The Anritsu CMA5 Optical Loss Test Set is a pocket-sized instrument that combines a laser diode light source and InGaAs power meter in a single unit for field measurement of optical power and loss in fiber optic networks. It delivers fast, accurate loss characterization across single-mode and multimode fiber installations without warm-up time. The device integrates dual functionality—light source and power meter—into a rugged 300 g platform, eliminating the need for separate instruments during cable installation, commissioning, and maintenance operations.
