Digitus DN-82123 médiakonverter

The Digitus DN-82123 is a bidirectional gigabit media converter that enables conversion between copper Ethernet (RJ45) and single-mode fiber (SC) for long-distance connections up to 20 km. It supports 10/100/1000Base-TX on the copper side and 1000Base-LX on the fiber side with a wavelength of 1550 nm, offering a compact and energy-efficient 5 V device with 2.5 W power consumption.

Advantages

The media converter provides reliable data transmission at gigabit speeds with a maximum throughput of 1000 Mbit/s and low power consumption. Its single RJ45 port and single SC fiber port simplify point-to-point link setups while maintaining signal integrity over distances up to 20,000 m. The compact, black housing and straightforward operation make installation and integration into existing networks quick and uncomplicated.

Suitable for

• Extending Ethernet networks over long distances via single-mode fiber
• Connecting copper-based switches or routers to fiber backbone segments
• Migrations from copper to fiber without replacing existing network devices
• Point-to-point links in office buildings, campuses, or industrial sites

How to use

Connect the RJ45 port of the Digitus DN-82123 to your Ethernet device (switch, router or NIC) and the SC fiber port to the single-mode fiber link. Ensure the transmit/receive orientation on the fiber connection is correct and secure the connectors. Apply the supplied 5 V power adapter and verify link LEDs to confirm successful establishment of the gigabit connection. For a reverse direction link, install a second compatible media converter at the far end of the fiber span.

Recommendations

Use the converter with single-mode SC fiber and appropriate transceiver fiber specifications (1550 nm) for distances approaching 20 km. Place the device in a dry, ventilated location and avoid exposure to extreme temperatures. Test link speed and stability after installation to confirm gigabit operation.
