The FHP series of power meters by Grandway Telecom Tech are designed for use with an optical source for performing optical loss measurements on fiber optic cables.

FHP power meters are advanced versions of LPM series meters and are more functional and intelligent. Under laboratory conditions, LANs, WANs and CATV as well as long distance optical networks, the optical power meters, together with Grandway's stabilized laser sources, can be used to identify optical fiber, measure optical attenuation, verify continuity and evaluate fiber link transmission quality.
