At what height is an OSP zone defined as 75' or higher?

In the context of outside plant design, a zone defined as 75' or higher is referred to as a Zone Cone. This classification is important in relation to the vertical reach of aerial infrastructure. The concept of a Zone Cone helps to address clearance requirements for overhead utilities and the safety of installations. The designation corresponds to structures or installations that are situated at significant heights, which can have implications for equipment logistics, maintenance, and potential interference with other services.

Understanding the concept of different zones, including the Zone Cone for higher elevations, is essential for ensuring compliance with design standards and safety protocols in outside plant projects. It reflects the consideration of various physical factors, such as terrain, existing infrastructure, and adherence to regulatory requirements, all of which are critical in the planning and execution of outside plant designs.
