  • Page 37: Chapter 1: Cma50 Series Overview

    Chapter 1: CMA50 Series Overview The CMA50 series consists of Power Meters, Light Sources and Loss Test Sets, all of which are light-weight, yet rugged in design to handle any testing situation. Designed for attenuation and throughput measurements of fiber optic links, the CMA50 Power Meters are ideal for troubleshooting networks.

  • Page 38: Theory Of Operation

    Theory of Operation The interchangeable connector adapter system couples light from the fiber under test to the CMA50’s receiver, a high performance InGaAs photodetector that converts the light energy to an electrical signal. The CMA50 then digitizes the signal for processing by a microcontroller.
