Alloy FCR200SC Media Converter – Reliable 100Mbps Copper to Multimode Fiber Conversion

The Alloy FCR200SC is a dual-purpose Fast Ethernet media converter designed for converting 10/100Base-TX RJ-45 copper Ethernet signals to 100Base-FX multimode fiber via SC connectors, supporting fiber cable distances up to 2 kilometers. Flexible deployment options allow use as a standalone device powered via included external 5V plugpack or USB, or as a hot-swappable module in Alloy's DCR12 Series 12-slot media converter chassis.

Key features include auto-sensing RJ-45 10/100 Mbps ports with Auto-MDIX and full/half duplex support, complemented by a robust 100Base-FX multimode SC fiber port. The device supports Link Fault Pass-Through (LFP) in both Forced Mode (FM) and Far-End-Fault (FEF) configurations, ensuring seamless fault detection and network integrity between fiber and copper links.

Status monitoring is comprehensive with multiple LEDs indicating power, link, activity, and collision status. Configurations such as forced speed and duplex, as well as LFP settings, are easily adjustable via DIP switches on the side panel. The FCR200SC is housed in a compact, rugged all-metal enclosure, built to withstand demanding industrial network environments.

Ideal for legacy Fast Ethernet deployments requiring reliable copper-to-fiber media conversion where multimode fiber connectivity up to 2km is needed, the Alloy FCR200SC is a cost-effective and proven solution for extending network reach while maintaining signal integrity.
