Fiber splicing is the procedure of permanently joining two fibers together. Unlike fiber connectors, which are equipped for easy reconfiguration on cross-connect or patch panels.
Mechanical splicing doesn’t physically fuse two optical fibers together, rather two fibers are held butt-to-butt in a sleeve with a bit of mechanical mechanism. You will get worse insertion loss and back reflection in optical fiber ribbon machine in comparison to fusion splices (the 2nd type our company is introducing below). Mechanical splicing is mainly employed for emergency repairs and fiber testing. You can check out some mechanical splice products here.
Another type splicing is named fusion splicing. In fusion splicing, two fibers are actually welded (fused) together by an electric arc. Fusion splicing is easily the most popular means of splicing since it provides for the best insertion loss and hardly any back reflection. Fusion splicing provides the most trustworthy joint between two fibers. Fusion splicing is carried out by a computerized machine called fusion splicer (fusion splicing machines). We shall focus on fusion splicers within this tutorial.
Since we said above, fusion splicer may be the machine used to weld (fuse) two optical fibers together. This procedure is known as fusion splicing. The fiber ends are prepared, cleaved, and placed into alignment fixtures around the fusion splicer. In the press of a button, the fiber ends are heated with electrodes, brought together, and fused.
Fusion splicers are automatic machines you need to either choose factory recommended settings or else you set the splicing parameters yourself. There are five simple measures to fusion splicing having a splicing machine.
There are many types of fusion splicing machines available, varying in features and capability, and expense. So you must do your homework before making a choice. The next section describes different fiber alignment technologies in several types of fusion splicers.
Optical fiber core alignment (also known as “profile alignment”) secondary coating line use multiple cameras to inspect the 2 cleaved fibers before fusing and let for multiple axis movement of your fibers. The two fibers are illuminated from two directions, 90 degrees apart. In the multiple video cameras, the appliance recognizes the core from the fibers and aligns them automatically using movable stages.
Core alignment splicers are high-end units allow users to hold separate programs or recipes where factors for example splice some time and temperature might be highly customized. Such top end fusion splicers magnify and visually display the splice, and make use of active core-alignment to line up the fibers. Light injection technology and imaging software align the fiber cores so maximum light passes from a fiber on the other, ensuring minimal splice loss.
This gives for precise fiber alignment, creating a typical splice lack of only .02dB. This amount of precision is essential for all those single mode fiber applications as well as enhances performance of multimode fiber. Ribbon splicers typically use core alignment.
Core alignment fusion splicers have long been the most well-liked method for CATV installations, backbone networks, specialty fiber applications, and optical components manufacturing largely szzstrand of their high accuracy and reliability. The following picture shows a AFL FSM-60S core alignment fusion splicer.
More Optical fiber coloring machine employ clad alignments to line up the fibers for splicing. The fibers sit inside a holder or V-groove and therefore are lined up “physically”, based on the outer diameter in the fiber’s cladding. These splicing units are at the mercy of the fibers’ glass geometry characteristics and tolerances (Clad Diameter, Clad Non-Circularity, and Core-to-Clad Concentricity). Just because the outer diameters are aligned, doesn’t mean the cores will be perfectly aligned. Such units typically produce higher loss splices and do not have the features and suppleness of high end splicers.
Clad alignment splicers have multiple cameras but only provide for single axis movement of the fiber. Alignment is aided from a fixed v-groove. The normal loss for this type of splice is .05dB. Clad alignment splicers are best best for multimode applications. The subsequent picture shows a AFL FSM-16S cladding alignment splicing machine.
