Fusion Splicing: The Simple Welding

Process for Optic cables

Optic fibre cables have changed the way we see at our electronics these days. While the fibre optic cables are virtually flawless, sometimes it becomes necessary to break the lines and rejoin at certain places. We have heard how a glass once shattered can’t be fixed back. Well, the optics fibre cables that are made of glass materials are an impressive exception to this fact. The fibre optic cables can actually be joined at ends using a special process called Fusion Splicing.

When to use Fusion splicing technique?

Fusion splicers are used to join the ends of two fibre optics. It is usually done by using an electric arc tip. Modern technologies employ laser welding techniques too for a more clear fusion splicing amalgamation. The fusion splicing method is used in following conditions:

o When a certain part of the fibre cable breaks or cracks

o When the fibre cable portion creates undue resistance to the flow of data or electricity

o When the length of the layout is supposed to be enhanced to connect more points

Why use fusion splicing?

Fusion splicing is the most cost-effective technique used to join two or more fibre optic cables without damaging their physical attributes. Fusion splicing is done due to the following advantages:

–It has 100 per cent reliability– It prevents loss of data due to joining barriers–It offers least order of reflectance–The Fusion splicing ensures highest order of strength and durability– It is applicable for both single mode fibre optic cables as well as the multimode ones.

Difference between Single Mode and Multimode Splicing

All single mode fibre optic cables are actually connected using fusion spicing. When it comes to linking two multi-mode fibre optic wires, the fusion splicing technique becomes a little tough. The fusion splicing in multimode optic cables is harder owing to the larger core diameter and the multiple layers of glass that creates a gradient profile. Fusion splicing for multimode cables is costlier and more sophisticated as the process involves the matching of the individual gradient of each of the inner layers.

Types of Fusion Splicing

Based on the volume of cables joined, there are two types of Fusion splicing methods for optic cables. They are:–  Single Fibre Fusion Splicing (Usually for Single mode cables)–    Ribbon splicing (For multimode cables)

Fusion Splicing using Automation Tools

Fusion splicing machines are laced with fully-automatic tools that helps pre-set the fibre optic cables for welding purposes. Based on the requirement, the machine allows the operator to choose various splicing parameters and ensure closest approach towards perfect joining. The fusion splicing machines come in two setting models:

– Automatic settings–    Factory-based settings
