Bidirectional WDM-Radio over Fiber System with Sub Carrier Multiplexing Using a Reflective SOA and Cyclic AWGs
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2011, Vol 2, Issue 8
Abstract
A bidirectional SCM-WDM RoF network using a reflective semiconductor optical amplifier (RSOA) and cyclic arrayed waveguide gratings (AWGs) was proposed and demonstrated. The purposed RoF network utilizes Sub Carrier Multiplexed (SCM) signals for down-link and an on-off keying (OOK) signals re-modulated for up-link. In this paper, A 50 km range colorless WDM-ROF was demonstrated for both 1 Gbit/s downstream and upstream signals. The BER performance of our scheme shows that our scheme is a practical solution to meet the data rate and cost-efficient of the optical links simultaneously in tomorrow’s ROF access networks.
