Designed to withstand the rigors of field testing
Five calibrated wavelengths
Auto-off function
Compatible with singlemode and multimode fibers
Handheld Power Meters
FOT-10A and FOT-20A

The FOT-10A and FOT-20A Power Meters are compact, accurate,
rugged and easy-to-use instruments for both power and loss
testing. Like all of EXFO's handheld power meters, the FOT-10A
and FOT-20A can be calibrated to a custom wavelength, free of
charge.
Versatility in the Field
Performance
The FOT-10A and FOT-20A incorporate EXFO's linear amplification
technology and are traceable to NIST. They offer five calibrated
wavelengths, and perform 2 kHz signal detection for fiber
identification. Unit configurations are available with germanium or
high-power germanium detectors. An electrical offset nulling
feature makes the FOT-10A and FOT-20A ideal for operation in
extreme temperature conditions.
