Optical amplifiers for wavelength division multiplexed systems |
摘要 |
An optical amplifier for a wavelength multiplexed transmission system has a set of optically amplifying fibres (26a, 26b) each provided with an associated spectrally selective Bragg reflector (27a, 27b). The amplifying fibres are optically coupled with a coupler (23) such that an optical signal having different spectral components launched into an input (21a) of the coupler is emitted from an output (21b) of the coupler after the different components have propagated through different ones of the amplifying fibres each after reflection in its associated reflector. <IMAGE> |
