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

CWDM4 trades the cooled lasers of LAN-WDM for uncooled coarse wavelengths, cutting module power and cost for the short reaches that dominate data center interconnect.

Every module is coded for Cisco QSFP-100G-CWDM4-S and traffic-tested before shipment, with custom vendor coding available for mixed-vendor environments.
