Ruckus E100G-QSFP28-ER4L 100GBASE-ER4 QSFP28 | SMF, 40 km, Enterprise

Move 100 Gigabit Ethernet farther without changing the architecture. The Ruckus E100G-QSFP28-ER4L is a QSFP28 optical module designed for 100GBASE-ER4 LTE deployments over single-mode fiber, with support for 40 km links and FEC. That combination makes it well suited to long-reach connections where optical budget and link stability are critical. This module fits enterprise backbones, campus interconnects, and other environments where high-speed transport must span meaningful distance. Compared with short-reach optics, ER4-class modules are chosen when the network design calls for more reach and fewer compromises. That matters when you are connecting buildings, extending aggregation layers, or maintaining 100 GbE service across distributed infrastructure. For procurement teams and architects, the value is clear: the right long-reach optic reduces redesign risk and keeps the network aligned with the physical plant. It is a targeted component for infrastructure that needs both speed and distance, without stepping down from 100 GbE performance.
