EXFO FOT-90 FIBER OPTIC TEST SET REPAIRED The FOT-90 units are highly sophisticated fiber optic power/attenuation meters in a rugged hand-held format designed for both field and laboratory applications. NBS traceable calibration parameters are permanently stored in the instrument memory for ease of use. The instrument has been designed to be easy to use without any particular training.
The FOT-90 constitute a highly accurate fiber optic power meter. The FOT-90 is available with an optional built in LED/Laser light source (G) which are energized from a seperate battety circuit to avoid power failure with your power meter.
High sensitivity:
-80dBm @ 850 nm with FOT-91
-73dBm @ 1300 nm with FOT-92
-76dBm @ 1300 nm with FOT-93
Excellent resolution (0.01 dBm/dBr)
Readings in units of dBm, dBr, and Watt
Push button selection of (20) calibrated wavelengths
Constant memory of last operatvive wavelength. The instrument will operate at the same calibrated wavelength it did before it was turned off
NiCad rechargeable batteries with low battery detection and full recharge protection for long life
The powermeter will operate for more than (8) hours on a full charge. If you are also using the built-in LED laser option then your instrument will operate approximately 2 to 2.5 hours. A full battery charge requires 16 hours of charging and will automatically stop after that period if the AC/DC converter is left connected.
