Optical fibre cable with ultra-high density of more than 3 fibres/mm/sup 2/

Proposed is an ultra-high-density 100-fibre cable that uses 0.25 mm diameter mono-coated optical fibres with a low bending loss. This cable has great advantages in terms of cable weight and diameter and will be easy to install in a small space in underground ducts and/or on residential and business premises. The optical fibre with the optimum low bending loss is selected experimentally to obtain optical fibre cable with the maximum fibre density. A 100-fibre cable with a fibre density of more than 3 fibres/mm² and a cable diameter of 6.3 mm was obtained
