Abstract
An optical fibre cable includes a generally cylindrical elongate central support structure with helical grooves formed around its periphery. The grooves (2) are partially filled with the compound (3) which is viscous at cable operation temperature. Said support structure (1) is then cooled to reversibly harden said compound (3). Optical fibres (4) are then layed in the grooves over the compound in its hard state. Lastly the grooves are topped up with viscous compound.
