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.
Claims13
An optical transmitter-receiver module having a light-emitting element for emitting transmission signal light and a light-receiving element for receiving reception signal light, said module being able to perform both transmission of the transmission signal light and reception of the reception signal light by means of a single-core optical fiber, said module comprising:
- a jack section for detachably holding an optical plug provided at an end portion of the optical fiber;
- a light emitting/receiving unit having the light-emitting element and light-receiving element positioned and fixed in place and molded in one piece;
- and
- a light-tight partition plate unit for separating an optical path of the transmission signal light and an optical path of the reception signal light from each other, said light-tight partition plate being arranged so as to be held between the jack section and the light emitting/receiving unit.
