Common Hidden Dangers in Fiber Optic Cables in Ducts
In large buildings or data centers, fiber often shares trays or conduits with AC mains. While these cables are engineered for durability (with some rated to last 25+ years), they are not invulnerable. Corning Optical Communications cable specification sheets are available which list the maximum tensile load for various cable types. The maximum pulling tension for stranded loose tube cable and ribbon cable is 600 lbF (2,700 Newtons). Whether it is completely congested ducts, rat's nests of existing cables or poorly protected fiber connections, here are the top seven issues that we've come across when helping carry out implementations across the world. • The National Electrical Safety Code (NESC), published by the Institute of Electrical and Electronics Engineers (IEEE), specifies safe practices for installing, operating, and maintaining electric supply and communications lines and equipment.
