MikroTik FTC21-UPS: Fiber Conversion with Built-In Power Resilience
MikroTik FTC21-UPS adds battery backup to fiber conversion with 2.5G SFP, PoE-out, and outdoor design for reliable edge connectivity.
March 31, 2026
The MikroTik FTC21-UPS goes beyond a standard fiber-to-copper converter. It is designed to maintain stable network links even when power conditions are unreliable.
Built for outdoor and edge deployments, this unit combines 2.5G SFP fiber connectivity, Gigabit Ethernet, and integrated battery backup, helping prevent link drops, device reboots, and service interruptions.
Power disruptions are a common cause of downtime at the network edge. The FTC21-UPS includes built-in Li-Ion batteries that help keep links active during brief outages, reducing reboots and link renegotiation.
With fiber uplink, dual Ethernet ports, and PoE-out, it can power connected devices such as radios or cameras while simplifying installation.
Running SwOS Lite, it also provides basic management features like monitoring, VLAN support, and traffic control for added visibility.
The FTC21-UPS adds power resilience to a simple network function. By combining fiber conversion, PoE output, and short-term battery backup, it helps keep edge connections stable and reduces downtime in real-world deployments.
