Build higher-capacity uplinks without changing the physical model of your network. This QSFP28 SR4 transceiver delivers 100 GbE over multimode fiber using 850 nm optics and an MPO connector, making it a practical fit for short-reach data center and enterprise aggregation layers. The module is aimed at environments where bandwidth growth has to happen inside the rack, row, or adjacent room. Its SR4 parallel optics architecture supports dense switch interconnects while keeping fiber management straightforward. For teams standardizing on Cisco-compatible optics, it offers a clean way to expand 100G capacity while staying aligned with existing infrastructure patterns. Choose this transceiver when you need short-distance 100G transport with the port density and optical simplicity that multimode deployments demand. It is built for teams that value compatibility, operational clarity, and a measured path to higher throughput.
