Optical transmission receiver module and producing method, electronic device using with the same module

Abstract

In an optical transmitter-receiver module for performing optical transmission and reception by using a single-core optical fiber, a light-tight partition plate unit 506 for separation between an optical path of a transmission signal light and an optical path of a reception signal light is held between a jack section 508 for detachably holding an optical plug 240 and a light emitting / receiving unit 505 having an LED 514 and a PD 515 positioned and fixed in place and molded in one piece.

Description

technical field [0001] The present invention relates to an optical transceiver module and electronics for a single-core bidirectional optical transceiver system capable of transmitting and receiving with a single-core optical fiber. In particular, the present invention relates to a digital communication system capable of high-speed transmission such as IEEE1394 (Institute of Electrical and Electronics Engineers 1394) and USB (Universal Serial Bus) 2.0. The invention also relates to a method of manufacturing an optical transceiver module. Background technique [0002] Conventionally, as the first optical transceiver module, one is described in Japanese Patent Laid-Open No. 2001-116961. In this optical transceiver module, full-duplex communication is achieved by using shielding plates to reduce electrical crosstalk and simultaneously using opaque partitions to reduce optical crosstalk. The plate abuts against the end face of the optical fiber to separate the light emitting d...

AI Technical Summary

Problems solved by technology

Therefore, similar to the first conventional optical transceiver module, there is a problem that the end face 1102 of the optical fiber and / or the partition plate 1111 are damaged.

Furthermore, in this second optical transceiver module, the light-emitting element 1103 and the light-receiving element 1105 are mounted on the same substrate 1109, but the optical positions of the light-emitting element 1103 and the light-receiving element 1105 are not relative to those having the partition plate 1111. The optical system is optimized
