The Agilent/Keysight E5970A is a handheld optical power meter for fiber optic network installation and maintenance. This compact, battery-powered instrument measures optical power across a broad wavelength range and delivers measurement uncertainty of ±5% or ±5 nW. The meter supports relative power measurements with user-adjustable reference values, factory calibration at four standard telecom wavelengths, and compatibility with single-mode and multimode fiber connectors.
