Fiber Identifiers


FID-30R / FID-31R – Optical Fibre Identifiers


Fujikura now offers Advanced Optical Fibre Identifiers, the FID-30R and FID-31R, which feature the world’s highest TONE signal-detection sensitivity. Used for identifying light presence in optical fibres, they include three detecting functions: TONE, TRAFFIC, and ONU. The FID-30R has an optical power meter built in over the standard FID-31R model. Both models include a trigger operated clamp to macro-bend the fibre in order to leak light which is then detected by two photo sensors. They can detect the presence of several kinds of light signal and indicate signal directions.

Our user friendly fibre identifiers provide ONU signal detection and are fully equipped with an LCD colour touch panel, USB, constant clamp force and trigger-locking mechanism, making them even more unique when compared with similar products on the market.The trigger lock function ensures the fibre is clamped with constant pressure, while the 2.4” colour LCD touch panel, equipped with a backlight function, allows the user to view the estimated optical power in the fibre and select the desired wavelength of 1310nm, 1490nm, or 1550nm. Identification of modulated tones at 270Hz, 1kHz and 2kHz is provided, along with continuous wave and ONU signals. Users are also able to select from three detection sensitivity modes; normal, fast and fine.

The fibre identifiers can be used for UV-coated fibre, 0.9mm diameter tight buffered fibre, fibre cord up to 3mm in diameter, and fibre ribbon with up to 12 fibres.
