1. An optical ring network structure comprising:
- two or more network elements, and a single optical fibre connection between each pair of neighbouring network elements for carrying an optical signal, wherein the ring network structure is arranged in a manner such that, in use, band allocation utilising multiplexing on each single fibre connection is chosen in a manner such that groups of wavelengths for bi-directional data transfer and for bi-directional redundant data transfer for protection respectively are provided on each single fibre connection.

18. A method of distributing data on a optical ring network structure, the optical ring network structure comprising two or more network elements, the method comprising the step of;
-
distributing a bi-directional multiplexed optical signal on single optical fibre connections between each pair of neighbouring network elements, wherein band allocation utilising multiplexing on each single fibre connection is performed in a manner such that groups of wavelengths for bi-directional data transfer and for bi-directional redundant data transfer for protection respectively are provided on each single fibre connection.
