mechanical fiber optic splicing
Step 1: strip the fiber
Fiber preparation here
The process is the same as the cleaving is practically the same as for fusion splicing. Just removing the protective coatings, jackets, tubes, strength members to show the bare fiber. Then ensuring the cleanliness of the fiber.
Step 2: cleave the fiberfor fusion splicing. It is necessary to obtain a cut on the fiber which is exactly at right angles to the axis of the fiber.
Step 3: mechanically join the fiber
In this step, heating is not used as in fusion splice. Simply connecting the fiber ends together inside the mechanical splice unit. The index matching gel inside the mechanical splice apparatus will help couple the light from one fiber end to the other.
Step 4: protect the fiber
Once fibers are spliced, they will be placed in a splice tray which is then placed in a splice closure. Outside plant closures without use of heat shrink tubing will be carefully sealed to prevent moisture damage to the splices.
Which Method is Better?
Both fusion splicing and mechanical splicing method have their advantages and disadvantages. Whether choosing fusion splice or mechanical splice depends on the applications.
The fusion one provides a lower level of loss and a higher degree of permanence than mechanical splicing. However, this method requires the use of the expensive fusion splicing equipment. In view of this, fusion splice tends to be used for the long high data rate lines that are installed that are unlikely to be changed once installed.
The mechanical splicing is used for applications where splices need to be made very quickly and where the expensive equipment for fusion splices may not be available. Some mechanical fiber optic splice easily allows both connection and disconnection. In this way, a mechanical splice may be used in applications where the splice may be less permanent.
Fiber optic splicing is an essential method in the installation of fiber optic networks. Choosing the suitable method, whether fusion splice or mechanical splice relying on its applications, can not only saves money but also improves efficiency. When doing fiber splicing, it is necessary to following the specific instructions strictly for perfect splices. Besides, keeping all splicing tools clean is also very important.
