Optical Fiber Cleaving
2013年5月28日Article about Sumitomo FC-6S and Fujikura CT-30 fiber cleavers from FiberStore. Listed informaiton about what is fiber optic cleaver, why we need it and typical fiber cleaver designes(http://juneliao.blogdetik.com/2013/05/28/fiber-optic-cleavers-introduction/),etc.
Fiber optic fusion splicing is definitely needed once we want to fuse two optical fibers together for that continuity of fiber optic cable plant. However, within the optical fiber fusion splicing process, fiber tips have to have a smooth end face that’s perpendicular for the fiber axis. Sufficiently perpendicular and planar fiber end face can be achieved via the fiber cleaving process.
To put it briefly, a fiber cleaver is a piece of tools of kit to make a perfect fiber end face cut that may assure the quality of the joint of bare fibers inside the optic fusion process, leading to lower attention of the fiber connection line.
Within the fiber cleaving process, the fiber is pressed up against the little cut to make it to destroy at 90 angle and expose an image like fiber end face. The fiber is scratched using a very hard diamond edge scribing tool, which induces a big enough surface crack, then a fiber cleaver applies a tensile stress towards the fiber which caused the crack to expand rapidly throughout the fiber cross section. There are also kinds of fiber cleaves use the tensile stress first after which scratch the fiber with the diamond edge scribing tool. A quality fiber cleaver is extremely important in determining the fusion splicing loss. Many of the correct for a few special fibers including dispersion-compensating fibers and erbium-doped fibers.
A fiber cleave is initiated by lightly scratching the surface of the fiber. When the fiber is thereafter pulled or bent, a crack will originate at the scratch and propagate rapidly across the width from the fiber. This produces a nearly flat cleave of an optical fiber. Beneath the direction of this idea, there created a variety of commercial optical fiber cleaving tools in the market: Some cleavers apply a tensile stress towards the fiber while scratching the fiber’s surface with a diamond edge. Additionally, there are other designs scratch the fiber surface first, then apply tensile stress. Some cleaves use a tensile stress which can be uniform over the fiber cross-section while others bend the fiber trough a tight radius, producing high tensile stresses externally the bend.
Fiber optic cleaving tool is generally designed for cutting different number of fibers at the same time. Single fiber cleaver and ribbon fiber cleaver are typical. They work on the same principles but ribbon cleaver is for simultaneously cleaving all of the fibers inside a ribbon cable, which can be somewhat interior compared to that of a single fiber cleaver. Most today’s fiber cleavers are compatible with precision cleaving of common single silica glass fibers. Additionally, there are some special cleaver designed ones for applications including in research, measurement technology and output of optic components.
Under on-side conditions, most high precision cleavers produce a cleave angle deviation within 0.5° with very high reliability and low scattering. Diamond bladed is the highest cleaver quality and will last over 10,000 cleaves.
It is easy for a modern fiber cleaver to cleave a 125um diameter fiber, but difficult to cleave >200um fibers. This is especially turn when the fiber just isn’t crystalline. Besides, torsion will make a non perpendicular endface.
Typical brand for fiber optic cleaver are Fujiura, Sumitomo, Furukawa, etc. all of these kinds of these brand can be found at FiberStore.
Take Sumitomo FC-6S and Fujikura CT-30 for example. The CT-30 cleaver can be found fro either single or ribbon fiber splicing applications. It’s idea for FTTx applications and equally in the home in a splicing van or perhaps in a bucked truck. Using the 16-position blade yields 48,000 single-fiber cleaves, or 4,000 12-fiber ribbon cleaves beforerequiring replacement, as well as the built-in scrap collector conveniently stores fiber shardsuntil they could be safely discarded. The FC-6 cleaver is accessible with a single fiber adapter for 250 to 900 micron coated single fibers. This cleaver is straightforward for users to operate by removing or installing the one fiber adapter and alternate between mass and single fiber cleaving.
