Opto-electrical transceiver module and active optical cable

摘要

An opto-electrical transceiver module and an active optical cable comprising such a module are disclosed. The module includes a first printed circuit board and a second printed circuit board. The first printed circuit board carries 1) a light sources with driver circuitry that converts incoming electrical signals to optical signals, 2) optical receiver components with amplifier circuitry that converts optical signals to electrical signals, 3) a single optical coupling unit configured to optically coupling waveguides of an optical cable to the light sources as well as to the optical receiver components, and (4) one or more electrical contacts configured to connect to a host device. The second printed circuit board includes electrical contacts connected to the driver circuitry or to the amplifier circuitry on the first printed circuit board.
