Cisco QSFP-40G-SR4-S= Transceiver Module – 40GBASE-SR4 S-Class 850nm MPO-12
The Cisco QSFP-40G-SR4-S= is a Cisco S-Class 40GBASE-SR4 QSFP transceiver module designed for high-speed 40 Gigabit Ethernet connectivity over parallel multimode fiber. It operates at 850nm and uses a 12-fiber MPO/MTP multifiber interface.
The S-Class module is optimized for enterprise and data center 40GbE deployments, supporting link lengths of up to 100 meters on laser-optimized OM3 and 150 meters on OM4/OM5 multimode fiber. Unlike the standard QSFP-40G-SR4, the S-Class QSFP-40G-SR4-S does not support 4x10G breakout connectivity.
