The 800GBASE-SR8 OSFP IHS/Finned Top optical transceiver module is designed for 800GBASE network throughput up to 50m link lengths over OM4 multimode fiber (MMF) using a wavelength of 850nm via dual MTP/MPO-12 APC connectors. This transceiver is compliant with IEEE 802.3ck, OSFP MSA standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parameters.
The twin-port OSFP IHS/Finned Top transceiver is used in air-cooled switches. Featured with low latency, low power, and reliability, it can link upward in spine-leaf architectures for switch-to-switch applications, downward for top-of-rack switch links to network adapters, and/or to BlueField-3 DPUs in compute servers and storage subsystems. It is the ideal solution for HPC computing, AI, and cloud data centers.
Note: "Finned-top" transceivers are now called "Integrated HeatSink" (IHS) as the cooling fins are integrated into the OSFP connector metal top. Commonly used in air-cooled switches. "Flat-top" transceivers are now called "Riding Heat Sink" (RHS) as the cooling fins ride on top of the network card or systems internal cages. This is used for both air-cooled and liquid-cooled applications for DGX, ConnectX-7, and BlueField-3 DPUS.
