  • Publication number: 20240248001
    Abstract: An object of the present invention is to provide an optical fiber testing method and an optical fiber winding device capable of appropriately reproducing the same lateral pressure and minute bending state in a test of an optical fiber as those in an optical cable. In the optical fiber testing method according to the present invention, an optical fiber 51-2 of the second layer wound around a bobbin 12 is used as an object to be tested. Lateral pressure to the optical fiber 51-2 of the second layer is applied by an optical fiber 51-3 of the third layer. The lateral pressure is adjusted by a tension when the optical fiber 51-3 of the third layer is wound around the bobbin. In other words, since the lateral pressure is applied to the optical fiber to be tested from another optical fiber, the same lateral pressure and minute bending state as those in the optical cable can be reproduced.
