Bending radius of the optical cable after laying
Always keep the fiber optic cable bend radius at least 20 times the cable diameter during installation and 10 times after installation to prevent damage and signal loss. Ignoring these rules leads to improper installation, signal loss, and costly cable damage. During installation under tension, maintain a minimum bend radius of 20 times the cable's outer diameter, while post-installation requires a minimum long-term bend radius of 10 times the cable diameter.
