D-Link DMC-700SC

The D-Link DMC-700SC is a standalone Gigabit Ethernet media converter that bridges 1000BASE-T copper networks with 1000BASE-SX multi-mode fiber optic installations. It converts twisted-pair signals to fiber signals across distances up to 550 meters (1804.46 ft) using 62.5/125μm multi-mode cable, eliminating the need for external chassis or dedicated infrastructure.

## Technical Specifications

The DMC-700SC implements IEEE 802.3ab (1000BASE-T) and IEEE 802.3z (1000BASE-SX) standards, delivering full wire-speed forwarding in full duplex mode. The single RJ-45 copper port supports 4-pair Cat. 5 STP cable (EIA/TIA-568) up to 100 meters with auto MDI/MDI-X capability. The SC fiber connector accommodates multi-mode optic cable with a maximum reach of 550 meters on the fiber side.

Power requirements are minimal: 7.5 V DC at 1.5 A via external AC adapter, consuming 5.5 W maximum. Operating temperature range spans 0°C to 40°C with non-condensing humidity tolerance of 10% to 90%.

## Key Features

• Plug-and-play operation — no configuration required for basic deployment
• Auto-negotiation on TX port for duplex mode selection
• Configurable fiber mode switch (DIP Switch 1) for forced or auto-negotiation operation
• Link Loss Return (LLR) enable/disable via DIP Switch 2 for remote/monitor endpoint differentiation
• Dual LED indicators: Power (PWR) and Link/Activity (LINK/ACT) for operational monitoring
• Compact form factor: 88.9 mm × 120.7 mm × 25.4 mm; 0.3 kg weight

## Typical Applications

Industrial and commercial network extension scenarios requiring Gigabit connectivity across multi-mode fiber backbones. Ideal for bridging legacy copper infrastructure with fiber-based campus or warehouse networks where distance constraints exceed copper-only limitations.

## Compatibility & Integration

Meets FCC Class A/B and VCCI Class A regulatory requirements. CE certified for Class A operation. Operates across industrial and commercial temperature ranges with storage capability from -25°C to 70°C.
