Abstract :
The results of the analysis of the COCONUT (“COst-effective COhereNt Ultra-dense-WDM-PON for λ-to-the-user access”) project architectures with respect to their associated cost, power consumption and migration scenarios are presented. COCONUT develops udWDM access with simplified coherent technology to allow for node consolidation, increased number of homes passed, and higher split ratios when compared to standardised technologies. COCONUT can operate in a very narrow spectral band due to the 6.25 - 12.5 GHz wavelength channel spacing and provides increased per user capacity when compared to currently deployed solutions. COCONUT technology shows 80% cost reduction when compared to a conventional coherent receiver. Also in terms of power consumption at 10G, the adopted transceiver solutions compare well to TWDM PON solution, achieving less than 2 W/Gb/s.
