3. Description

The QSFP28 CWDM4 is a Four-Channel, Pluggable, dual LC, Fiber-Optic QSFP28
Transceiver for 100G Ethernet applications. The QSFP28 full-duplex optical module offers
4 independent transmit and receive channels, each capable of 26Gbps operation for an
aggregate data rate of 104Gbps 2km using single mode fiber. These modules are designed
to operate over single mode fiber systems using 1271nm-1331nm DFB laser array. QSFP28
CWDM4 is one kind of transceiver which provides increased port density and total system
cost savings. They are compliant with the QSFP28 MSA, CWDM4 MSA and portions of
IEEE P802.3bm.
