## Long description

The Digitus Gigabit Media Converter DN-82121-1 converts copper Ethernet signals to single-mode fiber and back, enabling network extension up to 20 km without replacing existing infrastructure. It supports up to 1000 Mbit/s and features a 1000Base-TX RJ-45 port and a 1000Base-LX SC fiber output operating at 1310 nm. LED indicators show activity, link and status for simple monitoring and the device runs on a 5 V supply.
Advantages
The converter delivers gigabit performance over long distances with a compact, black enclosure and SC fiber connector. It supports auto-negotiation for 10/100/1000 Mbit/s on the copper port, provides reliable signal transmission up to 20,000 m on single-mode fiber, and includes LEDs for quick operational checks. Its plug-and-play design enables straightforward installation without complex configuration.
