Fiber optic cables are designed in such a way that the optical fiber has, related to the cable, excess length. The overlength protects the fiber in the event of bending stress or tension on the cable. In central tube cables, the EFL is typically zero to a fraction of 1%. Water friction and the high cooling rate of the plastic compound creates problems with waste and post shrinkage, limiting line speed and the quality of the final product. Excess fiber length in a loose tube is a parameter. NDC Technologies, a leading global provider of precision measurement and control solutions, sees a growing trend among loose tube fiber and fiber ribbon cable manufacturers to accurately and efficiently control the excess fiber length (EFL) of products to ensure the fiber-to-jacket ratio meets.

[pdf] On average, the installation or initial cost for fiber optic cable can range from hundreds to thousands of dollars per mile for aerial installation and $5,000 to $20,000 per mile for underground installation. Ins.
[pdf] Aerial Suspension: A type of fiber optic cable known as "aerial suspension" uses high-tension wires stretched between the two ends of the transmission line. These wires are used to facilitate cable installation and to keep the cable lines elevated. (The cable can also be non-metallic). The jelly prevents the passage of water in longitudinal direction while it at the same time protects the fibres. 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.
