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

Our 100G QSFP28 SR4 combines 850nm VCSEL arrays with per-lane diagnostics, giving operations teams full visibility into each of the four channels that make up the 100G link.

Beyond native 100G mode, the module supports 4x25G breakout when paired with MPO to LC harness cables, making it a flexible building block for mixed-speed rows. Compliance with IEEE 802.3bm and the QSFP28 MSA guarantees interoperation with standards-based equipment.
