Pluggable optical module thermal management and heat shield assemblies, devices, and methods
The present disclosure provides pluggable optical modules that are prevented from reaching potentially dangerous temperatures when a fiber optic connector is not present and engaged with the associated module housing. Further, the present disclosure provides fiber optic connectors and/or pluggable optical modules that incorporate a port heat shield external to the associated face plate when the pluggable optical modules and fiber optic connectors are engaged, thereby preventing a user from contacting potentially hot and dangerous metallic surfaces of the module housings, as well as providing access for cooling air flow. The solutions presented herein are equally applicable to fixed optical ports and connectors as well.
1. A heat shield device, comprising:
an isolating clip structure with a retention portion one of fixedly and removably coupled to an end portion of a fiber optic connector and a protection portion adapted to be one of fixedly and removably disposed about an exposed end portion of a housing of an optical module;
wherein the isolating clip structure defines a protective envelope about a port of the optical module adapted to receive the fiber optic connector, the fiber optic connector, and the exposed end portion of the housing such that a protruding portion of the housing that includes the port is substantially surrounded thereby.
2. The heat shield device of claim 1 , wherein the protection portion of the isolating clip structure is adapted to be one of fixedly and removably disposed about one or more of an exposed top surface, and exposed bottom surface, and an exposed side surface of the optical module.
