Common Issues about Fiber Optic Cable

Fiber optic has the strength to transmit signals much faster than copper cable. In addition, it covers larger distances than any other internet connection type. While it has the potential to boost the performance of a wide range of equipment, fiber optic cable is susceptible to various issues that can affect its functioning. This article will help you diagnose issues related to fiber-optic cables and ways to resolve them.

Many Fiber Internet users don’t realize that fiber optic can be just as prone to damage as any other wire for an internet connection. Despite proper installation and regular maintenance, it may experience damage over time.

Understanding and Fixing Fiber Optic Cable Issues

Fiber optics may damage in many ways. For example, fibers are likely to break when they undergo a lot of stress or if bent excessively. Similarly, they may contain faulty, contaminated, or too many connectors, which can result in signal loss. On the other hand, if the quality of splices deteriorates due to scratches, dust, or humidity, it can damage the cable.

If you are planning to check fiber optic cables on your own, you will need the following equipment:

Fiber Optic Light Source

A fiber optic light source lets you check if the wavelength output meets its standard requirements. It is combined with a fiber optic power meter to detect issues within the fiber.

Fiber Optic Power Meter

A power meter is used to identify the test precision, changes in appearance, and the range of power measurement of the fiber optic cable.

Fiber Optic Multimeter

The multimeter uses the power meter and a light source to determine issues related to fiber optic cable.

Test Cable

A test cable, also known as a reference cable[AA2] , helps detect issues within the cable and checks if the connectors are working well.

Fiber Optic Tracer

It is a low-power source of light used to trace fibers, identify splices, and other tests to see if there is any damage within the fiber.

Fiber Connection – Most Common Issues

Here are some of the most common problems you may encounter with fiber optic cables and their solutions:


If a fiber optic cable has been used for a long time, it is prone to damage in many ways. It will most likely twist or bend, which can affect its overall length.

The only way to fix its length is to replace it with a new cable. Make sure that your new fiber optic cable meets its length requirements. If you are unsure about its length, gather all the equipment and measure the distance while keeping everything in place to determine the length of the cable.

Fiber Damage

You can’t see if the fiber optic cable is broken or damaged inside through its outer appearance. To understand its internal condition, you can use a fiber optic tracer. It consists of an LED that joins the cable connector to see if there is any fault inside the cable.

If you can see the light from both ends of the cable, it indicates that the fibers are in good condition and there is no damage. However, if the fibers are damaged, you should ask a professional technician to fix or replace the fiber.


Often, fiber optic cables may stretch too much, which can potentially damage the cable. To resolve this issue, you can either combine all the cables or simply purchase a new cable with the right length.


Optic cords use connectors with fiber cables. If you are skeptical about their condition, see if the connectors fit well or not. If you detect any issues, you can fix them by fitting them properly. However, if it does not resolve, it is better to use a new cable that has spring-loaded connectors. This way, the connectors will be inserted into the cable seamlessly without the risk of slipping out.

External Damage

To ensure that your fiber optic cables perform well, you need to inspect them regularly. If you notice any scratches or splits inside the cables, then it is time for you to replace them with new ones.

Wrapping Up

Fiber optic cables are best for delivering fast internet speeds to establish a secure network for various homes and offices. However, it is susceptible to damage in many ways. From dust, humidity, scratches, and even fingerprints, any small factor can disrupt its performance to a great extent.

If you were planning to get a fiber internet connection for your home and it is not available in your area, then you don’t need to fret over it! Rural internet offers internet connectivity with minimal risks associated with external damage. So, go ahead and get yourself a much sturdier internet connection now!
