OPTICAL TRANSMISSION/RECEPTION MODULE

摘要

A small optical transmission/reception module which is free from a stress caused by differences in thermal expansion coefficient among a transmission unit optical system, a reception optical system and members that integrates and fixes them together, and is not affected by a stress when an optical connector is attached or detached. The optical transmission/reception module comprises, all optically coupled together and mechanically integrated and fixed, a transmission unit optical system (1) including a light emitting element and an optical fiber or an optical waveguide optically coupled with a light emitting element, the electrical input terminal of a light emitting element being a flexible cable, a reception unit optical system (2) including a light receiving element and an optical fiber or an optical waveguide optically coupled with a light receiving element, the electrical output terminal of a light receiving element being a flexible cable, and a light outputting/receiving optical receptacle (3), wherein two flexible cables are spatially disposed away from each other.
