TRANSCEIVER HYBRID MODULE FOR THE BIDIRECTIONAL TRANSMISSION ON A MONOMODAL FIBRE OPTIC OF TWO OPTICAL SIGNALS

摘要

It is described an hybrid optical device including, within the same container, a receiver for optical signals, a generator of optical signals (laser or LED), as well as an optical system abutting to which are the laser, the receiver (through a cut-down size of fibre optic) and a monomodal fibre optic in which the optical signal to be transmitted, generated by the laser, and the one to be received, destined to the receiver, may propagate: the optical system allows the superimposition of the two optical signals (transmitted and received) in the monomodal fibre optic and insulates the receiver and the laser between them.
