Optical power meters usually consist of a low-level ammeter or electrometer combined with special features for photonics research or engineering applications. These meters are often designed for use in the laboratory or on the optics bench. It is widely used to perform optical measurements of the power in communication engineering of LAN, CATV and long-distance optical fiber trunk, R&D of optical fiber, optical passive device and optical active device.

Optical power sensor is designed for spectral ripple and low PDL measurements of optical components. It is a right choice for accurate power measurements on fiber optic devices.
