Document Type and Number:
Japanese Patent JP2020181784
Kind Code:
A
Abstract:
To provide an optical communication module and an optical communication system that can prevent deterioration in the reception state of an optical signal and reduction in communication speed.SOLUTION: An optical communication module 10 includes: a light-receiving unit 20 that receives a first optical signal L1 and outputs a first analog electric signal corresponding to the first optical signal L1; a circuit unit 12 that converts the first analog electric signal into a first digital electric signal; and a terminal 13 that outputs the first digital electric signal to a communication apparatus 5. The light-receiving unit 20 includes: a housing 21 that air-tightly seals an internal space and has a light incident portion 22 for letting a first optical signal L1 enter; a photo cathode 25 that is provided in the internal space and receives the first optical signal L1; and an anode 26 that is provided in the internal space and outputs the first analog electric signal.SELECTED DRAWING: Figure 2
