JTOPTICS® 400G QSFP56-DD AOC (active optical cable) is a 400 Gb/s parallel active optical cable, which transmits parallel 4X100 Gb/s PAM4 signals over multi-mode fiber (MMF) cables up to 100m. It is compliant with QSFP56-DD MSA and the CMIS 4.0. The 400G QSFP56-DD AOC cables supports eight electrical interface lanes, each of which operate in the data rate of 100G, with an overall aggregate bandwidth up to 425Gb/s. These modules of cables are designed to operate over multi-mode fiber systems using a nominal wavelength of 850nm.The electrical interface uses a 76 contact edge type connector. This active optical cable is compliant with IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, and QSFP-DD-CMIS-rev4p0.Hot-pluggable QSFP-DD active optical cable assemblies4x 100G PAM4 electrical interface4x 100G PAM4 optical interfaceData rate up to 100Gbps per channel.8-channels 850nm VCSEL array and PIN photo-detector arrayCompliant with QSFP-DD MSA, CMIS and IEEE 802.3Low power dissipationCompliant with IEE..
