Route Planning for Optical fiber cable laying
It is recommended that a survey of the cable route should be conducted. Manholes and ducts should be inspected to determine the optimum splice point locations and duct assignments. Potential problems
What should be noted when laying optical cables in ducts
Optical fiber cables can be installed in ducts using pulling or blowing methods, following strict guidelines for tension, bend radius, innerduct fill, and safety to ensure cable integrity and performance.Cable Handling and SpecificationsMaximum Pulling Tension: Each cable type has a specified maximum pulling tension, typically around 600 lbF (2,700 N) for stranded loose tube and ribbon cables, but always refer to the cable datasheet for exact limits .Minimum Bend Radius: During installation, the cable must not be bent below its minimum bend radius. A common guideline is 15 times the cable diameter for working bend radius, and twice that for pull wheels or rollers .Crush and Strain Limits: Avoid exceeding the cable's maximum crush load and fiber strain limits (usually
