Abstract :
This paper proposes an upgrade scenario for xDSL networks to provide broadband access for extended link lengths while demonstrating network grooming by means of more than one subscriber using a single network connection concurrently. This is achieved by applying direct spread code division multiple access (DS-CDMA) in a fiber-to-the-cabinet (FTTC) topology by means of a field programmable gate array (FPGA), used to demonstrate simultaneous user transmission and system-on-chip (SoC) network element generation. Experimental results have displayed efficiency in ADSL link rates of 66% and 41% for back-to-back and 12 km-reach fiber links respectively.
