EXFO FOT-22AX Data Sheet

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.

Key Features

" Direct loss measurement in dB
" Five electronically calibrated wavelengths
" Shockproof holster also acts as storage compartment for fiber-

optic adapters and replacement battery

" Auto-off function
" FOT-10A: power measurements in dBm
" FOT-20A: power measurements in dB, dBm and W

Ruggedness

The FOT-10A and FOT-20A Power Meters meet Telcordia's strict drop-test requirements. A holster is included for added durability and
portability of connector and battery accessories. A complete range of EXFO fiber-optic adapters is available for connector interface. A single
9 V battery powers these units for over 14 hours.

Custom Calibration

Like all EXFO power meters, the FOT-10A and FOT-20A can be calibrated at a custom wavelength.

Applications

" Transmitter power measurements (dBm and W)
" Fiber-link loss testing (dB)
" Component insertion-loss testing (dB)
" Fiber identification with 2 kHz signals
" LAN installation and maintenance applications

Accessories

" Battery
" AC adapter/charger
" Rigid carrying case
" Shockproof holster
