Multimode Variable Fiber Attenuator | Kingfisher International

Multimode Variable Fiber Attenuator 50u KI2020

50u core MM variable optical attenuator
Best optical specifications
Easy to use, rugged & reliable

Overview

This 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.

Easy to use, accurate & productive instrument
Excellent linearity and absolute loss accuracy
Power handling to >+30 dBm / 1000 milliwatts
Broadband, flat λ response
Low minimum insertion loss
Excellent ORL & PMD characteristics
Supplied with SC, ST, LC interchangeable connectors
Remote control (LabWindows) software
Set attenuation is unaffected by power on/off status
Very long battery life
