MMA1L30-CM Mellanox 100Gbps 100GBase-CWDM4 Optical Transceiver Module
MMA1L30-CM Overview
The is a Mellanox (NVIDIA) 100G QSFP28 CWDM4 optical transceiver, designed for high-speed transmission over single-mode fiber up to 2 km.It uses CWDM (Coarse Wavelength Division Multiplexing) technology, where 4 optical signals (each 25Gbps) are combined onto a single duplex LC fiber pair, enabling efficient 100Gbps communication over standard SMF infrastructure.Unlike PSM4 modules (which use MPO and parallel fibers), this module uses a duplex LC connector, making cabling simpler and more common in enterprise environments.
