The Cisco FET-40G QSFP module is a fabric-extender transceiver module used to connect to fabric links between the fabric extender switch and the parent switch. It operates over parallel multimode fiber (MMF) at 850 nm. It supports native 40G optical links over 12-fiber ribbon cables with MPO/MTP connectors or can be used in 4x10G mode with parallel-to-duplex fiber breakout cables for connectivity to four FET-10G interfaces. Distances supported are up to 100 meters on laser-optimized OM3 fiber and up to 150 meters on OM4/OM5 multimode fiber cables. It is a Quad Small Form-Factor Pluggable (QSFP+) module with an MPO-12 connector type and a power consumption of 1.5W. It features 4 independent transmit and receive channels, each capable of 10Gbps operation for an aggregate data rate of 40Gbps. It is compliant with QSFP+ MSA (SFF-8436) and supports DDM/DOM optical diagnostics.
