Wandel & Goltermann OLA-15 Optical Attenuator

The Wandel & Goltermann OLA-15 is a handheld optical attenuator that delivers precise, continuously variable attenuation from 3 dB to 60 dB across the C and L bands. Designed for field deployment in fiber optic installation, maintenance, and production environments, it enables line loss simulation, receiver sensitivity characterization, and optical power meter calibration with high return loss performance. The instrument features a large LCD display for real-time attenuation readout, individual calibration certification, and bidirectional operation. Battery or AC-powered, the OLA-15 combines portability with measurement accuracy for systems where back-reflection control is critical.
