Optical Fiber Splicing Pdf
Within mechanical splicing you need the proper angle to insure proper end faces or too much light escaping into the air gaps between the two fibers will occur. Fusion splicing produces lower loss and less back reflection than mechanical splicing because the resulting fusion splice points are almost seamless.
Fusion splices offer a lower level of loss and a high degree of permanence. First the ends if the cable are inspected using a magnifying viewer.
High time and low current result in the same outcome as high current and low time. Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it.
Protect the fiber - the completed mechanical splice provides its own protection for the splice. Fuse the fiber - There are two steps within this step, alignment and heating.
Because it provides the lowest loss, less reflectance, strongest and most reliable joint between two fibers. So a mechanical splice can be used in not permanent situations. Thoroughly and frequently clean your splicing tools. Tips for Fiber Splicing and Termination.
Fiber Optic Splicing Fusion Splicing Method
However this comes at a process as fusion welders for fibre optic splices are very expensive. The two types of fibre optic splices are used in different applications. They are illustrated in following one by one.
However they require the use of the expensive fusion splicing equipment. The ends of the fibre optic cable are then cut, or to give the correct term they are cleaved with a precision cleaver to ensure that the cuts are exactly perpendicular.
Cleave the fiber - Using a good fiber cleaver here is essential to a successful fusion splice. Mechanical and fusion splices The two types of fibre optic splices are used in different applications.
Dirty equipment should be your first check and them continue with the parameters. If you have a poor cleave the fiber ends might not melt together properly causing light loss and high reflection problems. It is a preferred solution when an available fiber cable is not sufficiently long for the required run. One of the most common occurs when a fibre optic cable that is available is not sufficiently long for the required run. In case they are accidentally broken.
We carefully seal shrink tubing to prevent moisture damage from the splices. Some of the sleeves for mechanical fibre optic splices are advertised as allowing connection and disconnection. The location spark and the energy it contains are very closely controlled so that the molten core and cladding do not mix to ensure that any light loss in the fbre optic splice is minimised.
This paper firstly illustrates the specific process of fusion splicing method and mechanical splicing method. This is achieved by directing light through the cladding on one side and measuring the light leaking from the cladding on the other side of the splice. They are accurately aligned to maximise the level of light transmission and then they are clamped in place.
That said, some manufacturers do offer fibre optic splices that can be disconnected, but nevertheless they are not intended for repeated connection and disconnection. Preparing the fiber - Strip the protective coatings, jackets, tubes, strength members, etc. If you start changing the fusion parameters on the splicer as soon as there is a hint of a problem you might lose your desired setting.
When splices need to be made very quickly and the expensive equipment for fusion splices are not available. The mechanical splices are normally used when splices need to be made quickly and easily. In view of this they tend to be used more for the long high data rate lines that are installed that are unlikely to be changed once installed. Click here to see our Fiber Splicing Kit and let us help you find the right tools for all your fiber optic needs.
Mechanical Splicing Method Mechanical splicing is an optical junction where the fibers are precisely aligned and held in place by a self-contained assembly, not a permanent bond. Fusion Splicing Method As mentioned previously, volvo xc70 owners manual pdf fusion splicing is a junction of two or more optical fibers that have been permanently affixed by welding them together by an electronic arc. Fusion splicing is a permanent connection of two or more optical fibers.
Fiber Optic Splicing Two Important Methods for It
Thank you for doing your business with Tecra Tools and we look forward to serving you soon! It is noted that the cables should be clean. The mechanical splicing is often used in these situations.
The other, more common, method of joining fibers is called termination or connectorization. Home Fiber Optic Splicing Guide. The fibers are in a premises installation. Fusion time and fusion current are the two key factors for splicing.
We need to Choose fusion splice or mechanical splice depends on the applications. When you do fiber splicing, you need to follow the specific instructions strictly for perfect splices. Then the area to be spliced is cleaned of any dust often by a process using small electrical sparks. Besides, keeping all splicing tools clean is also important. Alignment can be manual or automatic depending on what equipment you have.
Tecra Tools offers a large selection of fiber optic tool kits and fiber optic supplies. The cleave end-face should be perfectly flat and perpendicular to the axis for a proper splice. This type of splice uses an electric arc to weld two fibre optic cables together and it requires specialised equipment to perform the splice. Fusion parameters must be adjusted minimally and methodically fusion splicing only.
The fusion splicing provides a lower level of loss and a higher degree of permanence than mechanical splicing. The cleaved end must be mirror-smooth and perpendicular to the fiber axis to obtain a proper splice. There are many occasions when fibre optic splices are needed.
