What is a Variable Optical Attenuator?

Variable optical attenuators are commonly used to reduce the absolute light power in a fiber. Typical test applications include linearity testing, receiver sensitivity / range / BER testing, and determining optimum fixed attenuator values for an installed system.

In most cases, An Optical VOA is used in conjunction with an optical power meter. Typically, it is important that the optical attenuator does not degrade the passing signal, has a low sensitivity to wavelength, and low minimum insertion loss.

We offer a high performance handheld instrument with excellent overall specifications, and automation features that are useful in either stand-alone or computer controlled situations, or an inexpensive in-line adjustable attenuator for occasional use.
