The HPE 808722-B28 is a 30-meter InfiniBand FDR (Fourteen Data Rate) QSFP optical cable designed for high-performance cluster interconnect and data center fabric applications. Part number 808722-B28 supports bidirectional 56 Gbps throughput per direction and is compatible with HPE Apollo and ProLiant servers equipped with InfiniBand FDR adapters, as well as third-party switches and storage systems supporting QSFP optics. The V-Series designation indicates compliance with HPE's quality and interoperability standards. Typical deployments include HPC clusters, parallel storage systems, and low-latency computing environments requiring long-distance fabric connectivity beyond standard copper cable reach. The 30-meter extended length reduces rack footprint constraints in larger installations.This refurbished unit has been tested and guaranteed to meet HPE specifications.
