Convergence of Future Passive Optical and Wireless Personal Area Networks for Triple Play Service Distribution Stuart Walker 1, Terry Quinlan 1, Mehmet Toycan 1, Manoj Thakur 1, Rouzbeh Razavi 1, Emilio Hugues-Salas 1 and Michael Parker 2 1 Dept. of Electronic Systems Engineering, University of Essex, Colchester, UK Tel: , Fax: , 2 Fujitsu Laboratories of Europe, Columbia House, Ipswich, IP5 3RE, U.K 28/04/ :41:441
28/04/ :41:442 All applications -- voice, data, image, video, multimedia -- conveyed on an all digital, packet-switched, Burst mode, broadband, low latency network or “platform” A “network of networks” platform that uses common, open, non-proprietary standards and protocols (e.g., the Internet Protocol -- IP) Extension of this platform using wireless technology to allow users to communicate anyplace, anytime, in any mode or combination of modes.

28/04/ :41:447 Burst Mode Receivers (BMRs) are a particular component situated in the OLT Function of the BMRs: Adaptation of the power intensity of each incoming burst Adaptation of the bit phase of each incoming burst Two main techniques for BMR: AC/DC coupling

Transmitter based on DFB laser array. MZ-modulator produces OFDM signal. 4-QAM OFDM signal. N=122 carriers with 528MHz bandwidth per band. 1xN power spilitter with an SOA switch in each arm. Acts as a high-speed optical switch to route the signal to the input ports of NxN AWG. SOA switches is also used as amplifiers to compensate for the loss of the splitter. The SOAs are activated according to the Latin routing characteristics of NxN AWG.
