Abstract :
Taking advantage of the low path loss in a local optical network, a coherent subcarrier multiplexed star distribution system with a local oscillator (LO) generated at the centre and shared by all the subscribers is introduced. The potential advantages of this single LO system include: simple receiver structure, system cost effectiveness, enhanced system reliability, minimised laser phase noise and IF drift, as well as easy system expansion.
