    摘要: Analog transport of a wideband RF signal is effectively and efficiently provided using a coherent, narrowband optical carrier. The wideband RF signal is phase modulated onto the carrier at a first location. Non-coherent discrimination is applied to the modulated carrier at a second, different location to generate an amplitude modulated optical signal where the amplitude modulation represents the original wideband RF signal. A photo-detector is then used to regenerate a representation of the original wideband RF signal. The method and apparatus of the invention can be applied in systems dedicated to the analog RF transport or in wavelength division multiplexed systems which also provide transport for other analog or digital data.
