As shown in fig. 6 and fig. 7, the signal analysis chipset 21 is configured to perform serial or deserialization on the electrical signals, because the signal extraction unit 12 is connected to the signal analysis chipset 21 through the signal transmission line group 13, where the signal transmission line group 13 includes a plurality of signal transmission lines, and a part of the signal transmission lines are configured to transmit the electrical signals from the signal extraction unit 12, where the signal analysis chip needs to perform serial on the electrical signals, and multiple electrical signals are combined together and transmitted to the light emitting component; the other part of transmission lines are used for receiving the electric signals from the light receiving assembly, at the moment, the signal analysis chip needs to deserialize the electric signals from the light receiving assembly, divide and divide the single-channel electric signals into a plurality of transmission lines, and send the single-channel electric signals to the signal extraction unit 12; the serial or deserialized mode comprises one or more modes of signal serial processing, amplitude modulation, multi-order amplitude modulation, phase modulation, frequency modulation, time division multiplexing, code division multiplexing and space division multiplexing.

the power receiving chip set 26 is connected with the power transmission path 4 and is used for receiving the power in the power transmission path 4, and the power receiving chip supplies power to the circuit board assembly 2 through the received power.
The circuit board assembly 2 can be powered by a separate external power supply, but requires additional space for power supply deployment, resulting in an increase in complexity of the structure, so that the circuit board assembly 2 in this embodiment uses a part of the electrical energy from the front end and a part of the electrical energy received from the opposite end to power; as shown in fig. 8 and 9, the power receiving chipset 26 is separately routed and connected to the power transmission path 4, so that the optoelectric composite interface 3 is connected in parallel with the power receiving chipset, when power is sent from the front end, the power is sent from the signal extracting unit 12 and is sent through the power transmission path 4, when the power passes through the branch path of the power receiving chipset 26, a part of the power is sent to the optoelectric composite interface 3 and is sent to the opposite end, and another part of the power is sent to the power receiving chipset 26 for supplying power to the circuit board assembly 2, and for protecting the circuit board assembly 2, a voltage meeting the circuit board standard needs to be supplied to the circuit board assembly 2, so that the power receiving chipset 26 is set with a preset voltage threshold, and when the power reaches the preset voltage threshold, the power receiving chipset provides power to each component on the circuit board assembly 2 for supplying power for the operation of the circuit board assembly 2.
