Remotely Reconfigurable Remote Node for Hybrid Ring-Tree Passive Optical Networks

Free registration required

Executive Summary

Passive Optical Networks (PONs) are becoming consistent alternatives to offer access solutions in a Fiber-To-The-Home (FTTH) environment. Flexibility, scalability, resiliency, higher user density and bandwidth, robustness and extended reach are important features for the next generation PONs (NG-PONs), while maintaining simplicity to make the network economically practicable. Scalable Advanced Ring-based passive Dense Access Network Architecture (SARDANA) is an attempt to demonstrate how to exploit NG-PON in a cost effective and reliable way, allowing migration from the current deployed Ethernet PON (E-PON) and Gigabit PON (G-PON). SARDANA network is able to reach more than 1000 users spread over 100km, with symmetric 100Mbit/s per user.
