Abstract : A vast range of applications for nonmetallic optical fiber cables making good use of their noninductance to electricity, such as computer links, robot control, induction-free observation and control in power plants, and temporary communications for emergency telephones, field telegraphs, and so on, can be expected. However, conventional types of nonmetallic optical fiber cables have many problems for practical use such as high elongation, low tensile strength, inadequate waterproof properties, and poor temperature stability of transmision loss. Therefore, development of cables solving these problems has been desired. The authors have developed nonmetallic optical fiber cables having three-layer-coated optical fibers separately housed within helical-grooves of a spacer formed around an FRP strength member by direct polyethylene extrusion through a specially shaped rotary die.
