Optical transceiver assembly, an optical transceiver and an adaptor for an optical transceiver

Abstract

An optical transceiver assembly is provided. The optical transceiver assembly comprises: an optical transceiver, wherein the optical transceiver comprises: an optical transmitter comprising an active region of a cavity laser for transmitting optical signals over a first channel of the optical transceiver; an optical receiver for receiving optical signals over a second channel of the optical transceiver; and an adaptor. The adaptor comprises: a first terminal, the first terminal for coupling to one of the first channel and the second channel of the optical transceiver; a second terminal, the second terminal for coupling to the other of the first channel and the second channel of the optical transceiver; a third terminal defining a bidirectional optical channel of the adaptor; and one or more optical components configured to optically couple the first and second terminals to the third terminal, such that optical signals at a first wavelength pass between the first terminal and the third terminal, and optical signals at a second wavelength, different from the first wavelength, pass between the second terminal and the third terminal. The active region and one or more of the optical components of the adaptor are together configured to form the cavity laser for transmitting optical signals over the first channel. Optical signals may be received by the optical transceiver over the second channel. The adaptor may be couplable to the optical transceiver in a first configuration, in which the first terminal of the adaptor is coupled to the first channel and the second terminal of the adaptor is coupled to the second channel, and a second configuration, in which the second terminal of the adaptor is optically coupled to the first channel and the first terminal of the adaptor is optically coupled to the second channel. An optical transceiver and an adaptor for an optical transceiver are also provided.
