Bidirectional optical communication module

Abstract

In a bidirectional optical communications module capable of all-dual-mode communications using a single optical fiber, interference due to internally scattered light is reduced by forming a diverging area on a periphery of a transmission lens and providing a thin film reflection mirror which collects incoming light. A inexpensive, compact bidirectional optical communications module can be offered with reduced interference between outgoing and incoming light, especially, interference due to internally scattered light.

Description

technical field [0001] The present invention relates to a bidirectional optical communication module that utilizes an optical communication path element and an optical signal to perform bidirectional communication, and more specifically relates to a module that can be used in home communication, communication between electronic devices, and LAN (Local Area Network, local area network), etc. bidirectional optical communication module. Background technique [0002] With the development of an information society, attention is being paid to utilizing network technologies having optical communication path elements in optical communication paths through optical signals. An optical communication path element having an optical communication path through which an optical signal passes refers to an optical fiber or a plastic optical fiber. In particular, in recent years, POF has been applied to communication in the home and communication between electronic devices along with the redu...
