Product Features
Technical Overview
This media converter provides a dedicated conversion path between one RJ-45 port for twisted-pair copper and one SC duplex port for multi-mode fiber, supporting full-duplex operation. It handles Fast Ethernet (100 Mbps) traffic, backward compatible with 10 Mbps Ethernet, ensuring seamless integration into legacy or mixed-speed networks. The optical interface uses 1310 nm wavelength, matching standard multi-mode transceivers for consistent signal quality.
Distance support extends to 2 kilometers over fiber, significantly beyond copper's typical 100-meter limit, while maintaining 100 Mbps throughput. The converter accepts 50/125 µm and 62.5/125 µm fiber core/cladding specifications, covering most multi-mode cable types. Power is supplied via an included AC adapter with a barrel connector, delivering stable 5-VDC input for reliable operation in varied electrical environments.

Deployment / Use Cases
This media converter is engineered for scenarios where network segments must traverse longer distances or harsh environments. Common applications include extending LAN connections between buildings in a campus, linking industrial control systems across factory floors with high EMI, or integrating fiber backbones into existing copper-based office networks. Its 2 km range makes it suitable for outdoor or cross-campus links where direct copper runs are impractical.
In retail or warehouse settings, the converter can connect remote POS terminals or surveillance cameras over fiber to central switches, ensuring reliable video and data transmission. For IT closets or data centers, the rack-mountable option allows tidy integration into patch panels or network racks, conserving space while providing essential media conversion. The unit's compatibility with standard multi-mode fiber simplifies upgrades or expansions without replacing entire cabling infrastructures.
