Know Different Things About Aerial Fibre Optic Cables

Aerial fibre optic cables are very important part of any optical communication networks. These cables are very frequently used in our day to day life, e.g. hanging in any pole just in front of any house. But how much you really know about these aerial cables? By reading this write up, you can learn something about them.

Since the aerial fibre optic cables are usually exposed in the outside environment, they must be fixed on any fiber optic cable clamp which are made of material that is much different from conventional fibre optic cables, so that it can withstand windy, icy, rainy and snowy weathers. Also, the installation technique is much different from any other cables.

Types of aerial fibre optic cables

By methods of installation, aerial fibre optic cables are usually classified as 2 types:

1. Catenary wire
2. Self-supporting.

Cables of catenary wire aerial is like any common outdoor loose cables which can utilize its existing overhead pole to install, so that it can save the construction costs and also shortens the time for construction. Any cable of self-supporting aerial purpose or All-Dielectric Self-Supporting (ADSS) cable, which has bonded cable with an insulated steel for support. This ADSS cables are made of much heavier jackets with stronger metal. Nowadays, this self-supporting aerial fibre optic cables are widely used by everyone and the mostly used ADSS cables having figure 8 cable clamp.

Figure-8 aerial cable

Any figure-8 aerial cable can greatly simplify the task of keeping fibre optic cable on any aerial plant. This figure 8 cable incorporates both steel messenger and also the core of any standard optical fibre cable into one jacket having a cross section of "Figure-8". This combination of optical fibre and strand into one cable allows rapid single step installation and result into sturdier aerial plant. Such figure-8 aerial cable generally is used between two poles.

Drop Cable

Fibre optic cable of another type, intersecting face of that showing the shape of 8, which is called drop cable. One should not muddle them together in any cable clamp factory

Due to emergence of different access networks, which includes fibre to the business, or fibre to any home and fibre to the premises, are referred to as FTTx, which demands any new optimized products for meeting increasing bandwidth requirements that are daily increased.

Optical drop cable is one such product. This conventional drop cable will consist of 2 parallel strengthened core and also an optical fibre in the centre of them. Intersecting surface present 8 figure. Drop cables are widely used in any FTTH networks.

Self-supporting drop cable

Add any thick steel wire to this conventional drop cable, then the self-supporting kind of drop cable will be formed. Any self- supporting drop cable will have much stronger tensile strength due to its units of metal hanging. Therefore, they can also be called aerial drop cable.

This aerial drop cable can run from distribution point to any subscriber. This metal unit shall be clipped much before going into the subscriber. Biggest problem for any aerial drop cable can be that, it can be more expensive as compared to conventional drop cables.
