A 50-Second Skimmer into Fusion Splicing Process

Here’s a quick snapshot at the process of Fusion splicing. All it will take you is 50-seconds.

Fusion splicing definition
Fusion splicing is done for two ends of the fibre optic cables. It is similar to the welding process. The only difference in fusion splicing is that the materials involved are glass bunches and not metals. Like welding, the splicing is done by using localized heat. It could either be an electric arc or a laser shot.

Types of Fusion splicing
Depending on the splicing environment and the industrial application, fibre optic cable splicer machines are classified as:
-    Field Splicing Kit
-    Factory Fusion Splicer
-    Laboratory Splicer machine

There is another set of classification depending on the medium where splicing is done.
 For example, Marine fusion splicer machines are used for under-sea deployment submarines. Aerial fusion splice tools are used for space ships and aeroplanes.

Principle involved in Fusion splicing of Fibre optic cables
Before moving ahead with the fusion splicing, get familiar with the principals of:
-    Optical Wave Guide Theory
-    Heat Transfer
-    Glass property
-    Material Science
-    Fluid Mechanics
-    Static Dynamics
-    Stress Strain Energy Transformation
-    Mechanical Engineering
-    LASER

Features of Fusion Splicing
Fusion splicing used on fibre optic cables is a permanent alliance. Unlike the use of fibre optic connectors, the fused cables can’t be detached. The features associated with the fusion splicing are:
-    Quick operation that takes less than 30 minutes
-    Easy alignment if fusion splicer machine is used
-    It saves resources and cost-effective
-    Loss through the fusion spliced fibre optic cables is measured at less than 0.2 decibels across a length of   124 miles.
-    The strength of the fused site is impeccable.

Position of the Fusion splicing technique in the industry
In the digital age, it goes without saying that fibre optic cables form the connectivity face of the IT industry. In optical network, the precision of fusion splicing process can make or break business. Poor quality fusion splicing at the fibre optic cable ends could result in significant loss of data and interference during transmission. Loss of data or corruption means loss of revenue.
This is the exact reason why the best in the industry prefer to go with the fusion splicer machines. The fusion splicer machines are preferred over mechanical splicer for two reasons:
1.    Fusion splicer machines involve use of precision cleaving and alignment models
2.    The automatic dusting and removal of dirt and moisture is taken care by the fusion splicer machine

Objective of the Fusion splicing technique
The primary objective of the fibre optic fusion splicer technique is to achieve the same quality of physical and data transmission properties as the original cables. Closer the resemblance, higher will be the efficiency of the spliced cables.

Fusion splicing is done to achieve:
-    Impeccable physical strength without compromising on the quality of signal transmission
-    Elongation of the fibre optic cables without involving any fibre optic connectors
-    Long-term reliability in terms of signal transmission across a variable medium
-    Zero maintenance as far as replacement of fibre optic cables are concerned

5 Unassailable Pointers of a successful Fibre Optic cable Fusion Splicing

Did you know that the process of fusion splicing is just as old as the television? Why suddenly has it caught the interest of the IT leaders and Cloud technology providers? Well, the answer lies in the mega bandwidth demands and the dwindling copper resources. The age of connectivity and smart resource planning has prompted the companies to adopt fibre optic cables as their new go-to layout. From in-house architecture to outside plan applications, fibre optic cables are ruling the roost. And the fibre optic fusion splicing process is what stamps the seal of authority on the final architecture. How and why? We tell you in 5 quick ways.

- Permanent Fusion: Bend it around
Fusion splicer machines give the fibre optic cables the much needed flexibility that it lacks initially. Once the splicing is done, the two fibre optic cables are fused permanently. It does not break or crack even when passed around a corner. The flexibility of using a fusion splicer site eliminates the use of an additional kit of connectors.
 

With splicing in place, the fibre optic cables can be twisted, bent and even looped around.
 

- Elongate the Layout without Compromising on Bandwidth
Modern-day fibre optic cables carry signals at a bandwidth of more than 2.5 GBPS. This incredible capacity requires additional lengths. In most cases, a connector will suffice. It is economical to use a fibre optical cable bunch from the same family. It serves two purposes:
 

-    Increase the length of the wire to any desired magnitude
-    Strengthen the structural ability of the cable to sustain pressure in out-of-plant applications.

