Proper data cable installation requires the following:
Plan the cable routes and cable length needs.
See QSFP+ Data Cable Overview and 10GBASE-T Data Cable Overview.
Ensure that cable route turns are larger than 85 mm (3.4 inches) radius for optical cables.
Find alternative routes for turns that are tighter.
Secure the cable to hard points and bundle it with soft, hook-and-loop fasteners.
Mediate the slack between securing points to maintain minimal cable tension and proper support.
Label the ends of cables to identify their routes.
Rest the cable connectors on a stable surface when they are not connected.
