Fiber Characterization Technician (FCTT)

This course teaches workers how to effectively communicate and explain issues found while testing optical network infrastructure, including PMD, CD, and attenuation profiling. They will also learn how to demonstrate the results obtained during testing.

A Fiber Characterization Technician training course prepares participants to test, analyze, and document the performance of fiber optic networks, ensuring they meet the requirements for high-speed data transmission in modern communication systems, such as 4G/5G, data centers, and enterprise networks. This training is essential for technicians involved in deploying, maintaining, and troubleshooting fiber optic systems to ensure they can handle the increasing demands of bandwidth and low-latency communication.
