Variable Optical Attenuator

A Variable Optical Attenuator (VOA) is used to control optical power by introducing adjustable attenuation into a fiber optic link. Firsol provides variable optical attenuators for fiber optic testing, optical communications, laser systems, power control, receiver protection, and laboratory applications.

Our VOA range includes in-line manual variable optical attenuators, MEMS variable optical attenuators, and adapter type variable optical attenuators. In-line manual VOAs are available for single mode and multimode systems across multiple wavelengths, while MEMS VOAs provide electrically controlled attenuation for automated applications. Adapter type VOAs offer a compact solution for direct connection between fiber interfaces.

Select the appropriate VOA according to operating wavelength, fiber type, attenuation range, insertion loss, optical power, and connector requirements.
