3 Factors for Selecting Fibre-Optic Cables

When you invest in fibre-optic cables, you have to ensure that they will deliver the performance which you expect in the environment where they will be set. With the right cables, you will have a system which will function in an effective and cost-efficient manner in the short term and in the long term as well. Here are the three main factors which you need to take into consideration as a buyer.


There are two main types of fibre-optic cables. The multi-mode models are designed to enable the signal to travel in various modes. Basically, it can follow multiple different pathways inside the strand. The modern cables of this type use laser-optimised optical glass and vertical cavity surface-emitting laser.

There are also single-mode cables. They are based on laser technology which enables fast and secure data transfer. These models are especially designed for carrying signal along very long distances. That is why they are used in telephone and cable TV networks. If you want cables for creating a network within a building, you should consider multi-mode ones.


The diameter of the fibre-optic cable has a direct impact on its performance. That is why it has to be chosen with care. The most widely used multi-mode models give you two options – 62.5 microns and 50 microns. Currently, the models with 50-micron diameter are preferred. This is primarily due to the fact that they have greater bandwidth. You have to know that in the range of 50-micron models there are variations in the bandwidth as well. That is why you have to have a clear idea of your individual requirements in order to make the right choice.


There are various construction options to pick from. It is worth looking at the most widely used ones. The tight buffer fibre-optic cables are flexible and easy to terminate. That is why they are used indoors. There are three main sub-types in this category. The distribution cables are the most versatile. The simplex and zip cord ones are used primarily for back plane and patch cord applications. The breakout ones are used for directing terminations without junction boxes.

The cables with loose tube construction are used outdoors as they are stronger and more resistant to moisture. In this category, you will find armored cables, which are used for applications buried outside. There are ribbon cables which have a small diameter. The aerial cables are used on poles which are set outdoors.

Professional consultation is important when it comes to the selection of fibre-optic cables.
