  • How to measure the optical attenuation of the main trunk of the optical distribution box

    How to measure the optical attenuation of the main trunk of the optical distribution box

    The primary tool for measuring attenuation in installed fiber is an Optical Time Domain Reflectometer, or OTDR. When the light crosses materials with different refractive indices the light beam will be partially refracted at the boundary surface, and partially reflected. It's measured in decibels per kilometer (dB/km), and it determines how far a signal can travel before it becomes too weak to read. The conventional method, known as the cutback method, involves coupling fiber to the source and measuring the power out. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. The overall fiber attenuation is of greatest interest to the system designer, but the.
