Bi-directional Optical Transceiver Module

Abstract

Disclosed is a bi-directional optical transceiver module, which is capable of effectively separating optical signals even when wavelength bands of a first optical signal output from an optical fiber and a second optical signal output from an optical transmitter are narrow.

Description

technical field [0001] The invention relates to a bidirectional optical transceiver module used in optical communication. Background technique [0002] Generally, an optical module refers to a module in which various optical communication functions are concentrated in one package to connect with an optical fiber. Recently, a bidirectional optical module is mainly used, in which an optical transmitter and an optical receiver are adjusted to one module, the optical transmitter uses a laser diode which has low power consumption and can satisfy a long distance as a light source, and the optical The receiver uses photodiodes for optical communication. [0003] The bidirectional optical module includes an optical transmitter, an optical receiver, an optical filter, an optical fiber, a support for accommodating the optical fiber, and the like. A first optical signal (incident light) output from the optical fiber is reflected by the optical fiber to enter the optical receiver, and...

Problems solved by technology

[0004] Usually, the optical filter is set at an inclination of 45° to separate the first optical signal and the second optical signal, but when the wavelength interval of the first optical signal and the second optical signal is 60nm or less, especially, at -40°C to In an environment of 85°C, it is impossible to separate the optical signal according to the performance of the filter
