Know before you buy
This cable is designed for short-reach, high-speed data transmission between network devices, such as connecting switches or servers within the same rack. It provides a reliable, low-latency copper connection for 50G networking environments.
No, this cable is specifically designed for SFP56 ports. While physical form factors can sometimes be similar, SFP56 is engineered for 50G data rates and is not backward compatible with the lower-speed standards of SFP+ or SFP28.
DAC cables are a more cost-effective and power-efficient solution for short-distance connections, typically under 2 meters. Because they are pre-terminated and use copper, they eliminate the need for separate transceivers and fiber patch cables, simplifying your setup.
This cable measures 0.65 meters, which is approximately 2.13 feet. This length is ideal for top-of-rack deployments where devices are located in close proximity.
No, this is a passive, pre-terminated cable that is ready for immediate deployment. Simply plug the SFP56 connectors into your compatible network devices, and the link should establish automatically.
