A weatherproof Fiber-to-Copper converter with 2.5G SFP and 2x Gigabit Ethernet ports, including PoE-out on Ether2. Its integrated battery keeps links stable during short power interruptions, preventing unnecessary renegotiations and device reboots.
At the network edge, it is rarely the fiber that fails. It is unstable power, brownouts, short outages, and voltage drops that trigger renegotiations, device reboots, and unnecessary support tickets. The FTC21-ups is built to save you some major headaches when dealing with unreliable power sources

The FTC21 is not just a simple media converter. It runs a full version of SwOS Lite, offering advanced management features:
Interface monitoring and management
VLAN support
SNMP reporting
Basic traffic shaping
Advanced packet filtering with Access Control Lists - allowing for packet filtering, accounting, and VLAN tagging based on Layer 2, 3, and 4 protocol header conditions.
What makes the FTC21-ups different is what happens when power becomes unstable. Inside, there is a pair of Li-Ion NCA 18650 batteries. Not for running your network all night, but for surviving short outages, brownouts, and those moments when everything almost crashes.
It keeps the link up when the power is flickering, preventing unnecessary device renegotiation.
The battery is intelligently managed:
Inactive during shipping;
Activated on first power-up;
Can be put into ship mode remotely via SwOS when necessary.
Estimated from measured battery behavior. Actual runtime depends on load and temperature.
