SmartClass OLA-54/-55/-55M
Optical Level Attenuators
Optical Level Attenuators
The SmartClass OLA-54/-55/-55M Optical Level Attenuators are future-proof, improved variable attenuators for fiber system testing as well as installation, maintenance, and production of multimode fibers  and singlemode fibers. The OLA-55M Motorized Optical Level Attenuator provides in addition an implemented power meter for stabilized level controller applications.
The SmartClass OLA-54 and OLA-55 Optical Level Attenuators can be part of a SmartClass Optical Test Kits that contain all of the tools, including instruments and accessories, necessary to perform professional-grade power or loss tests in the field.
Key Features
