OPTIONS AND TRENDS FOR PON TUNABLE OPTICAL TRANSCEIVERS
Michael J. Wale1; 1Oclaro Technology Ltd., United Kingdom.
 Tunable laser-based solutions are attractive for future access systems based on wavelength division multiplexing, in view of their high performance and flexibility. This paper assesses the present state of the art and current trends.

VCSEL-BASED DWDM PON WITH 4 BIT/S/HZ SPECTRAL EFFICIENCY USING CARRIERLESS AMPLITUDE PHASE MODULATION
Roberto Rodes1, Marcin Wieckowski1, Tien-Thang Pham1, Jesper Bevensee Jensen1, Idelfonso Tafur Monroy1; 1DTU Fotonik, Technical University of Denmark, Denmark.
 We experimental demonstrate successful performance of VCSEL-based WDM link supporting advanced 16-level carrierless amplitude/phase modulation up to 1.25 Gbps, over 26 km SSMF with spectral efficiency of 4 bit/s/Hz for application in high capacity PONs.

 A network-embedded self-tuning cavity is proved in WDM-PON transmission over 32 channels, with two-ONU simultaneous operation and downstream signal. Performance at 1.25 Gb/s are experimentally analyzed after 25 km and 50 km SSMF.

RAYLEIGH SCATTERING ROBUST ACCESS NETWORK BY Λ-SHIFTING THROUGH EXTRACTION OF SUPPRESSED RZ CLOCK HARMONIC

 Wavelength shifting based on the all-optical clock recovery of a RZ-downstream with suppressed clock harmonic is presented, avoiding in-band Rayleigh backscattering for choosing this particular harmonic as upstream carrier, even for a low OSRR <10dB.
