InLine verkkomediakonvertteri 10/100/1000 Mb/s TP–SFP kuitu, SM, 20 km

The InLine Media Converter 66659D converts copper Ethernet (RJ45) to single-mode fiber (SFP, LC duplex) to extend or migrate existing networks with a maximum data rate of 1000 Mbit/s. Compliant with IEEE 802.3 standards, it provides one 10/100/1000Base-T RJ45 port and one SFP slot for 1000Base-FX single-mode connections up to 20 km at 1310 nm. The compact black housing is suitable for desktop installation and allows administrators to connect remote segments or link buildings without changing existing copper cabling.

Advantages

The converter supports Gigabit and Fast Ethernet speeds and ensures transparent protocol conversion between TP and fiber links. Its SFP socket enables flexible choice of fiber modules, while LEDs indicate power, link/activity and status for easy troubleshooting. Low power requirements (5 V / 1 A) and FCC certification make it suitable for standard network environments.

Suitable for

• Extending LAN segments over single-mode fiber up to 20 km
• Connecting separate buildings or remote floors
• Migrating from copper to fiber infrastructure without rewiring
• Integrating fiber links into existing Ethernet networks

How to use

Install a compatible single-mode SFP module (LC duplex) into the SFP slot and connect the fiber patch cable. Plug the copper Ethernet cable into the RJ45 port and connect the power supply (5 V / 1 A). After powering on, verify LED indicators to ensure link and activity. For a point-to-point link, connect two converters directly via single-mode fiber; for network integration, insert the converter at the network edge where fiber-to-copper conversion is required.

Recommendations

Use single-mode LC duplex fiber and matching SFP modules rated for 1310 nm and 20 km. Keep fiber connectors clean and observe bend-radius limits. Place the converter in a ventilated, dust-free location and ensure the power supply matches the specified 5 V / 1 A rating.
