The DMC-300SC by D-Link® is a media converter designed to connect 10BASE-T/100BASE-TX copper to 100Base-FX fiber media and vice versa. Based on the IEEE 802.3 and 802.3u standards, the DMC-300SC is designed for use with multimode fiber cable utilising the SC-Type connector. The DMC-300SC supports shortwave (SX) laser specifications at a full wire-speed forwarding rate. Other features of this module include the ability to be used as a standalone device (no chassis required), Auto MDI/MDI-X, Auto negotiation of speeds and duplex modes on twisted-pair port, and front panel status LEDs. The DMC-300SC will transmit at extended fiber optic distances utilising multimode fiber up to 2 kilometers.Key Features:• Converts 10/100 Mbps Ethernet to 100Base‑FX fiber for long‑distance links • Supports multimode fiber with SC connector up to 2 km transmission • Auto negotiation of speed and duplex modes for simple connectivity • Auto MDI/MDI‑X eliminates crossover cable needs • Status LEDs for power, link/activity, and speed monitoring • Standalone use — no chassis required
