Fiber-Optic Maintenance I: Outside Plant

Course Overview

The NCTI® Fiber-Optic Maintenance I: Outside Plant course introduces the knowledge and hands-on skills necessary to support the reliability and performance of fiber-optic networks in the field. This course explores industry standards, proper documentation practices, and the structured approach to maintenance planning. Students will investigate common trouble spots across equipment rooms, aerial and underground segments, and examine how fiber damage, often hidden, can impact network integrity. Through practical learning, the course covers connector cleaning, inspection techniques, and using specialized test equipment like optical time division reflectometers (OTDR), visual fault locators (VFL), and power meters. It emphasizes understanding the layout and challenges of passive optical networks (PON) and diagnosing and restoring faults in the optical distribution network. Whether preparing for a career in installation, maintenance, or network support, this course lays the groundwork for effective troubleshooting and system upkeep in today’s high-demand fiber-optic environments.
The estimated completion time for this course is 8 hours. The maximum allotted time is four months from enrollment.
