Industrial Gigabit PoE Switch 4×30W Ports + SFP 250m Extended Range
Product Overview:
The LNK-GYT204GP-SFP Industrial Gigabit PoE+ Switch delivers 250m extended-range connectivity with 4×10/100/1000BASE-T PoE+ ports and 2×1000BASE-SFP fiber slots, designed for demanding industrial and surveillance applications.
Key Features & Benefits:
✅ Extended-Range Gigabit PoE+ Power
4× Gigabit PoE+ ports (IEEE 802.3at/af compliant) transmit data and 30W power up to 250 meters
Supports high-power devices like PTZ cameras, WiFi 6 APs, and industrial sensors
✅ High-Speed Fiber Connectivity
2× 1000BASE-SFP slots support single-mode (up to 120km) and multi-mode fiber
Enables noise-immune backbone links for critical infrastructure
✅ Industrial-Grade Reliability
6kV surge protection and static shielding for harsh environments
Wide temperature range (-40°C to 75°C) for outdoor installations
DIN-rail or wall-mountable rugged metal housing
✅ Advanced Network Management
One-key VLAN mode simplifies network segmentation
QoS prioritization ensures smooth video transmission
Storm control prevents network congestion
Applications:
Large-scale surveillance systems (airports, smart cities)
Industrial automation networks (factory floors, remote sites)
Transportation infrastructure (highways, rail systems)
250m Long-Distance Transmission: Ideal for large-area surveillance and outdoor wireless AP deployments (10Mbps at max range).
4× Gigabit PoE+ Ports (IEEE 802.3at): Deliver 30W per port to power PTZ cameras, WiFi 6 APs, and industrial IoT devices.
Auto MDI/MDIX & Auto-Negotiation: Simplifies installation with plug-and-play copper connectivity.
2× 1000BASE-SFP Slots: Support single-mode (120km) or multi-mode fiber (550m) for backbone links.
Jumbo Frame (9KB): Optimizes throughput for 4K video streaming and large data transfers.
Dual Power Inputs (12~48VDC): Ensure 24/7 uptime with redundant PSU support.
6KV Surge Protection & Wide Temp (-40°C~80°C): Withstands lightning strikes and extreme environments.
DIN-Rail/Wall-Mount Design: Compact metal housing for harsh industrial installations.
802.3x Flow Control: Prevents packet loss in high-density surveillance networks.
QoS Prioritization: Ensures low latency for real-time video and VoIP traffic.
