When can slack span design be used?

Slack span design is utilized in specific scenarios involving cable installation, particularly in outside plant environments. When the last section of the cable run is 100 feet or less, slack span design is applicable because it allows for easier management of cable slack and ensures adequate support and protection against environmental factors such as tension or vibration.

This design approach is advantageous because it aids in mitigating stress on the cable itself, particularly in regions where issues such as lateral movement, temperature changes, and physical forces could impact the integrity and longevity of the installation. In shorter spans, the risk of sagging or excessive tension is reduced, making it an ideal application for effective slack management.

In scenarios involving longer spans or larger numbers of cable pairs, different installation methodologies would typically be required to ensure optimal performance and reliability.
