ELECTROMAGNETIC INTERFERENCE (EMI) WAVEGUIDE DEVICE FOR USE IN A PARALLEL OPTICAL COMMUNICATIONS MODULE, AND A METHOD

摘要

A parallel optical communications module is equipped with an EMI waveguide (WG) device having a tube-like structure that surrounds portions of one or more optical fiber ribbon cables that pass through the tube-like structure and connect to the module. The EMI WG device attenuates EMI to acceptable levels to provide the module with effective EMI shielding capability.
