D-Link DMC-300SC Multimode Media Converter

The D-Link DMC-300SC is a reliable media converter designed to seamlessly connect 10BASE-T/100BASE-TX copper networks to 100BASE-FX multimode fiber optic systems. Supporting IEEE 802.3 and 802.3u standards, this converter uses an SC-type connector and operates at full wire-speed with shortwave laser technology. Ideal for extending network distances up to 2 kilometers over multimode fiber, the DMC-300SC is a versatile standalone device with features such as Auto MDI/MDI-X and auto-negotiation of speed and duplex settings to simplify installation and enhance network performance.

Product Features

Seamless Copper to Fiber Conversion

Connect traditional twisted-pair copper networks to fiber optic cabling with the DMC-300SC, enabling extended network reach and improved signal integrity for 10/100 Mbps Ethernet applications.

Support for Multimode Fiber

Designed for multimode fiber cables with SC connectors, this converter supports fiber transmission distances up to 2 kilometers, suitable for enterprise and campus networking environments.

Auto Negotiation and MDI/MDI-X Support

The device automatically detects the required speed and duplex mode on the copper interface, while Auto MDI/MDI-X eliminates the need for crossover cables, simplifying setup and compatibility.

Standalone Operation

The DMC-300SC operates independently without the need for a chassis, offering flexibility for various network setups and easy deployment in existing infrastructures.

LED Status Indicators

Front panel LEDs provide real-time information about power, link/activity, speed, and duplex/collision status, making network monitoring and troubleshooting straightforward.
