FVA-60B

1 Introducing the FVA-60B

Variable Optical

Attenuator

The FVA-60B is a variable optical attenuator used for bit error rate and system
testing, optical margin analysis, calibration verification and component testing. It
can be configured for singlemode or multimode fibers; calibrated wavelengths are
either 1310/1550 nm or 850/1300 nm respectively.
The FVA-60B is powered by the built-in rechargeable Ni-MH battery pack, the 9 V
alkaline battery, or the AC adapter/charger.
