Step-by-step Teach You How to Splice Optical Fiber

With the rapid development of fiber optic network, the traditional 10M and 100M speed has been increasingly unable to meet the needs of people’s daily learning and work. Users are eager to improve the speed of networks.

1000M is a target for twisted pair cables, although we can use Cat6 cable to meet 1G transmission needs, but the production of Cat6 cables is very troublesome, and they also need very high demands on both ends of the connection equipment, while the various decay parameters requirements can not be reduced. Therefore, the most effective medium, which can break the 1G transmission speed, is still the optical fiber. This article will introduce how to use the tools to splice the broken fiber and pigtail, to meet the actual demand.

When should fiber optic splicing be conducted?

Everyone should know that fiber is very long, but any cable will encounter the problem of inappropriate length. So is fiber in this case, and it is time on the need for the fiber crop. Fiber is one entirety in the outdoor transmission, but when connected to the central office, the line the inside of the core needs to be connected separately, then we also need to splice the optical fiber. Therefore, the result is that fiber optic splicing is used in many places, and when we use optical fiber there must be some splicing problems.

How to splice optical fiber?

Fiber splicing is a high technical content in the past. They will get paid $ 500 in the previous work splicing a fiber core, while now only ten percent, I am afraid. Here I will step-by-step introduce how to splice isolated fiber together. However, there are only a lot of theory things, to truly grasp you should do it by your hands.

Step 1: Preparing

Fiber splicing needs not only professional splicing tools, but also a lot of common tools to assist in this task, such as scissors, vertical knife.

Step 2: Installation

Usually we are fixed optical fiber through the optical fiber accommodating box, the outdoor access to the optical fiber wrapped with black protective sheath from the rear of the storage box interface into the optical fiber receiving tank. Fibre Fibre asylum box will surround and fixed good to prevent everyday use loose.

Step 3: Peeling

First black fiber appearance peeled, probably removed about 1 meter long.

Then use a utility knife to remove the protective layer of the fiber. Paying particular attention to the fiber core with glass fiber production, easily broken, once broken can not be normal transmission of data.

Step 4: Cleaning

No matter how careful we peeled work also can not guarantee that the glass without any pollution, so we must be cleaned on the glass before the start of the splicing work. The more common method is with a paper towel stained with alcohol, then wipe clean every little fiber.

Step 5: Socketing

After cleaning, we give the need to splice two optical fibers are each put fiber heat-shrinkable tubing, the fiber thermal sleeve is mainly used in the glass fiber is good docking sleeve at the connection, and a new protective layer is formed after heating.

Step 6: Splicing

The stripped ends exposed glass fiber, optical fiber is placed in the optical fiber fusion splicer.

Then, the glass fiber fixed, press the SET button to start splicing. From fiber splicing display can see both ends of the glass-fiber butt, not too crooked instrument will automatically adjust to is, of course, we can also through the button X, Y, manually adjust the position. Wait a few seconds after the completion of the optical fiber splice.

Step 7: Packing

Splicing finished fiber glass wool exposed on the outside, it is easy to break. This time we can just put fiber heat shrink tubing fixed. Will a good set the fiber fiber heat shrink tubing on the heater “HEAT” key to start heating than 10 seconds you can out, thus completing a wire core splicing work. Finally also need to weld the good optical fiber placed and fixed in the optical fiber receiving tank.


The fiber optic connection is a practice that is not to look at the others to weld once or twice will be able to master, and only you have the appropriate equipment after professional training in order to more quickly and more accurately weld both qualitative and quantitative fiber. Then this introduction to splicing process only hope to help you readers in the future of work and study, can be considered rich insight and experience.
