Other users also ask the following questions:
1.How accurate are optical power meters?
The most accurate field optical power meters claim 1% calibration
accuracy. This is orders of magnitude less accurate than a comparable
electrical meter.
2.What is the range of optical meter?
Generally, the optical power that optical power meter can measure
is ranging from -70dBm to +30dBm. Interface Type: A length of fiber patch cable is usually used to
connect the port on optical power meter with the corresponding port
of devices for fiber optic testing.
