Industrial 4-port 10/100/1000BASE-T + 2-port 1000BASE-SFP 250m PoE Switch
Industrial 250m Gigabit PoE Switch Overview
The LNK-GYT204GP-SFP series is a high-performance industrial PoE+ switch featuring
four 10/100/1000Base-TX PoE+ ports (30 W per port) and two 1000Base-SFP fibre uplink ports.
It supports both single-mode and multi-mode fibre for long-distance connectivity of up to 250 m.
Designed for demanding surveillance and industrial applications, the switch delivers power and data over
a single RJ-45 cable to IP cameras, wireless access points (APs), and other powered devices (PDs),
while ensuring fast packet forwarding and high bandwidth for crystal-clear video transmission.
Built for harsh environments, it includes advanced surge protection and static defence circuits
for maximum reliability. Key features such as one-key VLAN mode, QoS prioritisation,
broadcast storm control and network security protection make it ideal for mission-critical
surveillance systems and industrial IoT deployments.
