## Summary description

The InLine Network Media Converter 10/100/1000Mb/s TP to SFP FO, SM, 20km enables seamless data transfer with a maximum rate of 1000 Mbit/s. It features a 100Base-TX and 1000Base-TX input interface, and a 1000Base-FX output interface. With a single-mode fiber optic connector (SFP) and a maximum transfer distance of 20 km, it operates at a wavelength of 1310 nm. The device is equipped with LED indicators for activity, power, and status, and is certified by FCC. It operates on a 5V input voltage and 1A input current.

## Long description

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
Key specifications
Model: InLine 66659D
Data rate: up to 1000 Mbit/s (10/100/1000 Mbps)
Ports: 1 × RJ45 (10/100/1000Base-T), 1 × SFP (1000Base-FX, LC duplex)
Fiber type: Single-mode (SM), wavelength 1310 nm
Maximum fiber distance: 20 km
LEDs: power, link/activity, status
Power input: 5 V, 1 A
Colour: Black
Certifications: FCC
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.
Usage 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.
