Abstract
Se trata de una unidad amplificadora optica (100:100) para amplificar senales opticas en un sistema de transmision optica que presenta una banda delongitud de onda de amplificacion con un límite de longitud de onda inferior mayor que 1570 nm y que incluye una entrada (101) para la entrada de senalesopticas, una salida (102) para la salida de senales opticas. y un amplificador optico (104) intercalado entre la entrada (101) y la salida (102) paraamplificar las senales opticas. El amplificador optico (104) incluye una fibra de amplificacion (108) co-impurificada con erbio e iterbio, al menos una fuentede bombeo (109,110) para generar radiacion de bombeo y al menos un acoplador optico (111,112) que acopla opticamente las fuentes de bombeo (109,110) a lafibra de amplificacion (108). La unidad de amplificacion optica presenta una ganancia de energía de al menos 31 dB cuando las senales opticas presenten unapotencia de entrada de al menos -10,5 dBm y longitudes de onda dentro de la banda delongitud de onda de amplificacion.It is an optical amplifier unit (100: 100) for amplifying optical signals in an optical transmission system that has an amplitude wavelength band with a lower wavelength limit greater than 1570 nm and that includes an input (101 ) for the input of signal signals, an output (102) for the output of optical signals. and an optical amplifier (104) interspersed between the input (101) and the output (102) to amplify the optical signals. The optical amplifier (104) includes an amplification fiber (108) co-impurified with erbium and iterbium, at least one pump source (109,110) to generate pump radiation and at least one optical coupler (111,112) that optically couples the sources of pumping (109,110) to the amplification fiber (108). The optical amplification unit has an energy gain of at least 31 dB when the optical signals have an input power of at least -10.5 dBm and wavelengths within the amplitude wavelength band.
