DIGITUS Media Converter, Multimode 10/100/1000Base-T to 1000Base-SX, Incl. PSU SC connector, Up to 0.5km

The Digitus Gigabit Media Converter DN-82120-1 converts between copper and multimode fiber links to extend network connections up to 500 meters. It supports Gigabit Ethernet data rates and uses an SC fiber connector with an 850 nm wavelength. The converter operates at a 5 V input voltage and implements IEEE 802.3 standards for reliable wired connectivity.

Advantages

The DN-82120-1 provides up to 1000 Mbit/s throughput while enabling migration from copper to fiber without replacing existing infrastructure. Its SC multimode interface and Gigabit RJ-45 port ensure high-quality signal transmission and reliable delivery over short-distance fiber links. The device is compact and supports straightforward installation for quick deployment.

Suitable for

• Extending Ethernet networks over multimode fiber up to 500 m
• Connecting copper-based switches or servers to fiber segments
• Short-distance fiber backbone links within buildings or between adjacent sites

Key specifications

• Maximum data transfer rate: 1000 Mbit/s
• Ethernet LAN (RJ-45) ports: 1 (Gigabit Ethernet)
• Fiber ports quantity: 2 (SC multimode)
• Maximum transfer distance: 500 m (850 nm, multimode)
• Input voltage: 5 V
• Weight: 0.2 kg
• Standards: IEEE 802.3

How to use

Install the converter near the copper device and connect the RJ-45 port to your switch, router, or server using a Cat5e/6 cable. Attach an SC multimode fiber cable to the fiber port and route it to the remote fiber endpoint. Power the unit with a compatible 5 V supply. The converter negotiates link speed automatically and forwards traffic between the copper and fiber interfaces.

Recommendations

Place the media converter in a dry, ventilated location and use quality multimode fiber and certified Ethernet cables. Verify fiber polarity and connector cleanliness before operation. For distances close to the 500 m limit, confirm link performance with appropriate testing tools.
