The 800GBASE 2x FR4 OSFP optical transceiver module is designed for 800GBASE Ethernet throughput up to 2km link lengths over OS2 single-mode fibre (SMF) via dual duplex LC/UPC connectors. This transceiver is compliant with IEEE 802.3ck, IEEE 802.3cu, OSFP MSA standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parametres.
The twin-port OSFP closed 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 centres.
Note: This "Closed Finned Top" refers to a closed top design, which uses a finned-top but with a lid on top of the fins creating a closed channel for additional cooling. It is engineered to support both airflow cooling and liquid-cooled environments, offering enhanced mechanical protection and thermal compatibility in high-density systems.
