The Wandel & Goltermann OLP-150 is an optical power meter engineered for fiber optic installation, maintenance, and repair. It delivers precise power and loss measurements across wavelengths from 800 nm to 1700 nm, with display ranges varying by model variant. The instrument supports both modulated and unmodulated light signals, automatic wavelength detection, and dual-wavelength attenuation measurement via TWINtest mode. Field deployment is enabled through battery operation (dry or rechargeable) or AC line adapter power, while rugged construction and interchangeable fiber connectors suit both field and laboratory environments.
