The Agilent 81633A is an optical power sensor module engineered for precision measurements across the near-infrared spectrum. It integrates with Agilent’s 8163A and 8164A Lightwave Multimeters and compatible mainframe systems to deliver accurate, repeatable power data in telecommunications, photonics research, and production test environments. The module uses an InGaAs detector element and operates across both single-mode and multimode fiber systems.
