The Cisco 400G QDD-4ZQ100-CUxM passive copper cable enables high-bandwidth breakout from a 400G port to four QSFP56 100GE links. It provides a QSFP-DD-to-4x QSFP56 100GBASE-CR2 copper direct-attach solution. QDD-4ZQ100-CuxM cables are suitable for very short links and offer a cost-effective way to establish a 4x 100-Gigabit link between a QSFP-DD 400G port and four 100GE ports on switch or servers within or between adjacent racks. Cisco currently offers 400G QDD-4ZQ100-CUxM passive copper cables in lengths of 1, 2, 2.5, and 3 meters. FEC is performed on the host platform.
