Techwin China Important Steps of Fusion Splicing Do you know that a fiber splicer offers varied benefits- from operating on a battery, to being compact and lightweight; the advantages of a splice machine are simply endless! Today, stateof-the-art splicers minimize setup time and are perfect for locations where space is tight. Furthermore, the total heater cycle and splice time is less than one minute, thereby helping technicians through various termination locations effectively.
Regardless of the type or quality of the splice machine you purchase, there are four vital steps involved in fusion splicing, namely preparation of the fibers, cleaving the fibers, fusing the two fibers and together and finally, protecting the splice. Let us learn about each in a comprehensive manner.
Preparing the Fiber: This includes stripping away the protecting coatings, including sheath, jacket and cladding. When the fiber contains only the bare glass, they are precisely cleaned. Here, cleaning is extremely important even minute dust or dirt particle can ruin the whole process.
Cleaving The next step involves cleaving the fiber. As the word refers, cleaving is not cutting. Instead, it implies scoring the fiber with the use of a cleaver and then flexing or pulling it till it breaks. The process of cleaving is also crucial as a faulty cleave can ruin a good splice, whereas a proper cleave will lead to a good splice.
Fusing the Fibers Now, when the process of cleaving is complete, the next step is fusion of the fibers. This process involves two steps, namely aligning and heating. The process of alignment can be automatic or manual, three-dimensional or fixed. This is usually done with the help of a viewer which enhances of magnifies the images of the fiber ends. Thus, they can be effectively positioned. The normal devices used for magnifying are optical power meters, viewing scopes and video cameras. In the process of alignment, the two ends of the fibers are perfectly matched to ensure that the light can easily pass from one fiber to the other with minimal loss, distortion or reflection. Once the process of alignment is complete, they are then burned or fused together via generation of a high voltage electric arc. It melts the fiber tips and thereby the fibers are fused together.
Protecting the Splice Finally, for the completion of splice, numerous splice protection techniques can be utilized, namely self-hardening silica, mechanical protectors and heat shrink coverings. So, use a splice machine to enhance effectiveness, reduce cost and ensure fusion of fibers in minimal time!
