Other uses Strip disambiguation Strip Stripping is the act of removing the protective polymer coating around optical fiber in preparation for fusion splicing . The splicing process begins by preparing both fiber ends for fusion, which requires that all protective coating is removed or stripped from the ends of each fiber. Fiber optical stripping is usually carried out by a special stripping and preparation unit that uses hot sulphuric acid or a controlled flow of hot air to remove the coating . There are also mechanical tools used for stripping fiber which are similar to copper wire strippers. Fiber optical stripping and preparation equipment used in fusion splicing is commercially available through a small number of specialized companies, which usually also designs machines used for recoating fiber optical recoating .

Fiber In The Loop FITL is a system implementing or upgrading portions of the Plain old telephone service POTS local loop with Optical fiberfiber optic technology from the Telephone exchange central office of a telephone carrier to a remote Serving area interface SAI located in a neighborhood or to an Optical Network Unit ONU located at the customer premises residential and or business . Generally, fiber is used in either all or part of the local loop distribution network. FITL can be implemented with any FTTx architecture, such as fiber to the curb FTTC , fiber to the node FTTN , and fiber to the premises FTTP . Residential areas already served by balanced pair distribution plant call for a trade off between cost and capacity. The closer the fiber head, the higher the cost of construction and the higher the channel capacity. In places not served by metallic facilities, little cost is saved by not running fiber to the home. A similar network called a hybrid fibre coaxial HFC network is used by cable television operators but is usually not synonymous with fiber In the loop , although similar advanced services are provided by the HFC network.

A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat endface, perpendicular to the longitudinal axis of the fiber. Since there are no crystalline planes in glass , this process is not cleavage crystal cleavage in the crystallography crystallographic sense of the word, although the techniques used and the finished result are quite similar. A cleave is made by first introducing a microscopic fracture nick into the fiber with a special tool, called a cleaving tool , which has a sharp blade of some hardness hard material, such as diamond , sapphire , or tungsten carbide . If proper Tension mechanics tension is applied to the fiber as the nick is made ... cleave is required for a successful splice of an optical fiber, whether by Fusion splicing fusion or Mechanical splice mechanical means. Also, some types of fiber optic connector s do not employ abrasives and polishers. Instead, they use some type of cleaving technique to trim the fiber to its proper length, and produce a smooth, flat perpendicular endface. High precision optical fiber cleavers ...

Mechanical cleavers clamp the fiber in the correct position before a diamond wheel or blade scribes the fiber. Then, a force is applied and the fiber gives a nice break at the scribe. Mechanical cleavers give nicer and more repeatable cleaves. Multifiber cleavers are used for ribbon fiber cables.

Unreferenced date December 2009 Orphan date February 2009 Fiber simulation is a branch of mechanics that deals with modeling the dynamics mechanics dynamics and rheology of particles of large aspect ratio, or fibers with the goal of predicting the properties of fiber suspensions and networks based on first principles . Simulation of fiber suspensions have applications in paper industry and also in Composite material composites , including composites made of carbon nanotubes . Many of the models used to simulate fibers were developed by researchers in the field of rheology . Rheologically speaking fiber suspensions are non Newtonian fluid s, and can display normal stress differences. Early fiber simulations employed particles which were rigid rods or prolate spheroids , whose equation of motion equations of motion have analytical solutions. More recent models are able to represent flexible fibers. The models rely heavily on continuum mechanics concepts and the numerical methods employed have some similarities to those employed in molecular dynamics , or in dynamics of multi body systems. The use of computers facilitates greatly the solution of fiber simulation problems. The complexity of the simulations arise from the system having a large number of degrees of freedom physics and chemistry degrees of freedom , and from the numerous possible interparticle interactions having place, such as friction , hydrodynamic interactions, and other kinds of interparticle forces such as colloidal forces that exert attractive or repulsive forces.

M5 fiber polyhydroquinone diimidazopyridine is a high strength synthetic fiber first developed by Dr. Doetze Sikkema ref name cummins http web.mit.edu course 3 3.91 www slides cunniff.pdf ref and his team at the Dutch chemical firm Akzo Nobel. Currently, it is being produced by the United States Magellan Systems International LLC. Preparation M5 fiber is prepared by a Dehydration reaction condensation polymerization between tetraaminopyridine and dihydroxyterephthalic acid using diphosphorus pentoxide as a dehydrating agent. The polymer mixture is then heated and extruded to form brightly blue polymer fibers. The fibers are then washed extensively with water and base in order to remove the phosphoric acid generated by the hydration of diphosphorus pentoxide from the polymer. In order to remove the water from the fiber structure and enable the intermolecular hydrogen bonds to be created and thus greatly increase the strength of the polymer, the fiber is heated and exposed to controlled stress. This aligns the fibers in the optimal configuration. Properties M5 is stronger than Aramid Kevlar , Twaron and UHMWPE Dyneema , Spectra . M5 is more fire resistant than meta Aramid. It is the most fire resistant organic fiber yet developed. It is less brittle than carbon fiber and will yield when stretched.

CTF3 Cuben Fiber is a product marketed and developed by the Cuben Fiber and Cubic Tech Corporations as a high performance non woven fabric for applications such as yacht sails, airship hulls, kites and many designs that require extremely strong rip resistance and light areal weight. History The name Cuben Fiber was coined by the press in reference to America C2 B3 America pronounced America Cubed , the winner of the 1992 America s Cup . During the 1992 Cup, that yacht reportedly used sails made from precursors to the currently available commercial product. In late 2007, the Cuben Fiber Corporation was acquired by North Sails. North Sails says they will continue to supply the materials to competitors on an as available basis. Cubic Tech Corporation has the exclusive rights to develop and sell Cuben Fiber type laminates for all non sailing applications. Production Cuben Fiber is a laminated fabric constructed from Ultra High Molecular Weight Polyethylene UHMWPE fiber monofilaments and polyester, PVF etc. films. Cuben fiber is sometimes confused with carbon fiber , one of the many fibers used as a reinforcement in some Cuben Fiber laminates. Cubic Tech Corporation s ultra high performance flexible laminates were re branded from Cuben Fiber to CTF3 TM in 2009. Cubic Tech Corp produces CTF3 with a wide variety of fibers such as Vectran, Carbon, Kevlar etc. Uses The material is used in yachting , performance sailing, windsurfing , inflatables, airship hulls, medical applications and increasingly in ultralight backpacking equipment, such as tents etc. Similar to sails made from traditional woven sail cloth, Cuben Fiber sails are constructed from panels that are bonded and sewn together, as opposed to 3DL sails that are laminated over a mold.
