Fig. 2 is a flowchart of a monitoring method of a spectrometer according to an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:
step S202, in response to a first trigger instruction, acquiring first optical power input by an input port of the optical splitter and second optical power output by an output port of the optical splitter by monitoring equipment;
step S204, the monitoring equipment determines the difference value between the acquired first optical power and the transmission loss power as a third optical power output by the optical splitter;
step S206, when the difference between the second optical power and the third optical power is smaller than the preset threshold, the monitoring device determines that the working state of the optical splitter is a normal state.
Through the steps, the optical power of the input port and the output port of the optical splitter can be automatically acquired through the monitoring equipment, the expected output optical power is calculated according to the optical power of the input port of the optical splitter, and finally the calculated expected output optical power is compared with the actually output optical power to determine that the expected output optical power is achieved, so that the purpose of monitoring the optical power of the optical splitter is achieved, the technical effect of automatic and accurate monitoring is achieved, and the technical problem of low working efficiency of monitoring the operation state of the optical splitter is solved.
It should be noted that the optical splitter is an important passive device in the optical fiber link, and is an optical fiber junction device having a plurality of input ends and output ends. Optical power losses occur when the fiber passes through the splitter.
In step S202, the first trigger instruction may be a switch on/off of the monitoring device, or a control instruction of the monitoring device interface, for example, a button for confirming the monitoring on.
In step S204, the third optical power is obtained by subtracting the transmission loss from the first optical power input through the input port of the optical splitter.
In step S206, when the difference between the second optical power and the third optical power is smaller than the preset threshold, it is determined that the optical power output by the optical splitter reaches the calculated expected output optical power, and then the working state of the optical splitter is determined to be a normal state.
It should be noted that, the working state of the optical splitter indicates normal, and the optical signal input to the optical splitter is divided into two links according to a preset ratio and output. In a practical application scenario, it can be used to indicate that there is no case of adding an optical splitting link privately.
The above steps S202 to S206 are described in detail by specific examples.
In response to the first trigger instruction in step S202, the monitoring device obtains a first optical power input by the input port of the optical splitter and a second optical power output by the output port of the optical splitter, and includes: the monitoring equipment determines the output optical power of network element ports on two sides of the optical splitter as a first optical power; the monitoring device determines the sum of the received optical power of the network element ports on both sides of the optical splitter and the received optical power of the optical splitting system as a second optical power, as shown in fig. 3, in the figure, the port a device port may be a network element port of an active device, and is physically connected to an optical fiber, and can report an optical power performance value and a port flow value. The optical splitter is a passive device in an optical fiber link, and is used for multiplexing an input optical signal into a plurality of output optical signals, wherein the intensity of the optical signals is influenced by the optical splitting ratio. The B-end equipment port is a network element port of active equipment, is physically connected with the optical fiber and can report an optical power performance value and a port flow value. The port of the optical splitting system is a network element port of an active device, for example: the switch and the convergence and shunt equipment are physically connected with the optical fiber and can report the optical power performance value and the port flow value. The monitoring equipment is connected with the A-end equipment, the B-end equipment and the light splitting system so as to obtain a port optical power performance value and a port flow value which are connected with the light splitter; and judging and monitoring the working state of the optical splitter, wherein network element ports connected with an input port of the optical splitter and an output port of the optical splitter are determined as ports on two sides of the optical splitter.
In step S204, the determining, by the monitoring device, the difference between the acquired first optical power and the transmission loss power as a third optical power output by the optical splitter includes: the monitoring equipment acquires transmission loss power, wherein the transmission loss power at least comprises: a first loss power and a second loss power, wherein the first loss power comprises an insertion loss power, and the second loss power comprises a bare fiber loss power; and the monitoring equipment subtracts the first loss power and the second loss power from the first optical power to obtain a third optical power.
It should be noted that in this application, the first optical power may be directly obtained through the network element ports of the device a and the device B, and the second optical power may be obtained by adding the received optical powers obtained through the network element ports of the device a and the device B and the network element port of the optical splitting system. The received light power calculation formula of the optical splitter is as follows: w 3 ＝W 1 -W s1 -W s2 Wherein, W 1 Denotes a first optical power, W 3 Denotes a third optical power, W s1 Denotes the first power loss, W s2 Representing the second power loss.
The additional loss is a decibel number of the light power of all output ports of the optical splitter relative to the input light power loss, and can be ignored when the devices at two ends of the optical splitter are deployed in the same target area, such as in the same communication building or the same local area network; the insertion loss is the ratio of the output optical power to the input optical power after passing through the optical splitter; bare fiber losses include fiber losses and active connector losses.
