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, A 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.
