40GB-ESR4-QSFP — Module QSFP+ 40 Gbps Extreme Networks — 40 Gb ESR4 QSFP+ Module

The 40GB-ESR4-QSFP transceiver from Extreme Networks delivers 40 Gbps in QSFP+ form factor over multimode fiber (MMF), with an MPO interface and a reach of 70 to 100 meters depending on fiber quality. The ESR4 profile of this module differentiates it from standard SR4 variants through its tolerance for slightly degraded MMF infrastructures or marginally longer distances on OM3.

It is suited to datacenter architectures that require a robust 40G MMF MPO module, particularly for connections between servers and ToR switches or bay interconnects. Its Extreme Networks certification guarantees optimal interoperability with the brand's equipment range. Genuine Extreme Networks hardware, manufacturer warranty.
