Abstract

PURPOSE: To protect optical fibers and stabilize their transmission characteristics by enclosing the optical fibers with repellent plastic tapes and providing an extrusion covering layer on the outside thereof.
CONSTITUTION: One or plural optical fibers 1 are loosely enclosed by a repellent plastic tape 2. An extrusion covering layer 3 in close contact with the outside part of the tape 2 is then provided. Such constitution enables the optical fibers to be protected and the transmission characteristics of the optical fibers to be stabilized. The optical fibers 1 are manufactured in this way. Namely, the optical fiber 1 is let off from a bobbin 10 and is placed with a tape 2 longitudinally. While the tape is being formed to cylindrical form by a molder 5, it encloses the optical fiber 1. The fiber then passes through a guide of an ordinary cylindrical shape in the cross head 7 of an extruder 6, whereby an extrusion covering layer 3 is formed. Further, if necessary, the outside covering layer is extruded while reinforcing fibers 4 are being supplied to the inside or outside circumference of the tape to form a reinforcing fiber layer 4, whereby the structural body is manufactured.
