## Summary description

Cudy MC100SA-20 is a wired network media converter that connects 100 Mbit/s Ethernet to single-mode fiber (1310 nm) via an SC connector. It provides one RJ-45 Ethernet port and one fiber port, supports jumbo frames and a 9 KB buffer, and reaches up to 20,000 m. Plug-and-play operation, LED indicators, 100–240 V input and 5 V output, typical power 3 W.

## Long description

The Cudy MC100SA-20 Network Media Converter converts between 100 Mbit/s Ethernet and single-mode fiber (1310 nm) to extend network links up to 20,000 m. Housed in a metal case with LED indicators and support for plug-and-play operation, the converter includes one RJ-45 Ethernet port and one SC fiber port and is designed for indoor and outdoor installation with an input voltage range of 100–240 V and typical power consumption ≤3 W.
Advantages
Multi-layer protection provides surge and lightning protection, strong interference suppression and stable, high-speed signal conversion. High-visibility LEDs show fiber and Ethernet status, link/activity, duplex state and power. The metal enclosure improves heat dissipation and durability. The unit supports jumbo frames (9 KB), has a 2 Mbit RAM buffer and a mean time between failures greater than 50,000 hours.
Suitable for
Extending Ethernet networks over long distances via single-mode fiber (up to 20 km)
Connecting remote network segments or CCTV systems where fiber is required
Small office or industrial edge installations requiring compact media conversion

How to use
Install the converter in a dry, ventilated location. Connect the single-mode SC fiber cable (1310 nm) to the fiber port and the Ethernet cable to the RJ-45 port. Apply mains power using the supported 100–240 V supply and the included DC 5 V adapter if provided. Monitor the LEDs: FP indicates fiber speed, TP indicates Ethernet speed, Link/ACT flashes on activity, FDX shows duplex mode and PWR shows power presence. The device is plug-and-play and requires no additional software; hot-swap of links is supported.
Usage recommendations
Place the converter where airflow is not obstructed, avoid direct exposure to water, and use proper fiber connectors and cable management. Verify link speed via LEDs and ensure compatible fiber transceivers at both ends for reliable long-distance links.
