4-port 10/100/1000BASE-T PoE + 1-port 1000BASE-X SFP + 1-port 1000BASE-T Industrial 250m PoE Switch
Industrial 250m PoE Switch Overview
The LNK-GYT411GP-SFP series is a compact, industrial-grade, four-port Gigabit PoE+ switch designed
for reliable operation in challenging environments. It features
four 10/100/1000Base-T PoE+ ports offering
a long-distance power and data transmission range of up to 250 metres, one 1000BASE-X SFP fibre slot
for long-distance backbone connections and one dedicated 1000BASE-T
copper uplink port. Designed
for security and surveillance applications, the switch offers advanced network management features,
including one-key VLAN for broadcast storm control, QoS prioritisation for critical data and robust security
protocols to prevent network attacks. Its hardened design features 6kV surge protection and a wide
operating temperature range of -40°C to 75°C, ensuring stable, secure and high-speed data transmission
for demanding applications such as industrial automation, traffic systems and outdoor monitoring.
