D-Link DMC-300SC – 10/100BASE-TX to 100BASE-FX SC Multi-Mode Media Converter, 2km Fiber Distance, Auto MDI/MDI-X & Full Wire-Speed Forwarding
Overview:
• The D-Link DMC-300SC is a 100BASE-TX to 100BASE-FX Multi-Mode SC Media Converter designed to connect 10BASE-T / 100BASE-TX copper Ethernet to 100BASE-FX fiber media and vice versa.
• It is based on IEEE 802.3 and IEEE 802.3u standards and is designed for use with multi-mode fiber cable using an SC-type connector.
• The converter supports 62.5/125µm multi-mode fiber optic cable with transmission distance up to 2km, making it suitable for extending Fast Ethernet links beyond copper cable limitations.
• It provides RJ45 copper and SC fiber interfaces, with Auto MDI/MDI-X, Auto-Negotiation of speed and duplex mode, and full wire-speed forwarding rate.
• The DMC-300SC can be used as a standalone device without a chassis and includes front panel LED indicators for easy status monitoring.
