JTOPTICS® 400G QSFP-DD to 8x50G SFP56 breakout active optical cables operate over multi-mode fibers (MMF). This breakout cable is compliant with QSFP-DD MSA/SFP28 MSA and IEEE 802.3cd Standards. Thin and lightweight AOC cables simplify cable management, enabling an efficient system airflow, which is critical in high-density racks. It is used extensively in cloud and supercomputers due to its low cost, high-value proposition, and increased reliability.JTOPTICS 400G QSFP-DD to 8x 50G SFP56 Breakout AOC (Active Optical Cable) assemblies are designed to support 400G/4x50G Ethernet and InfiniBand HDR/HDR100, suitable for data center and HPC (High-Performance Computing) links up to 100m over multi-mode fiber.Hot Pluggable QSFP-DD and SFP56 MSA Compliant8-channels 850nm VCSEL array and PIN photo-detector arrayData rate up to 53.125Gbps (26.5625GBd PAM4) per channel.400GAUI-8 electrical interfacesCompliant with QSFP-DD MSA, CMIS 4.0 and IEEE 802.3cm 400GBASE-SR8Supports 400G to 8x 50G Ethernet..
