Description
The present application is a divisional application, the original application having application number 201910513579.4, the original application date being 2019, 6 and 14, the entire content of the original application being incorporated by reference in the present application.
Technical Field
The application relates to the technical field of optical fiber communication, in particular to an optical module information interaction method and an optical module.
Background
With the increasing demand of users for network bandwidth, Wavelength Division Multiplexing (WDM) technology has been gradually applied to the access layer of the metro network from the backbone network and the metro network, and the metro access type optical network based on the WDM technology is widely applied.
Fig. 1 is a schematic structural diagram of a typical wdm-ac optical network system. As shown in fig. 1, the system mainly includes an optical network Near End 100(NE, Near End), an optical network Far End 200(FE, Far End, or RE, Remote End), and a transmission link 300. In transmission link 300, an optical add/drop multiplexer (OADM) may be included. In order to improve the flexibility of the dynamic configuration of the network wavelength, wavelength-Tunable optical modules, for example, single-fiber bidirectional Tunable-BIDI optical modules, are configured at the optical network near end 100 and the optical network far end 200. Further, in order to facilitate the application of the wavelength tunable optical module, an optical wavelength division multiplexer/demultiplexer is generally respectively configured at the optical network near end 100 and the optical network far end 300, the two optical wavelength division multiplexers/demultiplexers have the same wavelength characteristics, N channels, and channel periodicity, and each channel allows light of two wavelengths to pass through, for example, channel 1 can only pass light of wavelengths λ 1-1 and λ 1-2, and channel N can only pass light of wavelengths λ N-1 and λ N-2. In the above system, taking the optical module 101 of the optical network near end 100 and the optical module 201 of the optical network far end 200 in fig. 1 as an example, if the optical module 101 is connected to the channel 1-1 of the optical wavelength division multiplexer/demultiplexer of the optical network near end 100, the corresponding transmission optical wavelength is λ 1-1, and the corresponding reception optical wavelength is λ 1-2; the optical module 201 is connected to a channel 2-1 of the optical wavelength division multiplexer/demultiplexer at the far end 200 of the optical network, and correspondingly, the transmitting optical wavelength is λ 1-2 and the receiving optical wavelength is λ 1-1. At this time, the communication between the optical module 101 and the optical module 201 can be realized, and the optical module operating at other wavelengths and the two optical modules have no signal transmission and no mutual influence.
Based on the above system, the optical transceivers at the optical network near end 100 and the optical network far end 200 are all one-to-one wavelength, so in the installation and maintenance process of the existing wavelength division multiplexing-based access type optical network system, an operator needs to manually configure the wavelength of the optical module according to the number of channels of the optical wavelength division multiplexer/demultiplexer, which is not only easy to make an error, but also needs to carry a computer and other equipment to configure, resulting in waste of manpower and financial resources. In order to reduce the workload of the staff and facilitate the control of the optical module of the optical network far end 200 by the optical network near end 100 in the using process, some optical modules may modulate a control signal in the normal service signals of the two optical modules. By using the control signal, the management and maintenance work such as optical module wavelength configuration, system upgrade, etc. of the optical network near end 100 to the optical network far end 200 is realized. However, since the control signal is modulated in the normal traffic signal, normal traffic communication is affected.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In order to facilitate automatic adjustment of the emission wavelength of the optical module and management of the optical module at the far end of the optical network at the near end of the optical network in an access type optical network system based on wavelength division multiplexing, the embodiment loads a low-frequency signal on the basis of a normal service signal, increases the function of a message channel, and realizes automatic management and maintenance of the optical module between the near end of the optical network and the far end of the optical network.
Fig. 2 is a schematic basic flow chart of an optical module information interaction method according to an embodiment of the present application. As shown in fig. 2, the method specifically includes the following steps:
s110: the method comprises the steps that a first optical module transmits an optical signal loaded with a low-frequency message channel signal to a second optical module, wherein the optical signal is a normal service signal; and the low-frequency message channel signal is used for indicating that the second optical module is to transmit a second wavelength corresponding to the optical wavelength division multiplexing/demultiplexing device channel where the first optical module is located.
In this embodiment, the first optical module may be an optical module at a near end of an optical network, and the second optical module may be an optical module at a far end of the optical network; the two optical modules are wavelength-adjustable optical modules, and can be controlled by software to switch channels of the optical modules to different working wave bands.
