Abstract :
The dispersive mechanism which limits the transmission of microwave signals through step index singlemode (SISM) fibre at 1550 nm is outlined. Consideration of differential phase offsets in the optical field as it propagates through a dispersive fibre is shown to result in periodic conversion of an amplitude modulated (AM) signal into a frequency modulated (FM) signal which can not be recovered by direct detection. This effect is shown to be significant at frequencies in excess of 10 GHz after just a few tens of kilometres of SISM fibre
