100G-ESR4-QSFP300M — Module QSFP28 100 Gbps Extreme Networks — 100 Gb ESR4 QSFP28 Module

The Extreme Networks 100G-ESR4-QSFP300M is a QSFP28 100 Gbps ESR4 transceiver for multimode fibre, covering 70 to 100 m via MPO connector. ESR4 technology extends reach compared to standard SR4 modules over OM3/OM4 fibre while retaining the high-density MPO cabling suited to datacenter environments. This module integrates with the QSFP28 ports of Extreme Networks equipment.

It is suited to short-reach top-of-rack and spine-leaf links requiring MMF MPO cabling, typically in rooms where the distance between devices does not exceed 100 m. Its ESR4 designation distinguishes it from BiDi LC modules (10407) oriented towards reuse of existing cabling. Genuine Extreme Networks hardware, manufacturer warranty.
