Mellanox MMS1V90-WR Compatible 400G QSFP-DD LR4 PAM4 CWDM4 lanes MUX/DEMUX design 10km LC SMF FEC DDM/DOM Optical Transceiver Module (1271nm 1291nm 1311nm 1331nm)
Mellanox MMS1V90-WR Compatible QSFP-DD SR8 400G Ethernet Optical Transceiver Module from QDD is the perfect solution for high-speed data center applications. It supports up to 400G of bandwidth over a single channel with up to 10km reach. This module features a Quad Small Form-Factor Pluggable – Double Density (QSFP-DD) form factor with 4 CWDM4 lanes and 4-level Pulse Amplitude Modulation (PAM4) encoding. The optical transceiver uses a wavelength range of 1271 to 1331nm and is compliant with the Multi-Source Agreement (MSA) standard. NADDOD's QSFP-DD LR4 is ideal for high-speed data transfers in data centers and Infiniband networks.
