[pdf] Wireless-PONs with Extended Wavelength Band Overlay
Milos Milosavljevic, Pandelis Kourtessis, John M. Senior
Optical Networks Group, Science and Technology Research Institute (STRI), University of Hertfordshire, Hatfield, AL10 9AB, UK
Abstract: An advanced architectural platform based on wireless-enabled PON topologies is described. Network modelling of WiMAX channel transmission, based on FDM, over a multiwavelength,
splitter-based PON has demonstrated EVMs below -30dB and error-free multipath transmission.

Abstract: Proposition and demonstration of a novel wavelength-divisionmultiplexing orthogonal-frequency-division-multiplexing passive-opticalnetwork (WDM-OFDM-PON) architecture with centralized lightwave sources and polarization shift keying (PolSK) multicast overlay. The 10Gb/s 16QAM-OFDM point to point (P2P) signal, 2.5-Gb/s multicast PolSK signal and 2.5-Gb/s on-off keying (OOK) upstream signal are experimentally demonstrated. After transmission over 25km standard single mode fiber (SMF), 1.5dB crosstalk between the downstream signals is eliminated by employing a low pass electrical filter at the PolSK receiver. The power penalty of the upstream OOK signal at BER of 10−9 is less than 0.1dB.

Brendon J. C. Schmidt, Arthur J. Lowery and Liang B. Du
Department of Electrical & Computer Systems Engineering, Monash University, Clayton, 3800, Australia
Abstract: We experimentally demonstrate a novel colorless transmitter for direct-detection optical OFDM that requires lower sample-rate DACs than previous designs, without RF mixers. We transmit 24-Gbit/s over 800-km SSMF using two 10 GS/s DACs.

Abstract: OFDM allows flexible adjustment of transmission data rate according to channel properties. We propose to use OFDM transponders and calculate the cost at which OFDM networks result in lower CAPEX compared to traditional networks.
