Teardown: Source Photonics 800G OSFP Optical Module SPQ2-8E2-8FO-COA-FB1
2026-08-23 · Compiled by Best IT Parts from public industry reporting
In AI compute clusters and hyperscale cloud data centers, massive data exchange between servers, switches, and GPUs relies on fiber optic networks, with optical modules serving as the physical-layer bridge that converts electrical and optical signals. This teardown examines the Source Photonics SPQ2-8E2-8FO-COA-FB1, an OSFP-packaged 2×400G FR4 optical module compliant with IEEE 802.3ck. Total bandwidth is 800G, splittable into two independent 400G FR4 channels, with a nominal 3km single-mode transmission distance and dual duplex LC-UPC optical interfaces targeting DCI interconnects between data halls and campuses. The module uses an all-metal housing with integrated IHS grille airflow channels and hidden heat-dissipation fins, balancing EMI shielding, mechanical protection, and convection cooling for high-power OSFP operation. Inside, dual TOSA/ROSA optical assemblies connect to the PCB via FPC flex cables, with DSP, synchronous buck converters, MCU, and TEC thermoelectric controllers cooled by thermal compound. A practical reference for data center parts wholesalers and optical module buyers.
