The quality of the obtained cleaves has different aspects, the relevance of which depends on the application: Sumitomo Electric sees it very important to provide professional after sales service to our valued customers. The encyclopedia covers this topic well: with a long overview article on laser material processing and specialized articles on Since fracture is such a violent and difficult to control process, even the best commercial cleaver will sometime produce defective cleaves. Newport offers electronically tuned ultrasonic blade cleavers - the FK11 flat cleaver and FK12 angled cleaver. They are suited for both singlemode and multimode fibers.
In the past, the difficult process of blade rotation adjustments has necessitated increased service and maintenance of the fiber cleavers due to the frequent improper cleaver blade rotation and height adjustments. The ultrasonically vibrating blade moves slowly toward the tensioned fiber on stictionless damped bearings. Cleaving then takes place without damage from compressive stresses and blade intrusion into the fiber that is typical of conventional cleavers. The downside to these built-in cleavers is that if either the cleaver or splicer requires maintenance, the technician loses two valuable tools, which can hold up the job at hand. Cleavers, like fusion splicers, continue to evolve with new and improved features, such as automated fiber scrap collection, automated scoring mechanisms, and the latest automatic blade rotation technology.Cleavers that are designed for fusion splicing require a low average angle that is one degree or less, while cleavers appropriate for mechanical connectors require angles below three degrees. Determine whether you require a single- or multi-fiber cleaver that can precisely cleave one to 12 fibers at a time. SumiCloud™ is a powerful tool that supports your fusion splicer in the field. Using your smartphone, your splicer connects to the internet and Sumitomo's cloud services which include data management, asset management, firmware updates and maintenance support. Enjoy a new generation of splice experience with SumiCloud™.
When we need to join two optical fibers together, we usually use mechanical splice or fusion splice. Note that it is often very worthwhile to carefully inspect fiber cleaves before using them, as later on it may be much more tedious to locate a fault. Even with a mechanical precision cleaver, the results may not be fully reliable because they require correct settings and can be spoiled by a defect blade, which is not easy to recognize. Additional Treatment: Polishing By purchasing from reputable manufacturers, you’ll enjoy manufacturer support and warranties; service for periodic maintenance and cleaning that extends the life of the cleaver; and a cleaver made of the best durable metal materials. These products target at applications where a consistent, defect-free, but angled cleave is required, such as for semiconductor laser diode manufacturing. Cleaving is the standard method to obtain such surfaces, or sometimes the first step towards that goal. It is a process of controlled breaking of the glass of a bare fiber. It begins with making a tiny fracture (scratch) on the side of the fiber, e.g. with a sharp diamond, carbide or ceramic blade, before or while some defined tension or bending is applied to the fiber. This causes the fiber to break, starting at the mentioned fracture point: the fracture rapidly propagates over the full fiber cross-section. Often, the cleaving leads to a very clean surface of the obtained two fiber parts.A fiber cleaver utilizes an automatic anvil drop for fewer required steps and better cleaving consistency. The automated anvil design can save time and significantly improve the quality of the cleave by eliminating human error and subpar cleaves associated with scribes and manual cleavers. To perfectly cleave optical fibers, perform the following steps: To ensure our customers can always use our fusion splicers, fibre cleavers, and other accessories at the highest performance level.
User Selectable Blade Rotation Options Include: Automatic Blade Rotation with Each Fiber Cleave,No Rotation, and Single Position AdvanceSumitomo is most well known for their consistently high-quality fusion splicers which are now considered standard equipment by many technicians and engineers in the fiber optic field. A microscope may be required to properly inspect the obtained fiber surfaces. There are hand-held microscopes for such purposes, and fusion splicing apparatuses also often contain a microscope. After lightly scoring the fiber, pull the fiber straight away from the connector to finish the scribe process. The fiber should shear cleanly at the scribe point. Cleaving is the process by which an optical fiber is “cut” or precisely broken for termination or splicing. Just like cutting glass plate, fiber is cut by scoring or scratching the surface and applying stress so the glass breaks in a smooth manner along the stress lines created by the scratch. Properly done, the fiber will cleave with a clean surface perpendicular to the length of the fiber, with no protruding glass on either end. There are laser-based devices (containing a CO 2 laser) which allow the preparation of fiber ends as an alternative to cleaving. Strictly speaking, the used process is not cleaving (which is a mechanical breaking process) but rather something like laser cutting. Nevertheless, it has become common to name it laser cleaving because it produces similar results.
