Requirements for outdoor non-metallic optical cable laying
163 describes criteria for the installation of optical fibre cables defined in Recommendation ITU-T L. 110 in remote areas with lack of usual infrastructure for installation including the procedures of cable-route planning, cable selection, cable-installation. There are three common laying methods for outdoor optical cables, namely: underground pipeline laying (that is, laying optical cables in underground pipelines), direct underground laying and overhead laying (that is, laying from utility poles to utility poles in the air. Depending on engineering. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. The cable should be of low weight, small volume and high flexibility. The mechanical design and construction of each unit shall be inherentl ings are required to show the outline of fiber optic. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed.

Measures for pulling and stretching electrical wires connected to distribution boxes
Use spool rollers (Figure 4) that allow spools to rotate in place and release wire smoothly without twisting. There are four key operating components used in an overhead distribution stringing job: the tensioner, pulling line (bull line), stringing blocks, and the puller. These key pieces should work together, and if any one of these components is deficient, either in design or performance, it directly. Conduit installation, wire pulling, and termination are interdependent tasks that must be carried out in a specific sequence to ensure the safety and functionality of the electrical system. Pulling devices include pulling ropes, swivels, pulling eyes, and pulling grips (crimp-on and basket type). The conductors of the cable are generally the only members that can bear the pulling forces. Conductor stringing is the process of installing overhead power lines or conductors onto transmission towers or distribution poles.
