摘要：The present invention relates to an apparatus and method of producing coatedoptical fiber in which polarization mode dispersion is sufficiently reduced by providing asufficient amount of twist thereto. An upstream twisting inhibiting roller (11), a twist non-inhibiting roller (12), a twist provider (13) and a downstream twist inhibiting roller (14) areprovided in this order along the path line of a coated optical fiber (1). The twist provider(13) provides the twist to the coated optical fiber (1). The upstream twist inhibiting roller(11) and the downstream twist inhibiting roller (14) respectively inhibit a rotation of thecoated optical fiber (1) around the axis of the coated optical fiber (1). The twist non-inhibiting roller (12) functions so as to adjust the path line length of the coated opticalfiber (1) located between the upstream twist inhibiting roller (11) and the twist provider(13), and does not inhibit the rotation of the coated optical fiber (1) around the axis of thecoated optical fiber (1).
