Description

Technical Field

[0001] The present invention relates to the technical field of optical communication devices, and in particular to a dense wave multiplexing method for optical module communication and an optical module. Background Art

[0002] As an important module supporting data transmission in the Internet and data centers, the transmission rate and transmission distance of optical modules have a great impact on the transmission bandwidth of the Internet and data centers. In order to improve the transmission bandwidth of the Internet and data centers, optical modules are required to have a certain transmission rate and transmission distance. There are two common 8-channel optical module technical solutions: the first is an optical module made by cascading conventional DWDM devices. The conventional DWDM devices of the optical modules of this solution are large in size and the materials are numerous and complex. This means that the loss of the last channel of the cascaded modules will inevitably be greater than the previous channel, and the overall loss of the product will be large. Large loss means more energy loss, which is not conducive to reducing energy consumption.

[0003] The second is an optical module made of free-space DWDM. The DWDM diaphragm of the optical module of this solution causes a large collimator optical path. The optical path transmitted to the last channel is no less than 216mm. The current common collimator effective optical path is about 100mm, which will lead to losses caused by drastic changes in the light spot due to the large optical path. At the same time, due to the need to transmit a long distance in the lateral direction, the size of the product is relatively long, which cannot meet the market's popularization needs.

[0004] Based on the above, it is urgent to design a dense wave multiplexing method for optical module communication, which can eliminate the loss caused by the drastic change of the light spot due to the long optical path while ensuring the size of the 8-channel optical module, and alleviate the problem of large product loss due to the large optical path. Summary of the invention

[0005] The purpose of the present invention is to provide a dense wave multiplexing method and an optical module for optical module communication, by judging whether the current optical fiber transmission quantity of the laser receiving end is within the preset optical fiber transmission threshold, so as to eliminate the loss caused by the drastic change of the light spot due to the large optical path when the data is merged, aiming to solve the problems in the prior art.

[0006] The present invention is implemented in this way: a dense wave multiplexing method for optical module communication is applied to optical communication equipment, specifically comprising the following steps:

[0007] S101: Acquire the optical fiber transmission quantity of the current laser receiving end of the wavelength division multiplexer, and determine the internal channel usage status of the current laser receiving end;

[0008] S102: Determine whether the current optical fiber transmission number of the laser receiving end is within a preset optical fiber transmission number threshold. If the current optical fiber transmission number of the laser receiving end is within the preset optical fiber transmission number threshold, perform data convergence according to the acquired current optical fiber transmission number of the laser receiving end, and couple the optical lines for transmission in the same optical fiber.

[0009] S103: If the optical fiber transmission quantity of the current laser receiving end is not within the preset optical fiber transmission threshold, according to the obtained optical fiber transmission quantity of the current laser receiving end and the current optical power of the combined current laser receiving end, the current optical power is adjusted to obtain a compensation optical power signal, and the compensation optical power signal is fed back;

[0010] S104: Acquire a compensation optical power signal, and adjust the current optical power signal according to the compensation optical power signal to generate a target compensation optical power signal for signal transmission;

[0011] S105: Acquire a coupled optical line at the current laser transmitting end of the wavelength division multiplexer, separate optical signals of various wavelengths, and further process them by an optical receiver to restore the original signal power for transmission.

[0012] Furthermore, in S101, the number of optical fiber transmissions at the current laser receiving end of the wavelength division multiplexer is obtained, including:

[0013] An optical signal meter is provided at the input end of the current laser receiving end of the wavelength division multiplexer, and the optical signal meter receives the optical signal sent by the laser;

[0014] After receiving the optical signal, signal recognition is performed to obtain the number of optical signals currently input into the optical signal meter;

[0015] The acquired optical signals are marked respectively, and the optical signals are sorted according to the marks. After the sorting is completed, the output angle of the optical signal is adjusted, so that the adjusted optical signals are output to the current laser receiving end of the wavelength division multiplexer in sequence according to the sorting.

[0016] Further, after receiving the optical signal, signal recognition is performed to obtain the number of optical signals currently input into the optical signal meter, including:

[0017] Acquire multiple optical signal recognition models, and sort the characteristic values ​​of the optical signal recognition models in descending order;

[0018] The received optical signal is acquired, and the received optical signal is input into the optical signal recognition model ranked first.

[0019] Further, after the sorting is completed, the output angle of the optical signal is adjusted so that the adjusted optical signal is sequentially output to the current laser receiving end of the wavelength division multiplexer according to the sorting, including:

[0020] A plurality of lens modules are arranged in the optical signal meter, the lens modules are placed in the optical signal channel, and the optical signal is directly projected into the lens module for azimuth adjustment;

[0021] The lens module adjusts the output direction according to the identification of the optical signal, and after the adjustment is completed, the output light is output to the current laser receiving end of the wavelength division multiplexer in sequence.

[0022] Further, in S103, according to the obtained optical fiber transmission quantity of the current laser receiving end and the current optical power of the combined current laser receiving end, the current optical power is adjusted to obtain the compensation optical power signal, and the compensation optical power signal is fed back, including:

[0023] Obtain the specific number of optical fiber transmissions at the current laser receiving end, merge the optical fiber transmissions, and complete the coupling processing of optical fiber signals;

[0024] Acquire the optical fiber signal after coupling processing, identify the current optical power of the optical fiber signal, compare the identified optical power value with the preset optical power value, and obtain a compensation optical power signal;

[0025] The compensation optical power signal is obtained and sent to the compensator, and the compensator compensates the optical power of the optical fiber signal to compensate the current optical power of the optical fiber signal to a preset optical power value for transmission.

[0026] Furthermore, in S105, a coupled optical line is obtained at the current laser emission end of the wavelength division multiplexer, and optical signals of various wavelengths are separated, including:

[0027] The current laser transmitting end of the wavelength division multiplexer identifies the coupled optical line and restores the power of the compensated optical fiber signal to ensure that it is the same as the current optical power at the receiving end of the wavelength division multiplexer;

[0028] By using the characteristic values ​​of multiple optical fiber transmission values ​​obtained in the optical signal meter, optical signals of various wavelengths are separated in turn. After the separation is completed, power detection is performed to ensure that the original signal power is restored for transmission.

[0029] Compared with the prior art, the dense wave multiplexing method for optical module communication and the optical module provided by the present invention have the following beneficial effects:

[0030] 1. Through the optical signal meter, the optical fiber transmission quantity of the current laser receiving end of the acquired wavelength division multiplexer is realized, and the optical fiber signal is marked and sorted for output. When the optical signal data is merged, by judging whether the optical fiber transmission quantity of the current laser receiving end is within the preset optical fiber transmission threshold, it is judged that when the data is merged, the loss caused by the drastic change of the light spot due to the long optical path can be eliminated, thereby reducing the problem of large product loss caused by the large optical path;

[0031] 2. If the current number of optical fiber transmissions at the laser receiving end is not within the preset optical fiber transmission threshold, the current optical power will be adjusted to obtain the compensation optical power signal, and the compensation optical power signal will be fed back to obtain the compensation optical power signal, and the target compensation optical power signal will be generated for signal transmission. This can effectively reduce the optical system spot. When the wavelength division multiplexer is working, it generates a periodic optical signal that is still lower than twice its optical power after compensation. Due to the periodicity of the convergence of optical signal data, the optical signal is limited by the set number of optical fiber transmissions and the optical power transmission, thereby achieving the effect of reducing the spot and reducing the loss.
