Fast Optical Power Meter Probe Small Size And High Performance
U8721 is a USB interface optical power meter module. It’s sampling
period achieves microsecond, and can collects and processes data at
a high rate of speed.
The U8721 optical power meter module provides a USB communication
port connected with the PC. The operator uses its Demo program to
control the U8721, views the measurement values and sets the
parameters. The U8721 optical power mete module offers superior
performance in testing DWDM Components, AWG&PLC components,
optical amplifiers, and performing other general-purpose fiber
optical test and measurement applications. Compared with other U
Instruments power meter modules, U8721 features high speed sampling
and compact dimension and It is especially suitable for the optical
power meter sampling system which is assembled into various forms
and multiple channels.
Optical power meter probe is a device to measure optical power,
which is usually used in optical fiber communication, Lidar and
other fields. The optical power meter probe can convert the optical
signal into an electrical signal, so as to measure the optical
power.
The common optical power meter probe has two types: crystal type
and fiber type. Crystal type optical power meter probe uses crystal
as the photoelectric conversion material, while fiber type optical
power meter probe uses fiber as the photoelectric conversion
material. Fiber optic power meter probes have higher sensitivity
and wider application range, so they are more common in practical
applications.
