3C-LINK's 200G QSFP-DD DAC cable primarily enables high-bandwidth 200G links and supports 200G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. 200G QSFP-DD DAC cables are suitable for very short links and offer a cost-effective way to establish a 200-Gigabit link between QSFP-DD ports of switches/routers within racks and across adjacent racks. 3C-LINK currently offers passive copper cables in lengths of 0.5, 1, and 2 meters.
