Cisco QSFP-100G-CWDM4-S Compatible 100GBASE-CWDM4 QSFP28 1310nm 2km OS2 DOM Duplex LC SMF Optical Transceiver Module

For migrations from duplex 10G or 40G infrastructure, CWDM4 is the gentle path: the same fiber pairs, the same LC connectors, now carrying 100G.
The 100G signal travels over wavelengths at 1271, 1291, 1311 and 1331nm, multiplexed onto a duplex LC fiber pair. Because uncooled CWDM lasers need no temperature control, module power stays notably lower than LAN-WDM designs.
