Abstract: 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.

Abstract: A modular jack for housing magnetic components includes a housing which has a plurality of ports each of which can receive an electrical connector. Extending into each of the ports are a plurality of contacts for connecting to contacts of an electrical connector. The ports may be arranged in a stacked configuration in which case the modular jack is a double deck jack. Attached to the housing may be one or more magnetic housing. Each magnetic housing can house at least one magnetic component, which can be a transformer. Preferably, there is a magnetic housing for every two ports, and the magnetic housing houses a magnetic component for each port. Shields an be installed into the housing between the magnetic components in order to provide isolation of the components. A printed wire board can be attached to the magnetic housing, and a contact carrier having a plurality of contacts can be attached to the printed wire board.
