DLINK DMC-820SSC 100/1000 Twisted-pair to Single-mode fiber Smart Media Converter (20km) | 790169002600

The D-Link DMC-820SSC (790169002600) is a critical infrastructure component for organizations needing to extend their Ethernet reach far beyond the standard 100-meter copper limitation. This "Smart" media converter transforms 10/100/1000BASE-T RJ45 signals into 1000BASE-LX single-mode fiber signals. It is an ideal tool for connecting remote buildings, security perimeters, or rural office branches to a central network backbone with minimal signal degradation.

Key Features
A standout feature of the DMC-820SSC is its "Smart" functionality, which includes Link Pass Through and Far End Fault detection. These protocols ensure that if one link segment fails, the converter automatically shuts down the other link, allowing network administrators to identify and troubleshoot cable breaks instantly. The unit utilizes a standard Duplex SC fiber connector and supports full-duplex flow control to prevent data loss during high-traffic periods.

Performance / Technology
Equipped with a powerful optical transceiver, the DMC-820SSC operates at a 1310nm wavelength, capable of pushing Gigabit data up to 20km (12.4 miles) over single-mode fiber. The RJ45 port features Auto-MDI/MDIX, eliminating the need for crossover cables, and automatically negotiates between 100 Mbps and 1000 Mbps speeds to match your existing hardware. This ensures a "plug-and-play" experience while maintaining the lowest possible latency for mission-critical data streams.

Design & Ergonomics
The DMC-820SSC is housed in a durable, compact metal casing that can be used as a standalone desktop unit or installed in the D-Link DMC-1000 chassis for centralized power management. The front panel features a comprehensive set of diagnostic LEDs for Power, Link/Activity, Full-Duplex, and Speed, providing immediate visual feedback. Its fanless design ensures silent operation and high reliability in environments where dust or noise may be a concern.

Compatibility / Use Cases
This media converter is the definitive choice for telecommunications providers, large manufacturing plants, and university campuses. It is fully compatible with standard single-mode fiber optic cabling and Gigabit Ethernet switches from any manufacturer. Whether you are extending a 4K IP surveillance feed from a remote gate or linking two separate office wings, the DMC-820SSC provides the stable, long-distance foundation required for modern fiber integration.

Why This Product Stands Out
The D-Link DMC-820SSC stands out for its unique "Smart" link features which are often missing in basic, unmanaged converters. While cheaper models might leave a network "blind" to a fiber break, the DMC-820SSC ensures your managed switches stay informed of the link status. Its 20km range and dual-speed support (100/1000) make it a future-proof investment for networks transitioning from Fast Ethernet to full Gigabit fiber speeds.
