The Arista QSFP-100G-SR4 is a high-performance 100GBASE-SR4 QSFP28 optical transceiver designed for short-reach 100 Gigabit Ethernet applications over multimode fiber. Supporting link lengths of up to 70 meters over OM4 multimode fiber, this transceiver delivers reliable, low-latency connectivity ideal for high-density data center environments, top-of-rack switching, and hyperscale network deployments.



Fully compatible with Arista switches and routers, the QSFP-100G-SR4 uses a 4-lane parallel optical interface operating at 25 Gbps per lane to achieve an aggregate bandwidth of 100 Gbps. Whether you're building out a spine-leaf architecture or upgrading your core data center fabric, this optic delivers the performance and reliability you need.
