The 800GBASE-SR8 OSFP optical transceiver module is designed for 800GBASE Ethernet 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 finned-top transceiver is used in Ethernet 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 Ethernet 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.
