Long length hermetically coated fiber
Optical Fiber Communication, 1990A piece of carbon coated fiber more than 70 km long was obtained from a large VAD preform that showed fatigue parameter n > 200 and no loss increase due to hydrogen permeation after exposure to a hydrogen environment.

Birefringence distribution along fiber length
Optical Fiber Communications, OFC., 2005We demonstrate the Birefringent Optical Circuit Synthesis (BOGS) capable of estimating modal coupling and phase-shift distributions along a fiber length. By measuring the Stokes parameters dependence on optical frequency, we can derive the unitary matrix elements as z-polynomials to synthesize the birefringent lattice optical circuit.

Variability of Fiber-Length Parameters
Textile Research Journal, 1972The variability of fiber-length parameters obtained from the Baer Sorter and the Digital Fibrograph has been estimated. It has been found that the two methods have the same order of variability. The need for considering Type II errors, while detecting small changes in fibei lengths, has been brought out.

Short length fiber Faraday rotator
Optics Communications, 1991Abstract We report the fabrication of an all-fiber Faraday rotator relying on the enhanced field produced by alternating pairs of permanent NdFe magnets. An active rotation of 45° has been obtained from 40 cm of a standard single-mode fiber with less than 1.0 dB of throughput losses. Possible improvements of the device are also discussed.

Beat-length measurement of birefringent optical fibers
Optics Letters, 1987We present a novel technique for the measurement of the beat length of birefringent single-mode fibers based on differential attenuation induced by a metal. The proposed technique is particularly suited for the measurement of local birefringence in polished-fiber semiplates. The technique should also find application in the characterization of polished

Polarization mode dispersion in short fiber lengths
Journal of the Optical Society of America A, 2006We perform Monte Carlo simulations of the statistical properties of the differential group delay for fiber lengths less than and of the order of the birefringence correlation length. We find that the manner in which quantities related to the polarization mode dispersion evolve along the fiber depends significantly on the model assumed for the form of ...

Journal of Reinforced Plastics and Composites, 2012
In this study, short carbon fiber-reinforced polypropylene composites with three different initial carbon fiber lengths were prepared by using extrusion compounding and injection molding techniques. The physical and morphological properties of the prepared short carbon fiber-reinforced composites were investigated by means of tensile test ...

Estimation of Fiber Orientation and Length in Fiber Assemblies
Textile Research Journal, 1978General formulas are derived for the estimation of fiber orientation and distribution in fiber assemblies whose constituent fibers are arbitrarily crimped. It is found that the density function of orientation can be estimated by solving an integral equation which relates it to the average numbers of fiber cross sections formed on the unit areas of ...

Muscle fiber conduction velocity changes with length
Muscle & Nerve, 1993AbstractWhile recording activity from individual muscle fibers by single fiber EMG (SFEMG), stimulated either through their axons or directly, the length of the recorded muscle fiber was changed—stretched or made shorter—by manipulating the recording needle or by passive joint movements.

Stability of polycrystalline AgHal-fiber characteristics with fiber length
SPIE Proceedings, 2003In development of various devices on the basis of IR fibers is very important to know such their optical characteristics as spectral transmission, numerical aperture, far-field divergency with various conditions of fiber launching and, in particular, stability of these characteristics with fiber length.
