About this deal

The 16-position blade yields 60,000 cleaves, resulting in extended intervals between blade replacement. The CT-58 is designed for use with either Fujikura FH-100 or FH-70 series fibre holders but can also be used with the optional adapter plate to eliminate the need for fibre holders, if desired. When used with the optional spacers for the cleaver and RS-03 thermal stripper, six different cleave lengths can be easily attained. optical fibre type, the blade condition or the operating environment may affect the cleaving angle. Since the measuring device has been changed from an interference microscope to a fusion splicer, this specification value is now higher than that of the previous model (CT-30). The COFI-OSP course is designed for installation and maintenance staff working on core telecom fibre optic networks. On the COFI-OSP course you will learn to prepare fibre optic cabling for splicing within splice closures and ODFs and learn to terminate fibre optic cables by splicing on pre-terminated pigtails or splice on connectors in an ODF.

On OTT’s Certified Optical Fibre Installer (COFI) courses you can use a range of different tools and learn about common cleaving problems and their causes. After the course it is good to practice and practice is free of charge.

A somewhat reduced fiber tension during the cleaving process may help. Double-clad fibers with an air cladding are particularly challenging.

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:

Optimized for cutting up to 72 fibre MT and MT-APC ferrules as well as SMA connectors with larger fibre diameters Before cleaving, a fiber coating needs to be stripped off with a coating stripper tool, or dissolved with a suitable solvent. The latter technique – chemical stripping – may be required in problematic cases, but takes more time. Thermal stripping may be another option. Furukawa Electric Co., Ltd. was founded in 1884 and since that time has played a dominant role in the growth of the global marketplace. G. Van Steenberge et al., Laser cleaving of glass fibers and glass fiber arrays. J. Light. Technol. 23, 2 (2005) 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.The optimum settings of a mechanical fiber cleaver – in particular, the applied tension – substantially depend on details like the glass materials and the fiber diameter. Often, fiber cleavers are pre-adjusted for silica fibers with the standard diameter of 125μm. For fluoride fibers or other mid-infrared fibers, for example, one may have difficulties finding suitable parameters for repeatable cleaving results. M. Janna Vassantachart, M. Lightfoot, A. Yeo, J. Maldonado, R. Li, M. Alsyouf, J. Martin, M. Lee, G. Olgin, D. Duane Baldwin, Laser fiber cleaving techniques: effects on tip morphology and power output. J. Endourol 29, 84 (2015)

Fiber cleaving is an important technique in the area of fiber optics. When optical fibers are connectorized, when they should be fusion-spliced or when light should be launched into fibers, the fiber ends need to be prepared such they have clean surfaces. Usually, such surfaces should be as flat as possible, at least over the area of the fiber core (sometimes over the full cross-section), and often it is important that the surface is either perpendicular to the fiber axis or has a well-defined angle against the fiber axis. In the field of fiber optics, it is very necessary to use fiber optic cables with clean and smooth end face. The fiber optic cleaver is a crucial tools for low-loss and low-reflectance fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices. The fiber cleaver usually work in conjunction with fusion splicers to do optimum splicing jobs, and is the key to quality connectors and splices. What Is Cleaving and Fiber Cleaver? M. Okada, M. Kihara, M. Hosoda, and M. Toyonaga, “Simple inspection tool for cleaved optical fiber ends and optical fiber connector end surface”, in Proceedings of the 60th IWCS (2011). M. Kihara, M. Okada, M. Hosoda, T. Iwata, Y. Yajima, M. Toyonaga, Tool for inspecting faults from incorrectly cleaved fiber ends and contaminated optical fiber connector end surfaces. Opt. Fiber Technol. 18, 470 (2012) C. Paviolo, S. Jayawardhana, S. A. Wade, and P. R. Stoddart, Angle cleaving optical fibers using a CO2 laser”, In: 35th Australian Conference on Optical Fibre Technology, ACOFT 2010 ( 2010).Fibers with particularly large diameters, e.g. beyond 200μm, can also be difficult to cleave. They need a higher tension force. Warranty: One year or 600,000 cuts, whichever comes first when cutting 12-fibre epoxied MT ferrules Note that cleaving is not cutting, as the bulk of the process is just breaking. Only the initial tiny break is prepared with a blade. 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. The scribe or manual cleaver, which is cheaper than the precision cleaver, is the most original type of fiber optic cleaver. Scribe cleavers are usually shaped like ballpoint pens with diamond tipped wedges or come in the form of tile squares. The scribe has a hard and sharp tip, generally made of carbide or diamond, to scratch the fiber manually. Then the operator pulls the fiber to break it. Since the breaking process is under manual control, it is hard to control the force, which makes the cleaving less accurate and precise. That’s why most technicians shy away from these cheap cleavers. Precision Cleavers

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. Conversely, if the Fresnel reflection of a fiber end needs to be exploited (e.g. for building a fiber laser), it is important to keep the cleave angle small – well below the beam divergence angle corresponding to the fiber mode. Large mode area fibers are more critical in this respect.

Judging the Cleaving Results

Instruction Manual for High Precision Fiber CleaverCT-30 Series”, URL: https://shop.nag.ru/uploads/CT-30%20new%20manual.pdf. Steps of Fusion Splicing Fiber Optic Cables, URL: https://telecom.samm.com/steps-of-fusion-splicing-fiber-optic-cables. Sumitomo 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. And an optical fiber cleaver is the tool to cut (called cleave in the fiber optic industry) the fiber in such a good way. 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.
