Tracing faults in fibre-optic networks

Data providers decided to replace the old cables with fibre optics because they offer increased performance. This type of cables was designed to meet high-performance requirements and nowadays everyone wants to have access to this type of network. If there are users who are not familiar with the fibre optic networks then they should know that both the installation and troubleshooting processes are different from the ones of copper cable. But when the optic fibre network faces an issue, human intervention is required in order to locate it. If the data network goes down because of a fault in the fibre optic cables then there are required some steps to identify it. Also, professional equipment is needed, because without it, it is impossible to find the break.

What can cause a fault in the fibre-optic cables?

Animals – people are aware that pests have the habit to chew through cables. Sometimes pets are the ones that damage the cables, without their masters even noticing it.

Vehicles – tall vehicles can damage the cables fixed aerially. In case the vehicle is heavily loaded, it can damage even the cables buried underground.

Weather conditions – even the well-protected networks can be affected by weather conditions like wind, ice, snow and rain. Natural disasters are the main cause when a network experiences damages.

Steps to identify the issues in fibre

Gather information

When trying to identify the cause of the fault in the fibre optic network, it is important to understand what its symptoms are. It should be checked if the devices connected to data were moved from the place where the tech team placed them during the fibre optic cabling installation. In case the devices were moved, it is important to verify if the cables were reconnected correctly. Sometimes the hardware part of the devices is the one that influences the functionality of the data, and the optic fibre has nothing to do with it. The cable’s connector should be checked to notice if it is damaged.

Make a test

In order to check if the optic fibre is damaged or broken, it is advisable to disconnect the both ends of the cable and to use a laser pointer to see if the light comes out in any place. Place the laser pointer light at one end, and if the light comes out at the other end, then the cable is not damaged. In case the user does not have a laser pointer, a bright flashlight can be used.

Extra diagnostic strategies

When trying to identify the faults in the data network it is advisable to use the elimination technique. After the user verifies the state of the fibre-optic cable with the help of a laser pointer, they should connect another device to the data cable to check its functionality. If the second device works, then the cable is functional and the issue has another cause. The main device may experience a configuration problem or it may run a firewall that prevents the device from connecting to the data network. If the second device is not able to connect to the internet, then the fibre cable may be damaged or the port where the cable is connected. It is the time to contact professionals!
