Installation of Optical Fiber Cable

WithHiroshi Murata

This chapter discusses the installation methods of optical fiber cables in ducts and aerial applications. Optical fiber cables are commonly used for communication and data transmission worldwide. The use of manual assistance or a cable sender in the intermediate manholes is a simple technique that is unique to optical fiber cable laying into ducts. The standard length of one optical fiber cable length is 1 to 2 km, compared with 150 to 500 m with copper conductor cable because optical fiber cables are light and small in mechanical dimensions and because total loss of fiber splices must be minimized by increasing the cable length. The cable was pulled using cable senders at three locations in manholes. Cables are normally laid out by hand or cable sender. When using a winch, tension should be monitored with a tension meter, and the work should be performed accordingly.
