Optical
electric meter
People are usually
conversant in electronic multimeters which may measure voltage, current, and
resistance. An optical electric meter and OTDR looks and works
a bit like a multimeter. It consists of a display unit and a calibrated sensor
to live the sunshine power transmitted in optical fibers.
Its place of use
Optical power meters
are broadly utilized in the fiber optic communication industry. it always comes
in two types: desktop type and handheld type.
The desktop type has
much higher resolution and is typically utilized in R&D applications within
the lab, fiber optic components, and systems manufacturing floors.
Power meter’s
working wavelength
In the handheld
optical power market, the foremost popular wavelengths are 850nm, 1300nm,
1310nm, and 1550nm. 850nm and 1300nm are for multimode applications. 1310nm and
1550nm are for single-mode applications.
It is best to settle
on an optical electric meter which is calibrated for all four wavelengths to
urge the foremost out of your money. So you'll cover both multimode and
single-mode network applications of the optical power meter.
Fiber optic
electric meter Traceable calibration
Power meters are
calibrated employing a traceable calibration standard like a NIST standard.
Standards and measurements for the U.S. industry are offered by NIST
laboratories.
Detector types
The optical detector
during a handheld optical electric meter is liable for converting light energy
into electronic volt therefore the circuit card within the instrument can
measure it accordingly. The sort of detector determines the wavelength range
and its dynamic range.
Silicon type detectors
can sense 350nm to 1100nm wavelength light. Germanium detectors can sense 750nm
to 1800nm. The foremost popular detectors can measure 850nm to 1650 nm.
Dynamic range
An optical power
meter's dynamic range spec tells you what light power range it can effectively
and properly measure. The optical light source is very
reliable.
Optical power
meters Manufactures
The handheld electric meter market is crowded with Agilent, Anritsu, EXFO, Noyes, and a few other
less-known brand names. But this sort of product is pretty mature and typically
you'll safely go searching.
