Abstract

PURPOSE:To prevent optical fibers from the increment of transmission loss by adhering optical fiber cores coated with thermosetting resin reinforced by glass fiber which constitute a nonmetallic optical cable with fillers at the inside of a mold member to clamp the optical fiber cores without using a mechanical clamp. CONSTITUTION:A clamping part 10 of a nonmetallic optical cable incorporated with fiber cores coated with thermosetting resin (FRP) reinforced by glass fiber consists of a cable constituting member 14 composed of fiber cores coated with FRP and high tension fiber flux or FRP tension members and a plastic sheath 16. The clamping part 10 is fitted to the sheath of a clamping end of a nonmetallic optical cable 12 and composed of a sleeve-like mold member 20 with which the exposed part of the cable constituting member 14 is coated, fillers 20 with which the inside of the mold member 18 is filled so as to bury the cable constituting member 14 and a protective sleeve 22 expanded along the sheath 16 of the nonmetallic optical cable.

保つことができない。Recently, FRP elliptical fiber cores with FRP (glass fiber-reinforced thermosetting paulownia resin) coated around the optical fibers have been developed.
A non-metallic optical cable was developed in which a number of f:yr fibers were assembled and a non-metallic sheath was sheathed thereon. In this optical cable, the protective sheath for the optical fiber is made of FRP, so it is strong against tension and is suitable for aerial installation. As a means of securing such a non-metallic optical cable to a steel tower, etc., it is generally considered to use a clamp fitting, but if such an optical cable is firmly tightened with a clamp fitting, the F'RP coating of the core wire may be damaged. Furthermore, if the cable is simply tightened with a clamp fitting, there is a risk that the cable will be damaged by one clamp per clamp when the cable vibrates due to wind, making it impossible to maintain reliability over a long period of time. .

As shown in the figure, it is preferable for this protective sleeve to have pleated protrusions 22a on the outer surface of the protective sleeve.If this is done, the creepage distance will be increased and the insulation resistance value will be reduced due to icing and salt damage. Since the protective sleeve 22 and the mold member 18 engage with each other at the protrusions 22a, the strength of the connection is increased. Further, the protection sleeve 22 may be in contact with the sheath 16 or may not be bonded to the sheath 16.

Also, when filling and curing the filler, a certain amount of heat and pressure is applied to the optical fiber core wire, but since the core wire has class a F)tP, it can withstand this for a light amount of time, which increases the transmission loss of the optical fiber. Nor. 1. Since the mold member and cable sheath are covered with a protective sheath, there is no risk of damage to the retaining part due to vibration, and a stable retaining part can be formed over a long period of time.
