Fiber Type Identification refers to the process of determining the specific types of optical fibers present within deployed hybrid-span fiber cables using Brillouin Optical Time Domain Analysis (BOTDA). This identification is crucial for various aspects of network management and optimization, such as planning, setting appropriate launch powers, and selecting suitable modulation formats.


Inline Fiber Type Identification using In-Service Brillouin Optical Time Domain Analysis

We proposed the use of BOTDA as a monitoring tool to identify fiber types present in deployed hybrid-span fiber cables, to assist in network planning, setting optimal launch powers, and selecting correct modulation formats.
