Industrial 1-Port PoE+ to 4-Port Gigabit PoE Extender 400m Cascade
Overview
The LNK-IPE104-30 is an industrial-grade PoE extender that converts one 802.3at PoE+
input into four PoE outputs. It extends both power and data transmission up to 200m per
unit, with daisy-chain support of up to three devices for a total reach of 400m. Ideal for
multi-point deployments in surveillance, wireless AP, and IoT networks without additional
cabling or power adapters.
Features
1-to-4 PoE Extension – Expands a single PoE+ input into four PoE outputs
Long-Distance Power & Data – Extends Ethernet and PoE up to 200m per unit
Cascade up to 3 Units – Achieve a total PoE+ reach of 400m (1312 ft.)
High Power Support – Delivers up to 25.5W shared budget across 4 ports
Industrial Durability – IP40 aluminum housing, -40°C to 80°C operation
Plug-and-Play Deployment – No external power adapter required
Robust Protection – 6KV surge and 8KV ESD immunity for field reliability
