Perform a visual inspection of the optical fiber cable line to look for any visible signs of damage or abnormalities. Effective maintenance of cable intermediate joints requires a structured approach combining visual inspection, electrical testing, and preventive care protocols. The inspection process involves multiple stages, from initial visual assessment to advanced diagnostic testing, each designed to identify. This document outlines the Panduit recommended procedures for visual inspection and cleaning of multimode and singlemode structured cabling system interconnect components (connectors and adapters) and specifies workmanship requirements, tools and best practices, to be utilized for end face. For every fiber optic cable plant, you need to test for continuity and polarity, end-to-end insertion loss and then troubleshoot any problems.
