Variable in-line optical attenuators,also know as adjustable in-line optical attenuator or short as VOA, are used to permit dynamic control of optical power levels in a fiber. It can be applied to adjust power level of signal in the optical communication at the output of light sources, E/O converters and for the linear or dynamic range of power meter. Furthermore, they can the used in optical amplifier systems to balance the gain across the different operating wavelengths.
Variable In-line Fiber Optical Attenuator VOA ST SM UPC APC 0-60dB
SZOPT offers a complete line of variable in-line optical attenuators.These variable optical attenuators allow the user to manually vary the attenuation of the signal in the fiber as it is transmitted through the device. These variable attenuators can be used to precisely balance the signal strength in a fiber optic circuit or to balance the optical signal when evaluating the dynamic range of the measurement system.Please reach us for details.
