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.