After the first optical module is connected to the optical wavelength division multiplexer/demultiplexer at the near end of the optical network, for example, connected to the first channel of the optical wavelength division multiplexer/demultiplexer, the transmission wavelength of the first optical module is configured to be λ 1-1, which is the wavelength that the optical wavelength division multiplexer/demultiplexer can pass through. In order to facilitate switching of the light emitting wavelength of the first optical module, a system automatic configuration mode may be adopted, and specifically, a system, such as an upper computer, where the first optical module is located configures the optical signal, of which the emitting wavelength is matched with the channel number, according to the channel number of the optical wavelength division multiplexer/demultiplexer connected to the first optical module.
After the configuration of the light emitting wavelength of the first optical module is completed, a low-frequency message channel signal matched with the channel number is loaded in the optical signal emitted by the first optical module, for example, a low-frequency 50Kbps signal is added on the basis of a 10Gbps or 25Gbps optical signal. When loading the low-frequency message channel signal, the laser in the first optical module may be configured as follows: adding a low-frequency signal to the bias direct current; and adding a low-frequency modulation signal to the direct current negative voltage bias. Of course, the modulation method is not limited to the above modulation method.
In order to enable a low-frequency message channel signal sent by a first optical module to be applicable to different types of optical modules and reduce content of signal transmission, the low-frequency message channel signal set in this embodiment may include a switch channel instruction and a target channel code, where the switch channel instruction is used to instruct a second optical module to perform transmission wavelength switching; the target channel code is used for enabling the second optical module to search for a debugging parameter corresponding to the target channel code from a preset channel code lookup table so as to switch the emission wavelength to the first wavelength, specifically, the second optical module may set different channel code lookup tables for different channels, the lookup tables include the debugging parameter with the content related to the wavelength, for example, the distributed bragg reflector laser may be a semiconductor cooler and a distributed bragg reflector parameter, and then the working parameter modulation is performed according to the searched modulation parameter, so as to realize the emission wavelength switching. It should be noted that the target channel coding may be replaced by a target wavelength, as long as the target channel information of the work can be indicated.
Further, the low frequency message channel signal may be implemented in a coding manner, for example, 1011 is used as a channel switching instruction, and then a target channel coding is added, for example, 01 represents channel 1, and 02 represents channel 2. The first optical module may be provided with a certain register for storing information of the low frequency message channel signal and written by means of I2C.
S120: and the first optical module judges whether an optical signal with a second wavelength sent by the second optical module is received.
The optical signal with the first wavelength sent by the first optical module can only pass through the first channel of the optical wavelength division multiplexer/demultiplexer, sequentially passes through the optical wavelength division multiplexer/demultiplexer at the near end of the optical network, and then is sent out from the first channel of the optical wavelength division multiplexer/demultiplexer at the far end of the optical network. At this time, after the second optical module is inserted into the first channel of the optical wavelength division multiplexer/demultiplexer at the far end of the optical network, the second optical module can receive the optical signal with the first wavelength and simultaneously receive the loaded low-frequency message channel signal. After the second optical module analyzes the low-frequency message channel signal, the transmitting wavelength can be switched to a second wavelength corresponding to the first channel according to the content of the low-frequency message channel signal.
In order to implement the second optical module to receive the low-frequency signal, a conventional high-frequency signal receiving circuit, such as a photoelectric converter, a transimpedance amplifier and a 10G limiting amplifier, which are connected in sequence, may be configured inside the second optical module, and meanwhile, a low-frequency receiving circuit is configured to receive the low-frequency message channel signal.
Further, the low frequency receiving circuit may be implemented by configuring an isolation circuit on the high frequency signal receiving circuit, for example, in an optical module compatible with 1G and 10G services, an input end of the isolation circuit is connected to an output end of a 1G limiting amplifier thereof, and is configured to isolate the 1G signal amplified by the 1G limiting amplifier and select a low frequency message channel signal amplified by the 1G limiting amplifier.
Based on the above configuration, if the first optical module receives the optical signal of the second wavelength emitted by the second optical module, step S130 is executed; otherwise, the process may return to continue to execute step S130.
S130: the first optical module dismisses the LOSs indication LOS alarm for the second optical module.
After the first optical module receives the optical signal with the second wavelength sent by the second optical module, the LOS alarm of the LOSs indication of the second optical module can be released, the transmission of the low-frequency message channel signal is closed, and then the communication function of the first optical module and the second optical module is completed.
