NVIDIA/Mellanox Compatible 400GBASE-FR4 OSFP IHS/Finned Top 8 x 50G PAM4 1310nm 2km Duplex LC/UPC SMF Ethernet Transceiver Module

The NVIDIA/Mellanox Compatible OSFP optical transceiver module features a duplex LC connector and supports transmission up to 2km over parallel single-mode fibre. The 400 Gigabit Ethernet signal is carried over four parallel 1310nm optical lanes by one wavelength per lane. It can be interoperable with other IEEE-compliant 400GBASE-LR4 interfaces. And It is compliant with OSFP MSA, IEEE 802.3bs, IEEE 802.3cu.
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 connectionsin spine-leaf architectures, such as from an 800G switch to a 400G switch. It is the ideal solution for HPC computing, AI and cloud datacentres.
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.
