The Cisco QSFP-40/100-SRBD Compatible 40/100GBASE-SM4 SWDM4 QSFP28 Optical Transceiver Module is designed for use in 40/100G Ethernet. In 40 Gbps mode, the transceiver supports link lengths of up to 440 meters over laser-optimized OM5 multimode fiber. In 100 Gbps mode, it supports link lengths of up to 150 meters on OM5. It operates at four different wavelengths, each supporting 10G/25G transmission over existing duplex multimode fiber with standard LC connectors. The SWDM4 transceiver enables reuse of its existing 10G duplex MMF infrastructure for migration to 40G with a path toward 100G.
