Industrial 6-port 10/100Base-T + 3-port 100BASE-FX Ethernet Switch
Product Overview:
The LNK-IMC306 Series is a rugged industrial-grade Fast Ethernet
switch designed for reliable connectivity in harsh operating
environments. It features 6× 10/100Base-TX RJ45 copper ports and 3×
100Base-FX fiber optic ports, providing flexible network
integration for both electrical and optical transmission
requirements.
The copper interfaces support auto-negotiation, full/half-duplex
operation, and auto MDI/MDI-X, ensuring seamless plug-and-play
integration with IP cameras, wireless access points, and other
network equipment. The fiber ports offer compatibility with both
single-mode and multi-mode fiber (1-core or 2-core options),
enabling extended-distance communication up to several kilometers
with strong EMI resistance.
Built with a hardened industrial design, this switch is an ideal
solution for applications such as factory automation, intelligent
transportation systems, outdoor surveillance, and remote site
networking. Its wide operating temperature range, DIN-rail mounting
capability, and fanless construction make it suitable for
deployment in control cabinets, roadside cabinets, and other
demanding environments where reliability and ease of installation
are critical.
Features
✅ Hybrid Port Configuration: Features 6× 10/100Base-TX RJ45 copper ports and 3× 100Base-FX
fiber optic interfaces, enabling flexible integration of both
electrical and optical network segments.
✅ Intelligent Auto-Negotiation Ethernet Ports: All RJ45 ports support 10/100Mbps speeds, full/half-duplex mode,
auto MDI/MDIX, and auto-negotiation for plug-and-play operation
with IP cameras, sensors, and access points.
✅ Multi-Interface Fiber Connectivity: The 100Base-FX ports offer optional SFP, SC, FC, or ST fiber
connectors, compatible with both single-mode and multi-mode fiber
for reliable long-distance data transmission.
