A key issue to reach a highly scalable Passive Optical Network (PON) with veryhigh splitting ratio is the high multiplexing level required to handle all individualsignals (individual data flows) that travel along shared fibres. The available fibrebandwidth and current high-speed electronics allow high splitting ratios togetherwith high bandwidth per user assignments. An objective in a next generation PON(ngPON) is to perform the multiplexing with limited complexity. The possiblemultiplexing techniques in the key architectures are discussed in this chapter.
