The Viavi 228022 is a SmartClass OLA-55M Single-Mode Variable Attenuator with Level Control Mode and APC. This future-proof variable attenuator is designed for fiber system testing - as well as installation, maintenance, and production of single-mode fibers. It also provides an implemented power meter for stabilized level controller applications.

• Reduces testing time: Quick start operation and no warm-up
• Excellent overall accuracy: 400 adjustable wavelengths

The Viavi 2280/22 SmartClass OLA-55M Single-Mode, Variable Attenuator with Level Control Mode, APC, is a future-proof, improved variable attenuator designed for fiber system testing as well as installation, maintenance, and production of singlemode fibers. The OLA-55M Motorized Optical Level Attenuator also provides an implemented power meter for stabilized level controller applications.

The SmartClass OLA-55M Optical Level Attenuator can be used as part of a SmartClass Optical Test Kit (sold separately) that contains all of the tools, including instruments and accessories, necessary to perform professional-grade power or loss tests in the field.

Automatic Level Controller Mode

Most applications require a defined power level rather than a certain level of attenuation. A standard attenuator only allows the setting of an attenuation value. Against it, the level controller mode of the SmartClass OLA-55M allows direct setting of a precise and defined optical power level. It integrates the function of an attenuator and a power meter and therefore avoids extra steps to adjust the power level with a separate power meter. Being in this mode the attenuator is automatically counterbalancing the changes of varying input power level and provides a stable output level.
