JTOPTICS® 400G QSFP-DD Breakout AOC (Active Optical Cable) assemblies include 400G QSFP-DD to 4x 100G QSFP56 breakout AOC. The module integrates eight parallel lanes on 400G end and fan-out to four parallel lanes on each 100G end. Each lane operate 53.125Gb/ps PAM4 modulation signal. These 400G parallel breakout Active Optical Cable (AOC) assemblies transmit parallel 8x 50G PAM4 signals over multi-mode fiber (MMF) cables up to 100m. Compliant with QSFP-DD/SFP MSA and CMIS 4.0. they are designed with high performance, high density and low power, which are suitable for short range interconnection for data center, high-performance computing networks,Hot-pluggable QSFP-DD/QSFP28 form factor full-duplex transceiver assembly8-channels 850nm VCSEL array and PIN photo-detector arrayData rate up to 53.125Gbps (26.5625GBd PAM4) per channel400GAUI-8 and 100GAUI-2 electrical interfacesCompliant with QSFP-DD MSA, CMIS 4.0 and IEEE 802.3cm 400GBASE-SR8Compliant with InfiniBand HDR/HDR100MMF cable wi..
