The Wandel & Goltermann OLA-15 is a rugged, compact, and lightweight hand-held variable optical attenuator designed for single-mode fibre optic applications. It enables engineers to simulate line loss for BER (Bit Error Ratio) testing, determine system margin and receiver sensitivity, and calibrate optical power meters. The instrument offers continuous attenuation adjustment over its full range with a 4-digit LCD displaying absolute attenuation values including connector loss. Interchangeable connector adapters (BN 2060/00.xx series) allow compatibility with DIN, FC, SC, and ST connector types.
