OPTICAL TRANSMITTER/RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide an optical transmitter/receiver capable of single-fiber two-way transmission which can reduce crosstalks between optical transmitting/receiving circuits.

SOLUTION: In the optical transmitter/receiver for performing single-fiber two-way transmission by using an optical fiber, an optical separating coupling part is inserted between a light-emitting part and a light-receiving part; thereby the optical transmitting/receiving circuits are electrically separated, an optical signal from the light-emitting part is absorbed by an optical absorbing part which is disposed on the optically separating coupling part, therethrough; and the influence on the light-receiving part is suppressed and the electrical and optical crosstalks between the optical transmitting/receiving circuits can be reduced.
