It has a layered structure in which a protective layer 6 and a shape retaining layer 4 are sequentially provided around the outer periphery of the optical fiber 2. In this embodiment, the protective layer 3 includes a primary coating layer δ1 made of silicone rubber or the like around the outer periphery of the optical fiber 2, and a buffer layer 6b made of a silicone rubber lining having better elasticity than the primary coating layer 5m. A secondary coating layer 6C made of nylon or the like is sequentially provided to form a nine-layer structure. The protective layer 3 may include only the primary coating layer 61, or may include only the primary coating layer 3& and the buffer layer 3b. The shape-retaining layer 4 is made of glass fiber, boria Z-type fiber, or the like. It is made of a fiber-reinforced thermosetting resin in which the fibers are coated and impregnated with thermosetting m@4b such as epoxy resin or polyester resin, which is bent into a spiral shape and hardened to maintain its shape. is being carried out. Along with this, the formation of such a shape-retaining layer 4 and the spiral shape The bending process can be carried out as follows: Covering the outer periphery of the protective layer 6 with the fibers 4a.
For example, it can be braided, unidirectional spiral winding, bidirectional spiral winding, etc. In the case of spiral winding, the fibers 4a can be wound around the outer periphery of the protective layer 6, for example, in the form of a string, a woven fabric tape, or the like. The fibers 4a can also be made into a tape and covered vertically. A thermosetting resin 4b is coated and impregnated on this layer of fibers 4&, and the resin 4b is semi-cured, thereby making the shape-retaining layer 4 a flexible and non-stick prepreg layer.

ある。When tension is applied to such an optical transmission line 1, the pitch of the helix is extended, but in this case, no tension is applied to the optical fiber 2 until the helix is completely extended, and the optical fiber 2 is not likely to break. Prevented. When the tension is removed or disappears, the optical transmission line 1 returns to its original state due to the spring force.
Since the optical transmission line 1 having such a structure is provided with the shape-retaining layer 4 made of fiber-reinforced thermosetting resin, it has a much better shape-retaining ability than a layer of thermoplastic resin.
The helical shape is stable and has a strong advantage against creep.
