Mellanox MMS1V50-WM Compatible 400G QSFP-DD FR4 PAM4 8 LWDM Optical Transceiver Module ( CWDM/DWDM SMF LC 2km DDM with FEC)
Mellanox MMS1V50-WM Compatible QDD FR4 is an advanced 400 Gigabit Ethernet (IEEE 802.3bs) transceiver that uses Long Wavelength Division Multiplexing (LWDM8) to transmit data over SMF (single-mode fiber) at speeds up to 400 Gbps. It supports eight channels of 50G 400GAUI-8 PAM4 (Pulse-Amplitude Modulation) over distances of up to 2 km using four wavelengths - 1271 nm, 1291 nm, 1311 nm, and 1331 nm. Additionally, the QDD FR4 supports Forward Error Correction (FEC) to help ensure reliable data transmission.
