Abstract :
We investigate the impact of ASE on the phase noise in LMDS incorporating optically amplified transport links. ASE noise is found to dominate and significantly increase the phase noise of the received RF signal after transmission over >70 km of optical fibre. This effect is also demonstrated in a transmission experiment with 4 MHz 16 QAM data at 28 GHz
