NVIDIA/Mellanox Compatible 400GBASE-VSR4 OSFP IHS/Finned Top 8 x 50G PAM4 850nm 50m MPO-12/APC MMF Ethernet Transceiver Module

The NVIDIA/Mellanox Compatible OSFP optical transceiver module is designed for 400GBASE Ethernet throughput up to 50m link lengths over OM4 multimode fibre (MMF) using a wavelength of 850nm via MTP/MPO-12 APC connectors. This transceiver is compliant with CMIS 5.2, IEEE 802.3bs, IEEE 802.3db and OSFP MSA standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parametres.
The single-port OSFP finned-top transceiver is designed for Ethernet air-cooled switches, delivering low latency, low power consumption, and high reliability. It supports uplink connections in spine-leaf architectures, such as from an 800G switch to a 400G switch, as well as downlink connectivity from top-of-rack switches to Ethernet network adapters. It is the ideal solution for HPC computing, AI, and cloud data centres.
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.
