Optical Power Meter Probe High Stability Small Size +5~-80dBm
Based on the photoelectric conversion principle, the optical power
meter probe converts the optical signal into an electrical signal
for measurement. The core component is a photodetector. When the
light signal is illuminated on the photodetector, the photocurrent
is generated, and the power of the optical signal can be calculated
by measuring the size of the photocurrent. In addition, optical
power meter probes often have signal processing circuits for
amplifying, filtering, and digitizing the photocurrent to improve
measurement accuracy and stability.
Optical power meter probes are widely used in optical
communication, optical fiber sensing, optical cable construction,
maintenance and CATV. In optical fiber transmission systems,
optical power meter probes can be used to measure the transmit
power, receive power and fiber link loss of optical signals, so as
to evaluate the performance of optical networks. In addition, in
the field of optical fiber sensing, the optical power meter probe
can also be used to measure the optical power output of the optical
fiber sensor, which provides a basis for the performance analysis
of the sensor.
