Abstract: An optoelectronic assembly having a heat sink, and in particular to an optical receiver or transmitter unit for use in an optical fibre communication system in which a heat sink is provided to carry away heat generated by electrical components within the unit. The optoelectronic assembly comprises an optical transceiver unit, a heat sink and a housing. The optical transceiver unit has an interior containing at least one optoelectronic device with at least one electrical connection to said device for providing electrical power to the device, the electrical connection being made through an electrical contact on an external surface of the optical transceiver unit. The heat sink is mounted to the optical transceiver unit and is in thermal contact with both the optical transceiver unit and the housing to convey waste heat from within the optical transceiver unit to the housing.

Abstract: An optical module and chassis incorporating “keying” features that ensure the correct insertion of the module into a given chassis, thereby preventing damage to the module and/or the system to which the chassis is connected.

Abstract: An optical networking system has connector blocks, each having a series of sockets. Each socket receives an optical transceiver and provides a full EMI shield. An active cooling system has heat pipes for drawing heat from the devices, through the sockets and to a heat exchanger.

Abstract: A module houses an optical transceiver device and provides a dedicated heat-transfer environment for the device. A fan draws in ambient air and blows it through a heat exchanger and out an exhaust. Heat transfer is by conduction from the device into the heat exchanger through an opening in an EMI shield of the device. In some embodiments the fan is a pluggable unit, allowing quick replacement if status LEDs indicate a fault.

Abstract: A pluggable optical module for use with optical communication systems, wherein the pluggable optical module comprises a housing having an opening arranged to receive a subassembly, wherein the subassembly is capable of being removably inserted into the housing.

Abstract: An optical package that includes a component for supporting a printed circuit board. The optical package comprises a housing containing a printed circuit board having a connecting edge for connecting to external components; an optical component supported by the printed circuit board; an optical connector for coupling the optical component to an optical fibre; and a support supporting the connecting edge.
