Multi-channel High-precision Optical Power Meter +10 ~ -70dBm
The multi-channel high-precision optical power meter is a key
device used for simultaneously measuring the power of multiple
optical signals in the fields of optical communication, optical
fiber sensing and scientific research. Its core value lies in high
precision, multi-channel parallel measurement, wide dynamic range
and intelligent functions.
Technical characteristics
Multi-channel parallel measurement
It supports synchronous measurement of 4 channels, 8 channels or
even more than 16 channels, and can simultaneously monitor the
power status of multiple optical devices or optical fiber links,
significantly improving the testing efficiency. For instance, in
the production of optical modules for data centers, power
calibration for multiple ports can be accomplished.
High precision and wide dynamic range
Accuracy: Usually reaching ±0.02dB or higher, meeting the
requirements of precision optical systems.
Dynamic range: Up to +10 to -70 dBm/+25 to -55 dBm, covering
measurements from weak signals (such as signals attenuated by
long-distance optical fibers) to high-power signals (such as laser
output).
