Step S201 in fig. 5 is the same as step S101 in fig. 1, and is not described herein again.
Step S202: and adjusting the amplification gain of the carrier signal according to the first pilot tone signal so as to enable the signal amplitude of the carrier signal to accord with a preset standard.
Step S202 in fig. 5 is the same as step S102 in fig. 1, and is not described herein again.
Step S203: and demodulating the first set top signal to acquire corresponding first device information of the first communication device, wherein the first device information is used for evaluating signal transmission stability between the first communication device and the second communication device.

In some embodiments, the communication method further includes:
and receiving second parameter adjustment feedback of the second optical interface by the second communication equipment, so that the first communication equipment adjusts the relevant parameters of the first optical interface according to the second parameter adjustment feedback.
Illustratively, after the second communication device 201 finishes adjusting the parameters of the second optical interface 2019, the optical communication information is sent to the first communication device 101 through the transmitting end of the second optical interface 2019 again, and if the first communication device 101 determines that the transmitting end of the second optical interface 2019 still needs to be adjusted according to the received signal, corresponding feedback information is generated again, so as to circulate.
When the adjustment of the parameter of the second optical interface 2019 cannot improve the signal transmission stability between the first communication device 101 and the second communication device 102, the second communication device 201 generates a corresponding second parameter adjustment feedback to send to the first communication device 101. The first communication device 101 adjusts the receiving end equalization parameter of the first optical interface 2019 of the first communication device 101 according to the second parameter adjustment feedback.
