The 200G QSFP56 DAC primarily enables high-bandwidth 200G links. It supports 200G Ethernet rate and InfiniBand HDR. It provides a QSFP56-to-QSFP56 copper direct-attach solution. 200G QSFP56 DAC cables are suitable for very short links and offer a cost-effective way to establish a 200-Gigabit link between QSFP-200G ports of switches/routers within racks and across adjacent racks.
Note: The FS P/N is changed from Q56-PC02 to QSFP-200G-PC02, but the product is the same. Only the FS P/N has been changed.
