Secondary Coating Line – Check Out The Majority of Existing Options Whenever You Are Examining Optical Fiber Coloring Machines.

Fiber splicing is the method 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 the sleeve with a few mechanical mechanism. You will definitely get worse insertion loss and back reflection in FTTH cable production line when compared to fusion splices (the second type our company is introducing below). Mechanical splicing is mainly used for emergency repairs and fiber testing. You should check out some mechanical splice products here.

Another type splicing is called fusion splicing. In fusion splicing, two fibers are literally welded (fused) together by a power arc. Fusion splicing is considered the most popular approach to splicing mainly because it provides for the smallest insertion loss and almost no back reflection. Fusion splicing delivers the most dependable joint between two fibers. Fusion splicing is done by an automated machine called fusion splicer (fusion splicing machines). We will give attention to fusion splicers in this particular tutorial.

Since we said above, fusion splicer is the machine used to weld (fuse) two optical fibers together. This procedure is named fusion splicing. The fiber ends are prepared, cleaved, and positioned in alignment fixtures on the fusion splicer. On the press of the mouse, the fiber ends are heated with electrodes, brought together, and fused.

Fusion splicers are automatic machines that you have to either choose factory recommended settings or you set the splicing parameters yourself. There are actually five steps to fusion splicing by using a splicing machine.

There are many designs of fusion splicing machines available, varying in features and capability, and expense. So you should do your research before making a decision. The next section describes different fiber alignment technologies in various kinds of fusion splicers.

Optical fiber core alignment (also known as “profile alignment”) secondary coating line use multiple cameras to examine both the cleaved fibers before fusing and permit for multiple axis movement of your fibers. The 2 fibers are illuminated from two directions, 90 degrees apart. Through the multiple video cameras, the equipment recognizes the core of your fibers and aligns them automatically using movable stages.

Core alignment splicers are high-end units allow users to keep separate programs or recipes where factors including splice time and temperature may be highly customized. Such top quality fusion splicers magnify and visually display the splice, and utilize active core-alignment to align the fibers. Light injection technology and imaging software line up the fiber cores so maximum light passes in one fiber for the other, ensuring minimal splice loss.

This gives for precise fiber alignment, producing a typical splice loss of only .02dB. This degree of precision is needed 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 always been the most preferred way of CATV installations, backbone networks, specialty fiber applications, and optical components manufacturing largely szzstrand with their high accuracy and reliability. These picture shows a AFL FSM-60S core alignment fusion splicer.

More Sheathing line employ clad alignments to align the fibers for splicing. The fibers sit inside a holder or V-groove and therefore are arranged “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). Even though the outer diameters are aligned, doesn’t mean the cores will likely be perfectly aligned. Such units typically produce higher loss splices and do not have the features and adaptability of more expensive splicers.

Clad alignment splicers also have multiple cameras but only enable single axis movement of your fiber. Alignment is aided by way of a fixed v-groove. The common loss for this kind of splice is .05dB. Clad alignment splicers are best designed for multimode applications. The subsequent picture shows a AFL FSM-16S cladding alignment splicing machine.
