The 400GBASE LR4 OSFP optical transceiver module is designed for 400GBASE Ethernet throughput up to 10km link lengths over OS2 single-mode fiber (SMF) via duplex LC/UPC connectors. This transceiver is compliant with OSFP MSA, IEEE 802.3 bs-400GAUI-8, IEEE 802.3 cu, and CMIS4.0 standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parameters.
The single-port OSFP finned-top transceiver is used in Ethernet air-cooled switches. Featuring low latency, low power, and reliability, it supports uplink connections in spine-leaf architectures, such as from a 400G switch to a 400G switch and an 800G switch to a 400G switch. 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.
