The FiberFox SFI-10B is a smart, intelligent optical fiber identifier designed to modernise field maintenance. By integrating NFC and Bluetooth (BLE) technology, it connects directly to a smartphone app, enabling a "Digital Marking Sheet" workflow. This allows technicians to upload real-time status updates and record line information immediately to NFC tags on closures, replacing traditional paper records.

Engineered for safety and efficiency, the SFI-10B allows for true one-hand operation. It eliminates the need to manually hold the fiber during testing, significantly reducing the risk of accidental disconnection. The digital integration prevents human errors associated with handwriting (loss, damage, or humidity) and enhances security through NFC tag encryption and app login requirements.

Weighing only 120g (160g with batteries), the SFI-10B is highly portable while delivering professional performance. It features a low insertion loss of < 0.5 dB (at 1310nm), a wide detection range of 800–1700nm, and supports various signal tones. Powered by standard AA batteries, it provides over 5,000 readings, making it a reliable tool for extensive field use.
