## Long description

The DIGITUS Media Converter DN-82021-1 converts 100Base-TX (copper) to 100Base-FX (fiber), allowing transmission of Fast Ethernet signals over single-mode fiber up to 20 km. Compliant with IEEE 802.3 and IEEE 802.3u standards, this compact black unit uses an SC fiber connector and operates at a wavelength of 1310 nm. It is powered by 5 V with low power consumption (approx. 2.5 W) and includes LED indicators for activity, link and status to assist with monitoring.
Advantages
The converter provides reliable long-distance data transfer up to 20,000 m while preserving Fast Ethernet performance. Its compliance with established IEEE standards ensures interoperability with existing network equipment. The device is compact, energy-efficient and equipped with status LEDs for easy troubleshooting. Link Fault Pass Through functionality aids network diagnostics by propagating link failures to connected devices.
Suitable for
 Extending Fast Ethernet links over single-mode fiber up to 20 km
 Migrating copper-based network segments to fiber without replacing existing switches
 Connecting distant network devices in campus, industrial or telecom environments
Key specifications
 Model: DIGITUS DN-82021-1
 Ethernet: 1 × RJ-45 (10/100 Mbps)
 Fiber: 1 × SC (100Base-FX), wavelength 1310 nm
 Maximum transfer distance: 20,000 m (single-mode)
 Power: 5 V, approx. 2.5 W
 Indicators: Activity, Link, Status
 Colour: Black; Weight: 0.2 kg
How to use
Connect the RJ-45 port to the copper Ethernet device (switch, router or NIC) and insert the single-mode SC fiber cable into the SC fiber port. Apply the 5 V power supply and verify LED indicators for link and activity. The converter operates transparently and requires no software configuration; data is forwarded between the copper and fiber interfaces at Fast Ethernet speeds.
Usage recommendations
Install the converter in a dry, ventilated location and use single-mode SC fiber rated for 1310 nm. Keep fiber connectors clean to maintain signal quality. Use Link Fault Pass Through during troubleshooting to quickly locate link issues, and ensure connected devices support 10/100 Mbps operation.
