Enhanced optical module cooling with angled fins

Abstract

An optical module, such as a Quad Small Form Factor (QSFP) or variant thereof, or another type of module, includes a housing; an optical subassembly positioned within the housing at an angle relative to the housing; circuitry connected to the optical subassembly; and heat fins located on and in contact with the housing, wherein the heat fibers are positioned near the optical subassembly. The angling of the optical subassembly supports improved thermal performance, i.e., larger heat fin area at locations due to the angle, and eliminates any bend radius issues on fibers exiting the optical subassembly.
