Multimode Variable Fiber Attenuator 50u KI7020B

The KI 7020B hand held Fiber Optic Variable Attenuator is a precision handheld instrument commonly used for testing 50u multimode mode fiber systems for optical system margin and linearity. Superior specifications, high productivity and remote control capability also make this a genuine laboratory grade instrument. An additional typical application is as a passive adjustable attenuator pad in a transmission system.
