400GBASE-FR4 QSFP112 NDR InfiniBand Single Mode PAM4 1310nm 2km DOM Duplex LC UPC

This Mellanox compatible QSFP112 NDR InfiniBand optical module is a 400Gb/s single-port QSFP112 FR4 single-mode parallel optical module, using a single 4-channel duplex LC/UPC optical connector. This short-range 4-channel (FR4) design employs 100G-PAM4 modulation to achieve transmission distances of up to 2km over OS2 single-mode fiber. This optical module is used to connect ConnectX-7/QSFP112 network cards to 2x400G IB switches with dual-port optical modules.
