layer equipment in the first optical line terminal equipment and the second optical line terminal equipment so as to enable the luminous power of all the photoelectric converters to be within the fourth preset range; acquiring pre-correction error rates of all photoelectric converters and optical cable loss values of interstation connections; judging the performance allowance of an optical channel of the optical transmission equipment according to the error rate before correction and the optical cable loss value; and if the performance margin is not in the fifth preset range, modifying the modulation formats of all the photoelectric converters so as to enable the performance margin to be in the fifth preset range.

Specifically, parameters such as BA gain, PA post-VOA value, OT light emitting power, OT modulation format, and the like are modified based on information such as transmitted and received optical power, bit error rate, optical path loss value, and the like of the local device and the remote device OT, so as to optimize the OCH performance or improve the transmission capacity of the optical transmission device.

in an alternative embodiment, the gain of the optical transmission device may also be adjusted by the luminous power of a single OT.

and judging the OCH performance margin based on the OT error rate before correction or the optical cable loss value, and providing a larger transmission bandwidth while the OCH has enough performance margin by modifying the OT modulation format.
