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.
