Abstract
The present invention relates to an optical fiber and an optical cable which can be used for a long term even under environments in which an oil content migrates into them, and the optical fiber has a glass fiber extending along a predetermined axis, and a coating. The coating is composed of a plurality of layers each of which is comprised of an ultraviolet curable resin or a thermosetting resin, and swelling rates of the respective coating layers are set so that they increase from an outer peripheral surface of the glass fiber to an outer peripheral surface of the cable jacket.
