Overview

The Cisco QSFP-100G-SR4-S is a hot-swappable 100 Gigabit Ethernet QSFP28 optic that drives four 25G lanes over parallel multimode fiber using an MPO-12 connector. It reaches up to 70m on OM3 and 100m on OM4, making it a workhorse choice for top-of-rack to leaf/spine 100G links inside the data center. The module is MSA-compliant and supports digital diagnostics monitoring for real-time link health. Genuine Cisco hardware sourced through an authorized partner.