In an actual application scenario, before the monitoring device is started to monitor the optical splitter, the monitoring device identifies the corresponding relationship between the light-emitting optical fiber of the port of the a-side device and the input port of the optical splitter, the light-receiving optical fiber of the port of the B-side device and the output port of the optical splitter, and the corresponding relationship between the light-receiving port of the optical splitting system and the output port of the optical splitter according to the change condition of optical power. And synchronously identifying the corresponding relations between the light-emitting optical fiber of the B-end equipment port and the input port of the optical splitter, between the light-receiving optical fiber of the A-end equipment port and the output port of the optical splitter, and between the light-receiving port of the optical splitting system and the output port of the optical splitter, and recording the corresponding optical splitter and port numbers.
After the monitoring device determines the difference between the acquired first optical power and the transmission loss power as the third optical power output by the optical splitter, the method further includes: the monitoring equipment acquires a preset distribution proportion of the first optical power; the monitoring equipment determines the target receiving optical power of network elements on two sides of the optical splitter and the target receiving optical power of the optical splitting system according to the preset distribution proportion of the first optical power and the third optical power; and under the condition that the target receiving optical power of the network element ports on the two sides of the optical splitter is different from the actual receiving optical power of the network element ports on the two sides of the optical splitter, the monitoring equipment sends out information that the network element ports on the two sides of the optical splitter receive abnormity.
In some optional embodiments, in a case that optical power received by network element ports on both sides of the optical splitter is substantially smaller than target received optical power, it may be determined whether there is a case of adding an optical splitting link privately by checking a link.
After the monitoring device sends out the information received by the network element ports on both sides of the optical splitter, the method further comprises the following steps: and the monitoring equipment sends the abnormal information received by the network element ports on the two sides of the optical splitter to a remote monitoring system interface for displaying.
For example: and displaying that the A equipment port receives an abnormal alarm on the system interface.
Under the condition that the difference value between the second optical power and the third optical power is smaller than the preset threshold, before the monitoring device sends the information that the light splitting of the light splitter is normal, the method further comprises: the monitoring equipment acquires input flow of an input port of the optical splitter and output flow of an output port of the optical splitter; and under the condition that the input flow is equal to the output flow, the monitoring equipment sends out the information that the light splitting of the light splitter is normal.
It should be noted that, because the current egress devices are routers, there are many limitations on port mirroring, and 1: 1, the mirror image brings great pressure to the port number and the equipment cost, and the configuration of the egress router is needed in the later adjustment, which is extremely high risk. The mode of collecting flow through the optical splitter has the advantages of lowest cost, no need of configuring the outlet router in the later period and no risk.
In some optional embodiments, the acquiring, by the monitoring device, the first optical power input by the input port of the optical splitter and the second optical power output by the output port of the optical splitter includes: the monitoring equipment determines an equipment port connected with an input port of the optical splitter and an output port of the optical splitter; the monitoring device marks the device ports connected to the input port and the output port of the optical splitter, and displays the device ports on the interface of the remote monitoring system, specifically, taking the optical splitting monitoring apparatus in fig. 3 as an example, the monitoring system monitors the devices on both sides of the optical splitter, including the a-side device, the B-side device, and the optical power of each port of the optical splitting system. Performing a splitting operation in the field would break A, B the fiber between the devices and connect the splitter in series into A, B the device fiber link, with the fiber connection from the splitter to the splitting system. The monitoring system identifies the corresponding relation between the light-emitting optical fiber of the A-end equipment port and the input port of the optical splitter, the light-receiving optical fiber of the B-end equipment port and the output port of the optical splitter, and the corresponding relation between the light-receiving optical fiber of the optical splitting system and the output port of the optical splitter through the change conditions of the optical power of each equipment port before and after the optical splitting operation. And synchronously identifying the corresponding relation between the light-emitting optical fiber of the B-end equipment port and the input port of the optical splitter, the light-receiving optical fiber of the A-end equipment port and the output port of the optical splitter, and the light-receiving optical port of the optical splitting system and the output port of the optical splitter. The monitoring system synchronizes the corresponding relation to the resource system, the resource system adds a device port light splitting identifier, records the corresponding optical splitter and port number, and realizes the binding of the device port of the resource system and the port of the on-site passive optical splitter. For example: the split optical identifier may be a character string used to indicate a link connection order, for example: the optical signal is output from the output port of the optical splitter and correspondingly input to the receiving port of the B equipment and the receiving port of the B-end optical splitting system;
the first input port of the optical splitter corresponds to the optical fiber emitting port of the device a and the like.
