1. A module for use in a network element, the module comprising:
a Printed Circuit Board (PCB);
a faceplate connected to the PCB;
a plurality of cage assemblies connected to the PCB, each cage assembly is configured to receive a pluggable optical module via a corresponding opening in the faceplate; and
a shared heat exchanger that is integrally formed and substantially covers the plurality of cage assemblies, wherein the shared heat exchanger is configured to cool multiple pluggable optics in the plurality of cage assemblies;
wherein the shared heat exchanger is a cold plate including a single cooling line that provides liquid cooling to the multiple pluggable optics.
