The optical fiber filling paste is used for filling the material in the optical fiber loose tube in the optical cable. It has two aspects of protective action to the optical cable: firstly, prevent that moisture or the moisture in the air from corroding the optic fibre, secondly play the backing effect to the optical cable, cushion the optic fibre and receive the influence of mechanical force such as vibration, impact, bending, be one of the decisive factor that the optical cable performance can be stable for a long time. It is mainly composed of three major parts of base oil, thickening agent and antioxidant. The compatibility adaptability and the flow resistance of the currently used power optical fiber filling ointment are insufficient.
