The FID-30R includes an
optical power meter and succeeds the FID-25R while the FID-31R, the
updated standard model, replaces the FID-26R. The fibre
identifiers, used for identifying the light power presence in
optical fibres, include three detecting functions: TONE, TRAFFIC,
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. The fibre identifiers can
detect the presence of several kinds of light signal and indicate
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.
Other features of the battery
operated FID30R/FID31R include robust body design, easy-to-use
fibre clamp, status indicator and adjustable settings for result
retaining, buzzer volume, backlight brightness, auto dimming and
auto power off.
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
