As a professional optical module thermal system B2B service provider, we collaborated with a communication equipment manufacturer to develop a QSFPDD optical module thermal solution for their OTN equipment. The client required not only that the heatsink design meet stringent thermal performance requirements but also that the heatsink be integrated and assembled with the optical module Cage for shipment. This project faced two major challenges: translating the conceptual thermal structure into a manufacturable solution, and the client's lack of optical module Cage supply chain resources. Read More

Executive Summary: A Common Engineering Challenge
As high-speed optical modules evolve towards higher density and miniaturization, the conflict between thermal performance and mechanical structure has become a widespread industry pain point. Mature form factors like CFP2 often face the fundamental contradiction between "enhanced cooling requiring space" and "fixed system layout space." This article systematically deconstructs, through a typical case study, how to achieve dual breakthroughs in performance and compatibility without altering the main system architecture, via innovative thermal conduction processes and co-design of structures.

A globally leading Tier-1 communications equipment client encountered critical thermal management challenges during the development of their next-generation coherent optical modules. The module contains two heat sources, each operating at 13W with a compact size of 27×13mm, while the system's permissible air cooling capacity is limited to only 10CFM. The client required the overall thermal resistance to be strictly maintained within 0.6°C/W and sought comprehensive thermal technology support spanning thermal design, prototype development, testing, and mass production.
