The FPM-250
Simply the BEST ShirtPocket Fiber Power
Meter you can buy!

• +5 to-75 dBm dynamic range

Dimensions: 5″ L x 2.5″ H x 1″ D, 130 mm L x 64 mm H x 25 mm D

(+25 to -55 dBm for the CATV model)

• Four digit display for .01 db resolution
• Large area InGaAs detector for the
ultimate performance at 1550 nm

• Universal 2.5 mm ferrule adaptor
(1.25 mm ferrule adaptor optional)

• Two hundred hour battery life
• Storage of three reference values for
dB relative measurements

• Auto-off mode for maximum battery life
• Virtually indestructible hard
carrying/storage case included

The FPM-250 is the result of years of
refinement of light measurement technology. This small and rugged unit is
comparable with fiber optic power meters
many times it size and price.
The FPM-250 incorporates a large-area
Indium Gallium Arsenide detector which
provides much improved temperature
stability at 1550 nm than the Germanium
detectors used in convention instruments. This detector has much higher
resistance than Germanium which enables the unit to deliver 15 to 20 dB
greater sensitivity at the low end and, as
a result, better linearity at intermediate
power levels.

The FPM-250 is equipped with a simple universal 2.5 mm ferrule adaptor that accepts FC, ST,
SC, DIN and similar connectors without the need
for a multitude of costly and easy-to-lose screwon adaptor caps.
For higher power optical measurements such as
those frequently required in the CATV industry,
the FPM-250 with HP (high power) option permits measurements of up to 25 dBm.
Each unit has three calibration wavelengths of
850, 1310, and 1550 nm. A reference level for
each wavelength can be stored in non-volatile
memory for the purpose of making loss measurements.
A battery saving Auto-Shutdown mode may be
invoked whereby the unit will power itself down
after 20 minutes without a key activation. Even
without this feature, the 200 hour battery life far
exceeds that of most competitive units.
The rugged carrying case provided with each unit
protects the unit from virtually any abuse for years
of use. (see photo on reverse)
The FPM-250 is by far the best value in fiber
optic instrumentation today and is simply the best
fiber power meter in its class. Contact us for a
