How to Splice Optical Fibers and What Equipment Do I Need?

This article will tell you basics of fiber optic splicing which is a useful way of joining two optical fibers with the use of fusion splicers.

The Secret of Fiber Optic Fusion Splicing

Even if you ask children, how to join two metal parts together, they will tell you that this requires a splicer. Despite everyone being familiar about welding metals, only some engineers have an idea of connecting two fiber optic cables. If you are one of those who still doesn’t know about methods of fusion splicing – you are welcome to find out more about it.

What Is Fusion Splicing?

Fusion splicing has become popular with the further development of the Internet. Fiber optic transmits video signals better than metal, so all providers started using it as an appropriate material for faster communication. Two parts of fiber can become connected after using the method of high-temperature splicing performed by fusion devices. Now they seem much more complicated than tools used for metals and the process of splicing includes 4 main stages:

  1. Stripping the fiber: the first thing an engineer needs to do before the actual splicing is to free it from polymer coatings. Like for a metal wire, this coating is made for safety issues, but a technician needs to remove it if he wants to do something with its inside;
  2. Cleaning the fiber: an engineer needs to be sure that no extra details will take part in the splitting. If nobody does that carefully, the splitting might become dangerous, and extra parts might cause a lot of problems;
  3. Cleaving the fiber: the only way to get a quality splicing is to make both parts perfectly flat and perpendicular to an axis of your fiber. If an engineer doesn’t cut both parts, the splitting will not seem lasting;
  4. Splicing fibers: this part is the most dangerous and requires a lot of expensive equipment including a fiber optic fusion splicer.

Actual splicing comes within seconds when a bright spark bursts and two parts splice together with the help of a nichrome wire. This burst may be dangerous if you work in an environment full of explosive materials. It may also become dangerous if you don’t obey safety rules while working.

What Should You Know to Make Better Splices?

A company may buy an intrinsically expensive fusion device and spend much money on training, but splicing still may be dangerous. What is wrong with the quality? How to use a fusion splicer without causing so many problems? There are three hints professionals use to make their splicing job more careful:

Use a microscope to clean your wire: your fiber can be so thin that you will not see any defects and unnecessary details with a naked eye. You should be very careful while
