Multimode Variable Fiber Attenuator | Kingfisher International

Overview

This hand held fiber optic variable attenuator is a precision handheld instrument commonly used for testing 62.5 u multimode mode fiber sytems for optical system margin and linearity. Superior specifications, high productivity and remote control capability also make this a genuine laboratory grade instrument. An additonal typical application is as a passive adjustable attenuator pad in a transmision system.
