Network Media Converter Cudy MC100GSA-20 1x RJ-45 1x SC Single-mode 1310 nm 1000 Mbit/s 20 km

The Cudy MC100GSA-20 is a network media converter that converts between Gigabit Ethernet and single-mode fiber. It supports data transfer rates up to 1000 Mbit/s and a single-mode SC fiber link with a maximum distance of 20,000 m. The unit is compact, housed in metal for improved heat dissipation, and operates from a wide input voltage range (100–240 V) while consuming up to 3 W.

Advantages

Metal housing provides reliable heat dissipation and long service life. High-performance components deliver a mean time between failures greater than 50,000 hours and a 2 Mbit RAM buffer for stable packet handling. Built-in multi-protection features include surge/lightning protection and strong EMI suppression, while LED indicators make link and activity status easy to monitor. The converter supports jumbo frames up to 9 KB and plug-and-play installation with hot-swap capability.

Suitable for

• Extending Ethernet networks over long distances using single-mode fiber (up to 20,000 m)
• Connecting a Gigabit Ethernet device to a fiber backbone
• Indoor and sheltered outdoor network installations requiring durable metal housing
• Environments that need clear visual status via LEDs for link/activity and duplex

Key specifications

• Maximum data transfer rate: 1000 Mbit/s
• Ethernet ports: 1 × RJ-45 (Gigabit Ethernet; 1000/100/10 Mbit/s)
• Fiber ports: 1 × SC single-mode (max distance 20,000 m)
• Buffer memory: 2 Mbit RAM
• Jumbo frame support: up to 9 KB
• 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
• Indicators: FP, TP, Link/ACT, FDX, PWR

How to use

Place the media converter in a ventilated location and connect the SC single-mode fiber cable to the fiber port and the Ethernet device to the RJ-45 port. Apply the supplied DC 5 V power adapter or connect to an appropriate power source within the 100–240 V AC range. Observe the LED indicators: FP/TP show port speed, Link/ACT flashes on traffic, FDX indicates duplex mode, and PWR shows power status. The device is plug-and-play and supports hot swap; no additional software is required.

Recommendations

Install the converter in a dry, ventilated environment and avoid exposing it directly to rain. Use appropriate single-mode SC connectors and quality fiber cabling for long-distance links, and verify fiber transceiver compatibility and cleanliness to ensure optimal signal quality.
