Product information

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

Key specifications

  • Maximum data transfer rate: 100 Mbit/s (10/100 Mbps)
  • Ethernet ports: 1 × RJ-45
  • Fiber ports: 1 × SC, single-mode, 1310 nm
  • Maximum fiber distance: 20,000 m
  • Power input: 100–240 V AC; DC output 5 V ⎓ 1.0 A
  • Power consumption: ≤3 W
  • Operating temperature: 0 °C to 70 °C; storage: -45 °C to 80 °C
  • Supports jumbo frames up to 9 KB; 2 Mbit RAM buffer; MTBF > 50,000 hours
  • Product colour: Black

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.

Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
20000 m
Maximum data transfer rate: The maximum speed with which data can be transmitted from one device to another.
100 Mbit/s
Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
