OPTICAL FIBER |
摘要 |
An optical fiber having at least a structure for effectively suppressing the increase of microbend loss, preferable to dispersion-flattened optical fiber, dispersion-compensated optical fiber, and so forth, and adapted to compensate the single mode in the wavelength band used. Particularly, the optical fiber has a diameter of 140 mu m or more and consequently has a high rigidity. Since the increase of the microbend loss is effectively suppressed and the fiber diameter is below 200 mu m, the probability of rupture due to bending strain does not practically bring up any problem. The optical fiber has a larger mode field diameter, so that the optical energy density per unit cross section is small and nonlinear optical phenomena are effectively suppressed.
