Fiber optics are becoming increasingly important as we move toward a more digital world. Fiber optic cables are used to transmit data at high speeds and are found in a variety of settings, from the internet to cable TV. As a fiber technician, you’ll be responsible for installing, maintaining, and repairing these cables.

Before you can start your new job, you’ll need to go through a job interview. This is your chance to show the interviewer that you’re the right person for the job. To help you prepare, we’ve put together a list of common fiber technician interview questions and answers.

Are you familiar with the various types of fiber-optic cables that are used in the telecommunications industry?

The interviewer may ask you a question like this to assess your knowledge of the industry and how it works. This is an opportunity for you to show that you have experience working with fiber-optic cables, as well as demonstrate your ability to learn new things quickly.

Example: “Yes, I am familiar with the various types of fiber-optic cables used in telecommunications. In my last position, I worked on installing all different kinds of fiber-optic cables, including single-mode and multimode cables. Single-mode cables are typically used for long distances, while multimode cables are more commonly used for short distances. I also learned about ribbon cables, which are thin and flexible.”

What are the primary components of a fiber-optic cable?

The interviewer may ask you this question to assess your knowledge of fiber-optic cable and the components that make it work. This is an important skill for a fiber technician because they need to understand how cables function in order to install them properly. In your answer, explain what each component does and give examples of when you’ve used these components before.

Example: “Fiber-optic cables are made up of four primary components—the core, cladding, buffer coating and jacket. The core is the center part of the cable where light travels through. The cladding surrounds the core and reflects any light back into the core. The buffer coating protects the cable from damage while the jacket provides protection against water and other elements.”

How would you test a fiber-optic cable to determine if it’s working properly?

This question is an opportunity to show your knowledge of fiber-optic cable testing. You can answer this question by describing the steps you would take when testing a cable and how you would interpret the results.

Example: “I would first test for continuity, which means I would check that there are no breaks in the cable. If there were no breaks, I would then test for attenuation, or loss of signal strength, by measuring the light intensity at both ends of the cable. If the light intensity was equal at both ends, it would mean there’s no attenuation. However, if one end had more light than the other, it would indicate that there’s some sort of problem with the cable.”

What is the proper procedure for splicing two fiber-optic cables together?

This question is an opportunity to show your interviewer that you know how to splice fiber-optic cables and the proper procedures for doing so. You can answer this question by describing the steps involved in splicing two fiber-optic cables together, including what tools you use and why they are important.
