Receptacle assembly for receiving a pluggable module

A receptacle assembly for mating with first and second pluggable modules, the receptacle assembly comprising:

• a cage comprising an interior cavity and a divider that divides the interior cavity into first and second ports, the cage having a front end that is open to the first and second ports, the first and second ports configured to receive the first and second pluggable modules, respectively, therein through the front end, the divider comprising an internal compartment that extends between the first and second ports;
• first and second receptacle connectors held within the first and second ports, respectively, for mating with the first and second pluggable modules, respectively;
• and
• a thermal transfer assembly comprising a base, a spring, and a heat pipe, the base being received within the internal compartment of the divider and comprising a module side that faces the first port, the spring being operatively connected between the divider and the base such that the spring is configured to bias the base toward the first port and thereby press the module side of the base into thermal communication with the first pluggable module when the first pluggable module is received within the first port, the heat pipe comprising a base segment that is connected in thermal communication with the base, the heat pipe comprising a transfer segment that extends away from the base segment for carrying heat away from the base.
