MikroTik FTC21-UPS Fiber-to-Copper Media Converter with Integrated UPS, 1x Gigabit Ethernet, 1x SFP, Passive PoE, Battery Backup, Wall Mountable

In remote telecom cabinets and industrial sites, network uptime depends on reliable power and seamless fibre-to-copper conversion. The MikroTik FTC21-UPS combines both in one compact, wall-mountable unit. It bridges a Gigabit Ethernet copper port and an SFP fibre cage while integrating an uninterruptible power supply that keeps your link alive during mains failures using a 12V lead-acid battery. Powered via 12-57V DC jack or passive PoE, it suits solar-powered towers, traffic monitoring, and outdoor wireless backhaul where every watt counts.

Key specifications

• 1x 10/100/1000 Mbps Gigabit Ethernet RJ45 port
• 1x SFP cage for 1.25G fibre modules (module not included)
• Integrated UPS with 12V battery input and built-in charger
• Power options: 12-57V DC jack or passive PoE (12-57V)
• Low power consumption: max 3W (without SFP and battery charging)
• Operating temperature: -40°C to +70°C
• MikroTik RouterOS (simplified) on MIPSBE CPU, 64MB RAM, 16MB flash
• Wall-mountable metal housing with LED indicators for power, Ethernet, fibre, and battery status

Why choose it

The FTC21-UPS eliminates the need for separate media converters and UPS devices, reducing cabling, cost, and failure points. Its wide voltage input and passive PoE support mean you can power it from existing PoE switches or solar charge controllers. The integrated battery charger keeps a 12V backup battery topped up, and on power loss the converter continues operating seamlessly, ensuring your fibre link stays up for critical monitoring or VoIP services.

Ideal use cases

• Remote IP cameras and sensors where fibre meets copper and power is unstable
• Outdoor wireless backhaul links requiring backup power for fibre termination
• Industrial networks needing reliable media conversion with UPS functionality
• Solar-powered installations with 12V battery banks

Good to know

The SFP module is not included; choose any MikroTik-compatible 1.25G SFP for your fibre type. The unit supports passive PoE input on the Ethernet port, but does not provide PoE output. Configuration and monitoring are possible via the simplified RouterOS interface. Always use a 12V sealed lead-acid or LiFePO4 battery with appropriate capacity for your required runtime. The device is designed for indoor use or protected outdoor enclosures.
