Optic Cable Jacket used to identify cable type

Optic Cable Jacket is a vital part for any Fibre Optic Cable.

Optic cable jackets are used in almost every communications project. No matter whether it is a Base Station with wireless backhaul or a DAS installation, fibre optic cable jackets are used in that particular network for sure.

A general understanding of fibre optic cable jackets and different available types will help you select the right product for your project.    

Optic cable jacket colours

Fibre Optic cable jacket colours on patch leads are the easiest way to find out which type of cable you have at hand.

The colour yellow, for instance, identifies a single-mode cable; whereas, an orange coloured cable means it is for multimode purposes.

Although this might seem quite easy at first glance, the emergence of 10-Gigabit Ethernet and 50-micron, laser-optimised multimode cable technologies changed the entire scenario.

This gave birth to the need for differentiating new grades of optic cables from the older ones.

Another Fibre Optic Jacket colour

In this perspective, a new fibre optic cable jacket colour was introduced by Lucent Technologies.

The main aim was to set its new 10Gb/s laser-optimized 50-micron optical fibre cable apart from older 50 and 62.5- micron multimode fibre cabling, which is also known as orange.

If you think that the identification problem is solved at this stage, then you are completely wrong. Other competitors were also quick to adopt Lucent’s aqua jacket concept.

Unfortunately, not every manufacturer transitioned to this particular colour-identification system.

For this exact reason, aqua is also being used for 50-micron fibre cabling that is entirely different from TIA standards, when it comes to distance capabilities and performance.

Simply, aqua-coloured jacket can’t distinguish the exact performance of your optic cable.

There are, however, still some ways to know what you are dealing with.

What about Standards?

The TIA-598-C standard indicates that coloured-jacket cables are built solely for intra-building applications; while some optic cable jacket colours specify the varying degrees of fire resistance.

There are no outdoor cables in the TIA-598-C colour standard. This is because most of the cables used outside come with a black carbon component in their jackets, to protect them from harsh elements and solar radiation.

TIA-598-C covers the jacket-color standards which apply to optic cables with only a single type of fibre.

An optic cable containing more than one type of fibre cannot be distinguished through colours alone.

In this case, it is a must to have printed identification on the jacket for necessary identification.  


In order to ensure that you are buying the right product, you need to know a few basics and have done some research. 

This is the best way to make sure that you have the right fibre optic cable to get the job done!
