Typically 8-10 metres in height. Supporting a fixed broadband cable above the highway that doesn't transmit or receive radio signals. Essentially the same as the common telegraph poles that carry telephone wires. These lines often share utility poles with higher-voltage electrical infrastructure, but their clearance requirements are distinct and primarily address public safety, preventing accidental contact, and maintaining service integrity. The regulations ensure that the lowest point of the sagging cable. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. The charter of the FOA was to promote professionalism in fiber optics through education, certification, and. Sag is generally limited to <2% of span length and maximum tension <30% of cable minimum breaking strength. All cables must be securely lashed to the messenger and/or cable (s).
