Mellanox QMMA1U00-WS Compatible 400G QSFP-DD SR8 PAM4 Optical Transceiver Module (850nm MTP/MPO OM3/OM4 100m with FEC DDM)

Mellanox QMMA1U00-WS Compatible 400G SR8 QSFP-DD Transceiver Module is designed with 4x 50Gb/s PAM4 modulation for up to 100m over OM4 transmission multimode fiber. The Transceiver supports eight electrical interface channels that operate in 50G PAM4 coding mode to produce 400G (8x50G) data rates. It is compliant with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard. The multiplexing and demultiplexing of eight wavelengths are managed within the device and connect 400G signals from the server side (NIC) to the data center aggregation switch.
