D-Link DMC-300SC SC Multimode Media Converter – 10/100BASE-TX to 100BASE-FX

The D-Link DMC-300SC SC Multimode Media Converter is a reliable and cost-effective solution designed to convert standard 10/100BASE-TX Ethernet copper connections to 100BASE-FX fiber, and vice versa. Built to meet IEEE 802.3 and 802.3u standards, it utilizes SC-type connectors and supports multimode fiber transmission over distances of up to 2 kilometers. The DMC-300SC enables businesses to extend their network reach, reduce electromagnetic interference, and improve signal integrity in environments where long-distance or high-speed connectivity is critical.

Product Features

Copper to Fiber Media Conversion

The DMC-300SC allows seamless conversion between 10BASE-T/100BASE-TX copper Ethernet and 100BASE-FX fiber, enabling integration of fiber-optic cabling into legacy copper networks.

Multimode Fiber Support

Utilizes SC-type connectors and supports multimode fiber to deliver data across distances of up to 2 km, ideal for campus or building-to-building links.

Auto Negotiation and MDI/MDI-X

The twisted-pair port supports auto-negotiation of speed (10/100 Mbps) and duplex modes (half/full), along with Auto MDI/MDI-X for simplified connectivity without crossover cables.

Standalone Operation

No need for additional chassis—this media converter operates independently using an external AC power adapter, making deployment quick and flexible.

LED Status Indicators

Equipped with front panel LEDs to monitor power, link activity, duplex status, and speed, making it easier to manage and troubleshoot connections.
