Overview

EW-S3910G aggregates eight 10/100/1000M SFP fiber ports and two Gigabit RJ45 uplinks in a compact plug-and-play switch. Its full-wire-speed forwarding, broad optical reach and flexible 4.5–20VDC input make it a practical fiber edge or aggregation unit.

Eight SFP fiber ports

Use separately selected single-mode or multimode SFP modules for fiber links up to the module’s rated distance.

Two Gigabit copper uplinks

RJ45 ports auto-negotiate 10/100/1000Mbps and support MDI/MDI-X for straightforward upstream connections.

Wire-speed operation

Store-and-forward forwarding, 8K MAC entries, QoS, flow control and broadcast-storm protection keep the compact switch predictable.
