800G OSFP DAC (Passive Direct Attach Copper) enables high-bandwidth 800G links and supports 800G Ethernet rate. It is high-speed, cost-effective alternatives to OSFP optical modules in 800G Ethernet applications. The 800G OSFP DAC cable contains 16 (8 transmitting and 8 receiving) high-speed copper pairs, each operating at data rates of up to 106.25Gb/s, which are suitable for very short links and offer a cost-effective and power-efficient way to establish a 800-Gigabit link between OSFP ports of switches/routers within racks and across adjacent racks. The 800G OSFP DAC assembly meets OSFP800 MSA, IEE802.3ck, 400GBase-CR4 standards. AscentOptics provide high performance 800G OSFP-to-OSFP copper direct-attach cables in lengths of 1, 1.5, and 2 meters.
