摘要: An upgrade at the physical layer regarding unbundling and dynamic bandwidth provisioning of a wavelength division multiplexed access network is presented. The capability reflective modulator to act as photodetector exploited allows tandem configuration be used optical unit (ONU) for flexible switching detection modulation branch. Consequently, mechanism service operator selection partitioning up twice nominal data rate provided. scheme experimentally evaluated different kinds modulators shows, together with full-duplex transmission 10 Gb/s, additional operation modes, featuring unidirectional downstream upstream burst-mode 20 Gb/s ONUs based on combination semiconductor amplifier electro-absorption modulator.
