How to perfect the splicing process - fusion splicing in 10 steps

Especially in times of growing demands in fiber optic networks, the process of splicing fiber optic fibers has been increasingly applied and required. Splicing with fusion splicers, in particular, has become an attractive method to quickly and easily connect fiber optic fibers. Using the proper tool allows to connect the individual fibers of fiber optic cables extremely professionally. However, there are a few points to keep in mind during the splicing process.

Our product expert for fiber optic technology explains the splicing process in 10 steps, points out what to watch out for, and recommends appropriate tools.

Splicing tutorial at a glance

Step 1: Cleaning the splicer and fiber holder
Thoroughly clean the splicer and fiber holder.

Step 2: Selecting the fiber holder
Select the fiber holder set up for the upcoming fiber type of the fiber optic cable. The most common fiber holders include 250-µ- and 900-µ fibers.

Step 3: Stripping and cleaning the test fiber
Open the loose tube of the installation cable using a loose tube tool. Then strip off the coating using stripping pliers. Finally, carefully clean the fiber.

Step 4: Calibration
Devices calibrate automatically, all you have to do is select the appropriate splice program.

Step 5: Stripping and cleaning the fiber to be spliced
For the splicing process, now strip the fiber to be spliced using the proper tool. Then clean it thoroughly.

Step 6: Cleaving process
The fiber is scored using a cleaver and broken at a 90° angle. Thoroughly clean the cleaver before use.

Step 7: Starting the splicing process
From the centre, insert the glass fiber into the splicer. Now use the mechanical precision adjustment device to join the two fiber ends with pinpoint accuracy. Then select the proper fiber type in the menu and start the splicing process at the touch of the button. Within just a few seconds, the integrated electrodes generate an arc that thermally welds the light-conducting cores of the glass fibers together.

Step 8: Was the process carried out successfully?
Test the quality of the splice connection by means of an insertion loss meter (peak programme meter) or an OTDR meter.

Step 9: Applying the splice protection
Apply the crimp splice protection to protect the fiber. In doing so, a crimping press must be used. Insert the spliced fiber optic cable, keep it straight and tensioned and apply the press.

Step 10: Inserting the spliced fibers into the splice cassette
Use a splice cassette to accommodate the excess fiber length. For proper positioning, distances with large bending radii are specified inside the cassette. At last, place the splice protection into the splice protection bracket.

Did you know? How to splice

During the splicing process, two fiber optic cables are seamlessly joined by thermal fusion. This usually takes place in a fully automated process carried out by a splicer: The pigtails and installation cables are connected with one another at their ends.
Advantage: It is a particularly quick and efficient method that allows to achieve excellent attenuation and reflectivity values. As a result, the quality of the transmission path is implemented in the best way possible.

For the installation of highly efficient fiber optic networks, we can no longer do without the splicing process carried out by a state-of-the-art splicer. Thus, this method plays an essential role during the establishment of FTTx connections, i.e. broadband expansion.
The splicing process allows to restore a clean connection in case cables are accidentally cut.
