4-Channel PC-Controlled LC Adapter Optical Power Meter With
Built-In Probe
The four-channel optical power meter is mainly composed of
photodetector, amplifier, filter, analog-to-digital converter and
microprocessor. In the measurement process, the optical signal is
received by the photodetector and converted into an electrical
signal, which is processed by the amplifier and filter, and then
converted into a digital signal by the analog-to-digital converter,
and finally processed and displayed by the microprocessor. This
process ensures measurement accuracy and stability.
Characteristics and advantages
High sensitivity: The four-channel optical power meter has
extremely high sensitivity and is able to detect very weak initial
signal levels for real-time tracking and increased signal levels.
High accuracy: With optimized high-performance analog electronics
and noise suppression technology, four-channel optical power meters
provide ultra-low and stable zero signal levels and peak accuracy
over the entire power range.
Multi-channel measurement: The four-channel optical power meter can
simultaneously measure the optical signal of four channels, which
greatly improves the measurement efficiency.
Large dynamic range: has a deep dynamic range, can adapt to
different intensity of light signal measurement needs.

Application field
Optical communication: The four-channel optical power meter is used
in the field of optical communication to measure the signal
strength of each node in optical fiber communication and help
regulate the transmission and reception of optical signals. At the
same time, it can also be used to test optical fiber connectors,
optical fiber attenuation, etc.
Optical fiber sensing: In the field of optical fiber sensing, a
four-channel optical power meter can be used to measure the bending
degree and bending direction of the optical fiber, so as to reflect
the temperature change of the measured object. In addition, it also
has a wide range of applications in pressure sensors and strain
sensors.
Life Sciences: In the field of life sciences, four-channel optical
power meters can be used for cell and molecular measurements. For
example, in protein measurement, a four-channel optical power meter
can be used to measure the absorption value of the sample, thereby
calculating the concentration of protein in the sample.
