2.5m (8ft) NVIDIA/Mellanox Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top Ethernet Passive Copper Twinax Cable

The 400G OSFP DAC provides an OSFP-to-OSFP copper direct-attach solution with a finned-top form factor. It is designed with ultra-low loss materials, square rings, twisted pair cable 8 wires and shell extension construction for superior mechanical properties and bending performance and used only in air-cooled switches.
Tested in actual switching systems to ensure optimal signal integrity and the best end-to-end performance, the DAC is ideal for establishing high-speed 400G connections between switches or routers within the same rack or adjacent racks over very short distances and is widely used in SDN, ML, and Cloud Computing applications.
Note："Finned-top" transceivers are now called "Integrated Heat Sink" (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.
