D-Link 100Base-TX to 100Base-FX Single-mode Fiber (SC) Media Converter (DMC-540SSC)

The D-Link DMC-540SSC Media Converter enables seamless integration of copper Ethernet networks with long-distance single-mode fiber connections. Designed for network expansion, it converts 10/100 Mbps copper signals from Cat 5/5e UTP cables to 100 Mbps fiber optic connections, supporting distances of up to 40 km with a 1310 nm wavelength. This converter is ideal for linking offices, campuses, and remote network segments where Ethernet cabling alone is insufficient. With store-and-forward transmission, full wire-speed forwarding, and auto-MDI/MDIX support, the DMC-540SSC delivers reliable, high-performance connectivity with easy installation and diagnostic monitoring via LED indicators.

Product Features

Copper-to-Fiber Conversion

Converts 10/100 Mbps copper Ethernet signals to single-mode fiber, extending network reach up to 40 km.

Long-Distance High-Speed Connectivity

Supports Fast Ethernet (100 Mbps/200 Mbps) and standard Ethernet (10 Mbps/20 Mbps) with full-duplex operation for efficient data transmission.

Media Flexibility

Compatible with Cat 3/4/5/5e UTP cables for short-distance copper connections and single-mode fiber with SC connectors for long-distance links.

Auto-MDI/MDIX Support

Simplifies installation by automatically configuring crossover or straight-through connections without additional cables.

Store-and-Forward Transmission

Ensures accurate data delivery by checking each packet before forwarding, reducing network errors.

Diagnostic LEDs

Power, speed, full-duplex/collision, and LINK/ACT indicators provide easy monitoring and troubleshooting of network status.

Compact Design

Small form factor with a 5 V/1 A external power adapter for convenient deployment in tight spaces.

Environmental Tolerance

Operates in temperatures from 0°C to 50°C and humidity of 5% to 90% non-condensing, with storage ranges from -20°C to 70°C.
