摘要： Disclosed is an improved, single-mode optical fiber possessing a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses.The coating system features (i) a softer primary coating with excellent low-temperature characteristics to protect against microbending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness. The secondary coating provides improved ribbon characteristics for structures that are robust, yet easily entered (i.e., separated and stripped).The optional dual coating is specifically balanced for superior heat stripping in fiber ribbons, with virtually no residue left behind on the glass. This facilitates fast splicing and terminations. The improved coating system provides optical fibers that offer significant advantages for deployment in most, if not all, fiber-to-the-premises (FTTx) systems.
摘要翻译：公开了一种改进的具有新型涂层系统的单模光纤。当与弯曲不敏感的玻璃纤维组合时，根据本发明的新型涂层系统产生具有异常低损耗的光纤。涂层系统的特征是（i）具有优异的低温特性的较软的初级涂层，以防止任何环境和最强的物理情况下的微弯曲，以及（ii）具有增强的颜色强度和鲜明度的着色的二次涂层。二次涂层为坚固但容易进入（即，分离和剥离）的结构提供改进的带状特征。可选的双涂层是特别平衡的，用于在纤维带中实现优异的热剥离，玻璃上几乎没有留下残留物。这有助于快速接合和终止。改进的涂层系统提供光纤，为大多数（如果不是全部）光纤到户（FTTx）系统中的部署提供显着的优点。

摘要： The present invention embraces an amplifying optical fiber having a central core adapted to convey and amplify an optical signal and a cladding that surrounds the central core to confine the optical signal conveyed in the central core. The central core is formed of a core matrix in which nanoparticles are present. The nanoparticles themselves include a nanoparticle matrix and rare-earth-dopant elements. The core matrix may also include one or more additional dopants (i.e., in addition to nanoparticles). The amplifying optical fiber possesses a small numerical aperture and is suitable for use in high-pump-power applications without a degraded gain shape.

摘要： An electric current generation device includes a rotatable rotor including a magnet assembly establishing a magnetic field proximate the rotor. A stator includes at least one set of coils disposed with respect to the rotor so that rotation of the rotor moves the magnetic field with respect to the coils of the coil set to generate electric current flow in the coil set. The coil set includes an impedance component in communication with the electric current flow to limit the rate of increase of electric current flow generated by the coil set as the rotational speed of the rotor increases. The winding direction of at least one coil with respect to the magnetic field may be opposite the winding direction of the other coils with respect to the magnetic field. Two coil sets may be provided wherein the coils of a first coil set are wound so that the output of the first coil set is out of phase with respect of the output of a second coil set. A rectifier mechanism in operative communication with the first coil set and the second coil set rectifies and combines the output of the first coil set and the output of the second coil set.

The central core has a radius r1 and a positive refractive index difference Δn1 with the optical cladding. The intermediate cladding has a radius r2 and a refractive index difference Δn2 with the optical cladding, wherein Δn2 is less than Δn1. The depressed trench has a radius r3 and a negative index difference Δn3 with the optical cladding. At a wavelength of 1310 nanometers, the optical fiber has a mode field diameter (MFD) between 8.6 microns and 9.5 microns and, at a wavelength of 1550 nanometers, the optical fiber has bending losses less than about 0.25×10−3 dB/turn for a radius of curvature of 15 millimeters. At a wavelength of 1260 nanometers, attenuation of the LP11 mode to 19.3 dB is achieved over less than 90 meters of fiber.