- Single Mode Splicing: Enhanced data centre capacity
If you are serving your clients with LAN service across long-haul OSP, the fusion splicer technique to connect two or more fibre optic cables becomes evident. It is usually done for the single-mode fibres as they have fewer glass-cores in bunch. At data centres, where the emphasis is on resource density and performance, the fibre optic cables are fused together using the fusion splicer machines.
 

- Simple Localized heating: No High-end resource tools
Fusion splicer machines are economical as far as pricing and effectiveness are concerned. Two fibre optic cables are joined using localized heat. The only care that has to be taken is with respect to the removal and re-covering of the outer shell around the glass core.

 

The fusion splicing is said to be 100 per cent effective if there is no hint of scratch, lips or grooves on the glass sheath. Moreover, the tube should be completely free from moisture and dust.
 

From angle of cleavage to alignment degree, the fusion splicer machine ensures that the two ends of the fibre optic cables are properly spliced to prevent any loss of signal at the site.
 

- Excepted loss tolerance: Less than 0.2 Decibels
A fusion splicing process is said to be a success if the resultant loss of data is found to be less than 0.2 decibels. It should be free from any moisture and dust. Two fibre optic cables can be fused at the cost of data loss.

5 Trendy Upgrades in the Fibre Optic Cable Splicing Machines

Fusion splicing of the fibre optic cables requires sophisticated technology with reliable tools. There are automatic splicing machines available in the market but they require skilled operators with years of technical expertise behind them. Contemporary technologies for fusion splicing have proven to be a reliable mechanism in producing long length connections. Most upgrades are made in the design and accuracy of the Profile Alignment System or PAS. Let’s study the various superior technologies that have been introduced recently in the fusion splicing of the fibre optic cables.
 

PAS with Dual Axis Camera Monitoring:
 

Fibre optic cable connections are very hard to deal with especially when you have long lengths to handle. Whenever there is slight interference in the connection due to bending or breakage of the fibre optic cables, it requires immediate fusion splicing. The recent introduction of the Fusion Splicer with an advanced PAS monitoring system allows the operator to make nicks with accuracy.
 

Advantages:
 

 o    The operator can handle multiple ribbon splicing. The fusion splicing machine with Dual Axis camera monitoring comes with a high resolution that accommodates up to 24-fibre ribbons.
o    The fusion splicer with camera vision allow the operator to clean and dust away the moisture and other impurities before splicing the fibre optic cables. It ensures highest accuracy of fusion.
o    The cost of installation is recovered in short period of time owing to higher quality of finished connections over the cables.
o    It ensures minimum loss of splices and prevents wastage. 

  

Automatic Arc Calibration:
 

Most operators find it hard to control the splicing over the arc of the fibre optic cable. The Automatic Arc Calibration technology prevents the slip of the fusion arc in smaller fibres. They can not only detect the ruggedness of the surface but also check if there is any groove. The splicing finish is judged using the Automatic Arc Measurement screen. It is often the final fusioning process and acknowledged as the industrial standard of finest smoothness achievable.
 

Auto-Start Spicing with Tube Heating:
 

The feed is controlled using the automatic start and stop command. The length of the fibre optic cable required to be spliced is fed in to the monitor. The software makes the adjustment in the clamp and splicer tips to accommodate the desired spicing length. The tube heating keeps the moisture away. The fusion splicing efficiency is measured in terms of amount of moisture present inside the glass surface and on the outer jacket or sleeve. 

Positioning in Zero-degree:

Some operations require the positioning of the fibre optic cables at zero degrees. This is particularly true of cases with the fibre optic connectors are used. In order to prevent the slipping of the connector and the funnel over the fibre cable core, the Zero-Degree Fibre Positioning kit is used. The PAS system is linked to the Zero Degree holder for more accurate operation. 

  

Software Updates:
 

The latest upgrades in the software are made using Internet firmware. These updates are offered by the fusion splicing machine manufacturers based on the membership.
