Principles and notes of mechanical splice
■ Principles of mechanical splice
Mechanical splice utilize mechanical splice elements as shown in the Figure 1. The internal structure is shown in Figure 2. The fibers are aligned on the V-grooves, and are fixed by upper body, then are being well maintained spliced. The index matching gel is applied at the center of the V-groove, where the fibers are spliced. The index mathcing gel supprts the low reflection and good splice condition.
When inserting the fibers, as illustrated in Figure 3, a wedge is inserted into the mechanical splice element, increasing the spce between upper and lower body, then allowing fiber insertion.
The fibers are introduced from both sides of the element, upon contact and remove the wedge, they are secured by the pressing by U sleeve.
■ Important points of mechanical Splice
There are 3 possible causes of high splice loss; (1)The fiber end face not contact, (2) Presence of foreign substances in the mechanical splice element and (3)Poor condition of the fiber end. It is important to understand and follow the correct oprationg procedure.
