We’re going to look at what is a splice and when do I need one the two main types of splicing. Fusion splicing and mechanical splicing the secret of a good splice. how do you actually do a fusion splice and where can I get a more detailed guide on all of this.

what is a splicing in simple terms?

 A splice is when you join the ends of two optical fibers together this should form a strong smooth connection so that when light passes through. It is not scattered or reflected back at this price point so there is minimal loss when might you need to do a splice. A splice can be a cost-effective and time effective solution.

When you need to attach a connector onto the end of a pigtail you need to make your payable longer. Or the cable becomes damaged so rather than replace the whole cable you want to cut out the damaged part and join the rest back together.

Two types of splicing

Fusion and mechanical splice

Fusion splice

A fusion splice the ends of the two fibers are melted or fused together to become one single cable. This creates a joint that if done correctly should be just as strong as the natural fiber.

The completed splice is usually covered by a heat shrink plastic sleeve which protects and strengthens the joint. How is this done here comes the technical part.

First and most importantly the fibers need to be stripped cleaned and cleaved precisely we’ll cover. This in more detail in our demonstration later to fuse the ends of the two fibers together you need heat normally in the form of an electric arc. 

Well according to encyclopedia calm an electric arc is a device in which an electric current. That’s a flow of electrons is caused to flow between two points separated.

Did you know that one example of an electric arc in nature is a lightning bolt the heats can also be provided by a laser s flame or tungsten.

Filament through which current is passed a fusion splicer is a piece of specialized equipment that can do all of this for you mass fusion splices can do a complete ribbon of fiber that’s up to 12 splices in one. Go we’ll show you how to use a single fusion splicer later.

Mechanical splice

The second type of splice is a mechanical splice. Where fusion splicing molds the ends of two fibers together to become one single fiber. Mechanical splicing is different it just aligns the two fibers. In the correct position and holds them precisely in place to allow the light to pass through. This is done by using plastic or glass.

Alignments leave just larger than the fibers themselves aided by the use of optical glue or index matching gel. At the joint to reduce loss and reflectance the fibers are not permanently joined. Together just held firmly in place so how is this done just like with the fusion splice.

The fibers need to be stripped cleaned and cleaved precisely for the mechanical splice. itself just purchase a commercially available mechanical splicing toolkit follow the manufacturer’s guidance.

On how to insert the fibers correctly and splice component and hopefully you’ll get the optimum results. There are many different types available. If you’re unsure so which is better well usually this comes down to a question of cost.

Use quantity and performance let’s look at the pros and cons of. Each a fusion splicing machine is more expensive than a mechanical splicing kit and involves a certain degree of training to use.

However the cost of an individual fusion splice is significantly lower than a mechanical splice once you’ve purchased the machine. That is a fusion splice if done correctly provides a continuous connection.

That’s offering a lower insertion loss typically less than 0.1 disabil lower reflectance and that’s a very high performance. This ensures a strong signal and better protection against cable failure the loss in a mechanical splice.

Usually higher typically between North Point 2 and not point 7 decibels and they have a higher reflectance. So from the previous screen your BS difference is that fusion splicing makes it one continuous fiber at the end whereas a mechanical splice is simply.

Just two fibers tightly and precisely held together. It is also preferable to use a fusion spliced with single mode fibers whereas the mechanical splice would typically be used for multimode fibers.
