89 describes the general requirements and a design guide for suspension wires, telecommunication poles and guy-lines that support aerial cables for optical access networks. This Recommendation also describes loads applied to the infrastructures. Aerial installation is generally much less costly than underground construction also. Unlike buried cable, they excel in rural or suburban areas where trenching is impractical. Key advantages include: Cost. Recommendation ITU-T L. Aerial infrastructure. SERVICE DROP STANDARDS COVER SHEET / TOC 60. CHECK UTILITY POLE OWNER REQUIREMENTS FOR MINIMUM SEPARATION BETWEEN DRILLED HOLES. *SEE RUS DRAWING NUMBERS 241 & 214 (APPENDIX A, SHEETS 1&2) FOR ADDITIONAL. Many people are confused about the hanging of aerial optical cables. In fact, there are two methods for aerial optical cables laying: one is "fixed-pulley traction method", including "manual traction method" and "mechanical traction method"; the other is "cable tray moving and releasing method".
