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.

Common Fiber Technician Interview Questions

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.

Example: “The first step when splicing two fiber-optic cables together is to clean both ends of each cable with a cleaning solution. This removes any dirt or debris from the end of the cable, which helps prevent it from interfering with the splicing process. Next, I align the two cables so that the connectors face each other. Then, I apply heat to the connector on one end of the cable until it softens. Once it’s softened, I insert it into the connector on the other cable.”

Provide an example of a time when you had to troubleshoot a problem with a fiber-optic cable system.

This question can help the interviewer gain insight into your problem-solving skills and ability to work independently. Use examples from previous experience where you had to troubleshoot a system on your own or with another technician.

Example: “In my last position, I was working with a team of technicians who were installing fiber optic cables in an office building. We encountered some issues when we tried to connect the cables to the router. After testing the cables, I realized that one of them wasn’t functioning properly. I replaced it with a new cable and reconnected it to the router. The connection worked, and we were able to finish our installation.”

If a customer complained about slow internet speeds, how would you troubleshoot the issue?

This question can help the interviewer assess your customer service skills and ability to troubleshoot problems. Use examples from previous experience in which you helped customers solve internet speed issues or other technical problems.

Example: “I would first ask them what their internet speeds were supposed to be, then I’d test my own internet connection to see if it was slow as well. If both of our connections are working properly, I would check for any possible interference between the modem and router. If there’s no interference, I would reset the modem and router to ensure they’re functioning properly. If that doesn’t work, I would replace the router with a new one.”

What would you do if you noticed a damaged section of a fiber-optic cable while performing maintenance?

This question can help interviewers assess your problem-solving skills and ability to work independently. In your answer, try to demonstrate that you would carefully consider all possible solutions before making a decision.

Example: “If I noticed a damaged section of the cable while performing maintenance, I would first check if it was repairable or if it needed to be replaced. If it could be repaired, I would use my tools to fix it. However, if it couldn’t be fixed, I would replace the entire cable. Fiber cables are expensive, so I would make sure to take extra care when removing the old one to ensure I don’t damage the new one.”

How well do you pay attention to detail when performing repetitive tasks?

Attention to detail is an important skill for fiber technicians because they often perform the same tasks over and over. Employers ask this question to make sure you have the ability to pay attention to small details when performing repetitive tasks. In your answer, explain that you are able to pay close attention to detail while performing these types of tasks. Explain how you use your attention to detail to ensure you complete all of your work accurately.

Example: “I am very good at paying attention to detail. I find that working in a field where you perform similar tasks every day helps me develop my attention to detail skills. When I was working as a cable technician, I would do the same task multiple times per day. For example, I would connect a coaxial cable to a television or modem many times each day. By doing this so frequently, I developed the ability to pay close attention to detail when connecting cables.”

Do you have experience working with a splicing machine?

Splicing machines are a common tool used by fiber technicians. Employers ask this question to make sure you have experience using one and can do so safely. If you don’t have any experience with splicing machines, consider asking your potential employer about the specific type of machine they use. You can also research how to operate it online.

Example: “I’ve worked with several different types of splicing machines in my previous roles. I find that I am most comfortable working with fusion splicers because I like being able to see what I’m doing while I work. However, I know there are many benefits to other types of splicers, such as the ability to splice without removing fibers from their protective tubes.”

When installing a new fiber-optic cable system, do you prefer to work alone or with a partner?

This question can help the interviewer determine how you work with others and your communication skills. Your answer should show that you are a team player who is willing to collaborate with others when necessary.
