How should the strength member of a loose-tube fiber-optic cable be handled?

The correct handling of the strength member in a loose-tube fiber-optic cable is essential for preserving the integrity of the cable during installation and any subsequent maintenance. Trimming back the strength member while ensuring it remains usable for clamping purposes allows for support and strain relief without compromising the overall structure of the cable.

By keeping the strength member intact and available for clamping, it helps maintain the cable's mechanical strength and protects the optical fibers from damage due to stress or tension. This approach allows for flexibility in installation and ensures the strength member can effectively contribute to the cable’s durability.

The other options suggest either removing the strength member completely or coiling it, which does not support the cable's integrity and can expose the fibers to risks. Tying off securely to the outer jacket without allowing for any movement also may not provide the necessary support during installation. Overall, maintaining the strength member in a way that it can still be utilized plays a critical role in ensuring the reliable performance of the fiber-optic cable.
