Namibia ADSS optical cable pre-stretched
Cables must be designed for the worst-case combinations of temperature, ice load, and wind. An installed cable must not sag so low that it can be damaged by traffic under the line. On long spans where utilities already experience caused by sustained high wind, dampers may need to be installed on ADSS cable also. The cable specifications should allow for operation at the lowest expected temperature.

Does the reinforcing core of indoor optical cable need to be grounded
Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. This Applications Engineering Note (AE Note) discusses conventional bonding and grounding practices for conductive fiber optic cable and hardware installations within the scope of the National Electrical Code (NEC). That is, drive a rod into the dirt. Grounding on the load side doesn't serve any electrical purpose, but it does waste. Since an optical fiber cable is non-conductive and there is no electric flowing, there are several advantages over a twisted copper cable in deploying: The non-conductive (dielectric) characteristics of fiber impacts how a designer lays out cabling pathways. When designing with fiber, you can. Part I of Art. 770 of the National Electrical Code (NEC) provides the general requirements for optical fiber cables.
