Implementation a Laser Beam Adjustment of Overhead Fiber Optic Cable Sheaves in Railway Tracks

摘要

The modernization of safety and telecommunication installations in the railway track Blagoevgrad-Kulata has a subject the delivery, installation and training equipment for telecommunications, signaling and automatic level crossing devices. Using a Pulling Rope Method for of All-Dielectric Self-Supporting fiber optical cable a laser beam adjustment of overhead fiber optic cable sheaves is proposed for application over railway tracks. The appropriate adjustment tools are shown and efficiency evaluations of the advantages of implementation are pointed out. As a result the necessary requirements and precaution for installation are defined.
