Maintain high-density 100 GbE connectivity where short-reach optical links matter most. The Eaton Tripp Lite Series N286-100G-SR4SA is an Arista-compatible QSFP28 transceiver designed for 100GBASE-SR4 deployments over multimode fiber, using an MPO interface to support compact, parallel-optics switching environments. Built for infrastructure teams that need predictable optics performance in crowded racks, this module is suited to leaf-spine fabrics, aggregation layers, and server uplinks where port density and link stability are more important than long-distance reach. Its QSFP28 form factor aligns with modern 100 GbE platforms, helping standardize transceiver selection across compatible environments. For procurement teams, the value is straightforward: a purpose-built short-reach optic that supports high-bandwidth interconnects without overbuying distance you do not need. For operators, it simplifies deployment in multimode fiber environments where fast turn-up and consistent interoperability are essential. When the network design calls for 100 GbE at short range, this module keeps the path clean, compact, and ready for production traffic.
