800G OSFP DAC (Passive Direct Attach Copper) enables highbandwidth 800G links and supports 800G Ethernet rate. It provides an OSFP copper direct-attach solution. This cable is compliant with OSFP MSA (Multi-Source Agreement), IEEE 802.3ck and 400GBase-CR4 standards. This direct attach copper twinax cable is suitable for short-distance connectivity within a rack or between adjacent racks in data centers. 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 is high-speed, cost-effective alternatives to OSFP optical modules in 800G Ethernet applications. It meets OSFP800 MSA, IEE802.3ck, 400GBaseCR4 standards. These high performance 800G OSFP-to-OSFP copper direct-attach cables are offered in lengths of 1, 1.5, and 2 meters.
