Evolution scenario towards WDM-PON
Journal of Optical Communications and Networking, 2009In this paper we present and critically discuss different wavelength division multiplexing passive optical network (WDM-PON) architectures compatible with pre-existing gigabit PON (GPON) infrastructures. The concurrent use of the trunk fiber permits a hitless evolution from an existing time division multiplexing optical access network to a pointto ...

Wavelength-agnostic WDM-PON system
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016Next-generation WDM-PON solutions for metro and access systems will take advantage of remotely controlled wavelength-tunable ONUs to keep system costs as low as possible. For such a purpose, each ONU signal can be labeled by a pilot tone modulated onto the optical data stream.

Spectrum-sliced bidirectional WDM PON
Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2002We demonstrate a bidirectional wavelength-division-multiplexed (WDM) passive optical network (PON) based on spectrum-sliced technique. This network transmits fifteen 500 Mbps downstream and fifteen 155 Mbps upstream channels over single strand of conventional single-mode fiber.

Recent Developments in WDM-PON Technology
2006 International Conference on Transparent Optical Networks, 2006Considerable research is being conducted to exploit the potential of novel WDM-PONs exhibiting individual, data and protocol agnostic virtual point-to-point (p2p) links for each ONU. The research focuses on the deployment of uniform building blocks throughout the entire access network and on upgrading the channel data rate efficiently towards 10 Gb/s ...
