Abstract
Abstract Single-mode W-Fibres with a special threshold layer surrounding their inner cladding can be designed to have zeroes of their dispersion coefficient at three different wavelengths, and as a consequence typically less than 1 ps/(nm km) dispersion over a wavelength range of nearly 0.4. µs (Figure 1).

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
17 words
Single-mode W-Fibre, characterised in that there is a threshold layer of raised index surrounding their inner cladding.
Claim 2
Dependent Claim
17 words
Single-mode W-Fibre, characterised in that there is a threshold layer of raised index surrounding their inner cladding.
Claim 3
Dependent Claim
65 words
Fibre as in claim 1, characterised in that the ratio of the inner and of the outer diameter of these threshold layer and the ratio of the diameter of these threshold layer and of the diameter of the core of these fibre is between 1,4 and 1,8 and that the refraction-index is about 0,05 to 0,15 % greater than the refraction-index of the outer cladding.
