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

100G QSFP28 CWDM4 optical transceiver

The 100GBASE-CWDM4 QSFP28 module is the economical answer for 100G links up to 2 kilometers on existing single-mode fiber pairs. Four coarse wavelengths, 1271, 1291, 1311 and 1331nm, share one duplex LC connection, so no MPO re-cabling is needed when migrating from duplex 10G or 40G infrastructure.

Because uncooled CWDM lasers need no temperature control, the module runs at notably lower power than LAN-WDM designs, which matters in dense chassis. It complies with IEEE 802.3bm, the 100G CWDM4 MSA, SFF-8665, SFF-8636 and ITU-T G.694.2, and provides DOM monitoring of all four channels. The unit is coded for Cisco QSFP-100G-CWDM4-S and verified on major switching platforms used across UAE data centers.
