Embodiment Construction
[0038] exist figure 1 A single-mode optical fiber 6 is schematically represented in , which is obtained after shrinking the preform and drawing it into an optical fiber. The single-mode optical fiber 6 can be regarded as a light-conducting core 4 which is surrounded by an inner cladding part 3 which in turn is surrounded by a jacket part 1 . A liner is suitable, for example, as jacket part. The refractive index of the core 4 is greater than that of the inner cladding portion 3 and the jacket portion 1, where the latter two are practically equal. It should be noted that in Figure 1-6 The same designations used in are consistent with each other.
[0039] exist figure 2 A specific embodiment of a single-mode optical fiber 6 is schematically shown in FIG. A cushioning layer 2 is surrounded, and the cushioning layer 2 is finally surrounded by a jacket part 1 . This single-mode optical fiber 6 is manufactured according to the method of the present invention, using a silica l...
