The 100g qsfp28 er-CWDM4-2km module is a highly integrated 4x28G transceiver focused on reach, bandwidth, density and cost for high port-count 100G systems, and client-side 100G interfaces. It is compliant with the 100G 4WDM-10 MSA, which is based on the CWDM4 MSA version 1.1. It is interoperable with 100g cwdm4 transceivers over a 2 km reach.
