Project Summary

The goal of the proposed project is to develop cost-effective techniques for the integration of multiple groups of services in a Fibre-to-the-Home (FTTH) network which is based on multimode optical fibre.

Multimode optical fibre provides a cost-reducing alternative for the commonly used single-mode fibre. Multimode fibre is easier to install than single-mode fibre with its tiny core: due to its larger core diameter, the coupling of light from a light source into the fibre and the (fixed or demountable) splicing of fibres together is easier. In particular in the access network, this may yield a considerable reduction of installation costs. The bandwidth-times-length product of single-mode fibre is significantly higher than that of multimode fibre. As in the access network the fibre links are less than 10 km, however, the bandwidth of presently commercially available silica multimode fibres is quite sufficient.

In this project it is therefore proposed to develop system concepts for the integration of various independent groups of services in a single FTTH infrastructure, using multimode optical fibre. These concepts will encompass a variety of optical multiplexing methods. The methods already known for single-mode fibre networks are mostly not applicable in multimode fibre networks, and new ways have to be explored how to fit these into multimode networks. In addition, other new multiplexing methods exploiting the multimode nature of the network in particular will be investigated Both silica multimode fibre and the upcoming polymer optical multimode fibre will be considered.
