Cisco QSFP-100G-SR4-S Compatible 100GBASE-SR4 QSFP28 850nm 100m OM4 DOM MPO-12 Parallel MMF Optical Transceiver Module, 4x 25G-SR

100G QSFP28 SR4 optical transceiver

This 100GBASE-SR4 QSFP28 module is the standard short-reach choice for spine-leaf fabrics and high-density switching. Four parallel 25G lanes run over an MPO-12 multimode trunk, reaching 100 meters on OM4 fiber, and the unit is coded and burn-in tested to behave exactly like the Cisco QSFP-100G-SR4-S in production networks.

The transmitter uses 850nm VCSEL arrays with a multimode receiver on the same MPO-12 interface. Digital optical monitoring exposes per-lane transmit power, receive power, temperature and voltage through the standard I2C interface, so operations teams can watch link health in real time. The module also supports 4x25G breakout when paired with MPO to LC harness cables, making it a flexible building block for mixed-speed data centers.
