Abstract: 

The present deliverable reports on the lab trial results of the optical access technologies developed in MUSE Phase II. This research mainly aimed at solutions for node consolidation, but also included cost improvements for future optical access networks.

Various approaches for node consolidation have been evaluated in laboratory trials.

A prototype of XL-PON system has been demonstrated and tested in various laboratories. XL-PON key performance figures are: 10 Gbit/s data rate from the network to the subscriber (downstream) and 2.5 Gbit/s upstream, 512 as the maximum number of optical terminations and 100 km as the link range for the optical transmission

The demonstration of basic functions and tests of transmission and applications were successful.

XL-PON holds the concept of simple broadband access and dramatic reduction of active electrical components.

The network can be thus planned in a highly flexible way with a maximum number of components that are simple and low-maintenance, passive and energy-saving.

Alternative techniques for BMR were analysed . These techniques include AC and DC coupling, Edge Detection with a differentiator and a discriminator configuration; and the DSPK technique.

Considering the entire CWDM wavelength grid from 1270 to 1610nm a maximum reach of about 10km has been observed for a worst-case, but practically relevant crosstalk scenario. This result is bit rate independent (1.25 Gbps…10Gbps) and has been achieved without FEC.

We have demonstrated a resilient CWDM-based network running the newly developed Fast Access Ring Protection Protocol

(FARPP).

The operability of the OFM system to provide FWA services over long fibre links has been studied with experiments and theoretical work for distances up to 75km, and has demonstrated to be a cost low, robust and suitable RoF system for the implementation in the XL-PON architecture.
