Media converter D-Link DMC-G10SC/E 100/1000BaseT to 1000BaseLX SC fiber

The D-Link DMC-G10SC/E media converter converts copper Ethernet (100/1000Base-T) to single‑mode fiber (1000Base‑LX) using an SC connector. Designed to integrate fiber links into existing copper networks, it supports gigabit throughput for long-distance backbone or campus connections and enables simple extension and segmentation of network topology. The compact converter provides a straightforward way to combine copper-based devices and fiber infrastructure while maintaining link performance and reducing electromagnetic interference over long spans.

Advantages

The unit supports both 100Base-TX and 1000Base-T on the copper port and provides a 1000Base-LX fiber interface, allowing seamless speed conversion and network compatibility. Its SC connector and single‑mode fiber support extend link distances compared with copper cabling, while the compact form factor and low power usage make it suitable for installation in wiring closets or at remote network endpoints. The converter operates transparently at Layer 1, preserving existing network protocols and addressing schemes without requiring configuration changes.

Suitable for

• Extending LAN links over long distances between buildings or across a campus
• Connecting copper-based switches, servers or DVRs to single‑mode fiber backbones
• Segmenting networks to reduce electrical interference and ground loop issues
• Upgrading parts of a network to gigabit fiber without replacing existing copper endpoints

Key specifications

• Copper port: 10/100/1000Base‑T autosensing RJ‑45
• Fiber port: 1000Base‑LX single‑mode with SC connector
• Supported wavelengths and reach suitable for single‑mode LX optics (long‑reach links)
• Layer 1 media conversion with transparent forwarding
• Compact, external power supply form factor and low power consumption

How to use

Install the media converter near the copper endpoint or in a network closet and connect the RJ‑45 copper cable from the device or switch to the converter’s copper port. Terminate single‑mode fiber to the SC connector on the converter and ensure appropriate fiber polarity and continuity. Power the unit using the provided external power adapter and verify link LEDs on both ports for established connectivity. No configuration is required for standard media conversion; the device will negotiate link speed and duplex on the copper side while providing a fixed gigabit fiber interface.

Recommendations

Use quality single‑mode fiber and properly rated LC/SC patch cords with correct endface cleaning. Match fiber type and transceiver reach requirements on both ends of the link and maintain appropriate fiber bend radius and routing practices. For installations spanning campus backbones, verify link budget and consider fiber splicing or patch panel termination for long, multi‑segment runs.
