FIELD: physics. ^ SUBSTANCE: telecommunication cable has at least one optical fibre coated with a dense buffer layer, having an inner diameter which is essentially equal to the outer diameter of said optical fibre Said dense buffer layer is made from polymer material having ultimate elongation equal to or less than 100% and ultimate tensile strength equal to or less than 10 MPa. ^ EFFECT: effective protection of the fibre during installation work and during use, easy cleaning without any cleaning tools by applying low pressure using fingers and moderate tearaway force along the axis of fibre, wherein cleaning can be carried out in a single operation. ^ 31 cl, 5 dwg |
