Evolvable, sustainable low power optical network architectures
David. B. Payne1,2; 1CSCT, CTVR/Trinity College Dublin, Ireland; 2School of engineering, Swansea University, United Kingdom.
Optical communications technology offers an opportunity for radical restructuring future telecommunications networks. The major challenges for future networks with fibre to the premises (FTTP) is; economic viability, resource sustainability, the ability to evolve and adapt to new technologies with out large scale uplifts, particularly of the physical layer infrastructure, and also be able to accommodate a wide range of operating and business models. This Tutorial will examine these issues and possible network architectural solutions that offer potential economic viability, substantial reductions in resource usage, particularly power consumption, and the ability to evolve as new technologies emerge in the future.

Power and Energy Consumption in Broadband Fixed Access Network Migration
Christoph Lange1, Dirk Kosiankowski1, Andreas Gladisch1; 1Laboratories, Deutsche Telekom AG, Germany.
The impact of broadband access network migration on the power and energy consumption is studied by establishing an analytic migration model. The results show that power-aware strategies are necessary for efficient broadband access network migration.

Experimental Evaluation of Cyclic Sleep with Adaptable Sleep Period Length for PON
Martina Fiammengo1, Alexander Lindström1, Paolo Monti2, Lena Wosinska2, Björn Skubic1; 1Ericsson Research, Sweden; 2Royal Institute of Technology KTH/ICT, Sweden.
An experimental evaluation of cyclic sleep for PON is presented where different control algorithms for adaptable sleep length period are compared.

Dynamic Sleep-Mode ONU with Self-Sustained Fast-Lock CDR for Power Saving in 10G-EPON Systems
Naoki Suzuki1, Kenichi Kobiki1, Eitetsu Igawa1, Junichi Nakagawa1; 1Information Technology R&D Center, Mitsubishi Electric Corporation, Japan.
We present a novel 10G-EPON power-saving ONU employing a self-sustained fast-lock CDR IC. With its self-generated quasi-synchronized signal based CDR control, a fast wake-up of ONU within 497ns supporting heavy duty DBA cycles was fully achieved.
