Solid QSFP eSR4 optic.
The QSFP-40G-eSR4 is a QSFP+ form-factor 40GBase-eSR4 multimode optical transceiver module using 850 nm VCSEL technology and an MPO connector to deliver 40 Gbps aggregated bandwidth across four 10 Gbps lanes.
It is ideal for high-density, short-reach connectivity in data center interconnects, switch-to-switch links, blade server farms and SAN/NAS architectures requiring 40 Gbps Ethernet over multimode fiber.
It supports OM3/OM4 multimode fiber and uses a 12-fiber MPO (Multi-Fiber Push On) female connector for simultaneous four-lane transmission.
This module reliably transmits up to 300 meters over OM3 multimode fiber and up to 400 meters over OM4, meeting 40GBase-eSR4 specifications.
