Abstract

A receptacle assembly includes a receptacle housing having panels defining a housing cavity receiving a pluggable module. The panels are conductive to provide electromagnetic interference shielding. The receptacle housing has a bottom mounted to a circuit board. A communication module is received in the housing cavity and mounted to the circuit board. The communication module includes a communication connector interfacing with the pluggable module. The receptacle assembly includes a light pipe assembly coupled to the receptacle housing having has a plurality of flexible light pipes each extending between a light-receiving end and a light-emitting end. The light-receiving end is positioned proximate to the bottom to receive light from a light-emitting device mounted to the circuit board. The light-emitting end is provided proximate to the front end of the receptacle housing for displaying a status indicator for the communication connector.
