10Gtek® QSFP28 active optical cables (AOC) are high-performance active optical cables with bi-directional signal transmission and aggregate 100-Gbps bandwidth for both Infiniband EDR and Ethernet 100G-SR4 applications. Compared to conventional copper cables, longer and lighter optical cables enable the ease of complicated data-center cablings. The AOCs utilize multimode fiber with 850-nm VCSELs and PIN PDs. The certificated cables have superior signal integrity and bit error rate, which enables reliable operation performance.