With the method provided in this embodiment, after the first optical module is inserted into a certain channel in the optical wavelength division multiplexer/demultiplexer at the near end of the optical network, the wavelength light corresponding to the channel is modulated and transmitted, and the low-frequency message channel signal is loaded in the signal of the wavelength. Meanwhile, a second optical module is inserted into a corresponding channel in an optical wavelength division multiplexer/demultiplexer of the optical network terminal, and after receiving an optical signal loaded with a low-frequency message channel signal sent by the first optical module, the transmitting wavelength of the optical signal is automatically switched to the wavelength corresponding to the channel. Because the low-frequency message channel signal is utilized, the second optical module can automatically configure the emission wavelength of the second optical module, compared with a manual configuration mode, the method is more accurate and can greatly reduce the manual workload; in addition, the method and the device load the low-frequency signal on the basis of the normal service signal, increase the function of the message channel, and further can not influence the normal service communication function.
After the first optical module and the second optical module are communicated, in the running process of the system, by using the message channel function of the optical modules, the first optical module can also acquire DDM (Digital Diagnostics Monitoring) information at the far end of the optical network so as to help the near end of the optical network to find out information such as the position of a fault in an optical fiber link and improve the reliability of the system. Fig. 3 is a basic flowchart illustrating another optical module information interaction method according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of:
s210: the first optical module transmits a first optical signal loaded with a low frequency command signal to the second optical module.
Wherein the first optical signal is a normal service signal. The low-frequency command signal is used for indicating the second optical module to report digital diagnosis monitoring information of the module, namely conventional monitoring information of the optical module, such as information of emitted light power, received light power, working voltage and the like; or, the second module may also be configured to instruct the second optical module to report digital diagnostic monitoring information of the system in which the second optical module is located, for example, the second module may set a certain register area, and the area may have state information such as a version number and a working state, which is written in by the system in which the second optical module is located through I2C; or, the second optical module can be instructed to report the digital diagnosis monitoring information of the module and the system where the module is located at the same time.
In this embodiment, the first optical module may be an optical module at a near end of an optical network, and the second optical module may be an optical module at a far end of the optical network; the two optical modules are wavelength-adjustable optical modules, and can be controlled by software to switch channels thereof, so that the optical modules are switched to different working wave bands.
Further, the mode in which the first optical module sends the low-frequency command signal to the second optical module may be an active sending mode or may also be sent under the control of the system in which the first optical module is located, specifically:

The command for acquiring the DDM information of the second optical module may be a specific value written in a register of the first optical module, for example, 101010 indicates that the first optical module is commanded to send a command to the second optical module, and the second optical module is requested to report the DDM information.
S220: and the first optical module receives a second optical signal which is sent by the second optical module and is loaded with the digital diagnosis monitoring information.
After receiving the first optical signal loaded with the low-frequency command signal, the second optical module loads the DDM information of the module and/or the stored system DDM information to the second optical signal through a message channel according to the low-frequency command signal, and then sends the DDM information and/or the stored system DDM information to the first optical module.
S230: the first optical module demodulates the digital diagnostic monitoring information from the second optical signal.
After the first optical module demodulates the digital diagnosis monitoring information sent by the second optical module from the second optical signal, the digital diagnosis monitoring information can be directly stored in the module and can be reported to a system where the module is located. The method comprises the following specific steps:
the first method is as follows: the first optical module stores the digital diagnosis monitoring information to a preset storage area for a system where the first optical module is located to read.
For example, a mapping region of module DDM information is set in the first optical module to store DDM information of the second optical module; in addition, a mapping area of the system DDM information is also set for the DDM information of the system where the second optical module is located.

In the two processing manners of the DDM information received by the first optical module in this embodiment, the first manner corresponds to the first implementation manner in step S210, and the second manner corresponds to the second implementation manner in step S210, but of course, the first manner may correspond to the second manner in step S210, and the second manner may correspond to the first manner in step S210.
In the method provided by this embodiment, a low-frequency signal for instructing an optical module to report digital diagnostic monitoring information is loaded on a normal service signal between an optical module at a near end of an optical network and an optical module at a far end of the optical network. Therefore, in the working process of the system, the remote optical module can automatically report the DDM information, and the system maintenance is facilitated. Meanwhile, the low-frequency signal is loaded on the basis of the normal service signal, the function of a message channel is added, and further the normal service communication function can not be influenced.
After the first optical module and the second optical module are communicated, in the running process of the system, the first optical module can also send a message to the second optical module by using the message channel function of the optical modules, and the remote equipment is controlled to carry out system upgrading. Fig. 4 is a basic flowchart illustrating another optical module information interaction method according to an embodiment of the present application.
