Abstract:
PROBLEM TO BE SOLVED: To provide a switchable optical fiber device for fiber transmission system and a component for the same. SOLUTION: This optical fiber device is composed of a 1st fiber 12 for transmitting the light of a certain wavelength and a loop-shaped fiber 18 for transmitting the light of a certain wavelength and the loop-shaped fiber is connected through an optical switch 20 of the 1st fiber between on terminal and the other terminal of the 1st fiber. When the switch is turned on, an optical path to be communicated from the 1st fiber to the loop-shaped fiber and to be in communication along the 1st fiber again is selectively supplied, and when the switch is turned off, an optical fiber to be communicated along the 1st fiber but not in communication to the loop-shaped fiber is selectively supplied, so that switchable operating characteristics can be provided.
Abstract:
A fiber optic device for use in fiber optic transmission systems and components thereof includes a pass-through fiber and one or more lengths of circulating fiber connected to the pass-through fiber by respective optical switches for selectively routing an optical signal through the circulating fiber lengths as it propagatesalong the pass-through fiber. The circulating fiber lengths are either dispersion compensating fibers or fibers doped with a substance that will amplify or absorbthe optical signal in the respective presence or absence of a pump signal. The invention thus allows various amounts of dispersion or gain (absorption) to be selectively switched into or out of use depending upon requirements at the time.For example, an amplifying component could serve as a pre- or power- or in-line amplifier device depending on the lesser or greater amount of gain fiber electedby switching. The device can be interconnected with the transmission system or components thereof via splicing to of the ends of the pass-through fiber or via optical switches connected to the ends of the pass through fiber.
Abstract:
Un dispositivo de fibra optica para su uso en un sistema de transmision de fibra optica y componentes de los mismos incluye una fibra de paso continuo y una o más longitudes de fibras circulantes conectadas a la fibra de paso continuo por los respectivos conmutadores opticos para enviar selectivamente una señaloptica a través de las longitudes circulantes de fibra conforme se propaga a lo largo de la fibra de paso continuo. Las longitudes de fibra circulante son o bien fibras compensadoras de dispersion o fibras impurificadas con una substancia que amplifica o absorbe la señal optica en la respectiva presencia o ausencia de una señal de bombeo. La invencion permite por lo tanto que se conecten selectivamente varias cantidades de dispersion o ganancia (absorcion) para su uso o desuso dependiendo de las necesidades al momento. Por ejemplo, un componente amplificador que podría servir como un dispositivo amplificador previo o de potencia o en línea dependiendo de la menor o mayor cantidad de fibra de ganancia elegida por medio de conectar; se puede interconectar el dispositivo con el sistema de transmision o los componentes del mismo por medio de empalmar a los extremos de la fibra de paso continuo o por medio de los conmutadores opticos conectados a los extremos de la fibra de paso continuo.
