Technical Field

The invention relates to a dynamic power optical communication transceiving component based on an FPGA (field programmable gate array).

Background

One problem with optical communications is that the amount of optical power of the optical transmitting unit is related to the condition of the optical transmission path. If the optical power is too high, the output of the photosensitive device at the receiving party is saturated, and the receiving error rate is increased; if the optical power is too small, the reception sensitivity is also lowered, and the reception error rate is also increased. Therefore, it is an ideal method to adjust the optical power in time according to the bit error rate distribution of both the transmitter and the receiver.

Disclosure of Invention

In order to solve the problem that the optical power of the light emitting unit is adjustable, the invention provides a dynamic power optical communication transceiving component based on an FPGA.

The technical scheme adopted by the invention for solving the technical problems is as follows: a dynamic power optical communication transceiving component based on an FPGA comprises a data sending unit, an FPGA optical power adjusting unit and an optical transmitting unit. The electric signal of the data sending unit is connected to the input end of the FPGA optical power adjusting unit, and the output end of the FPGA optical power adjusting unit is connected with the light emitting unit. And the FPGA optical power adjusting unit adjusts the optical transmission power by analyzing the data frame short code instruction.

The invention has the following beneficial effects: compared with fixed power, the dynamic power optical communication transceiving component based on the FPGA can dynamically adjust the light emission power according to the data frame short code instruction, and is beneficial to reducing the receiving error rate.
