Proper data cable installation requires the following:
Plan the cable routes and cable length needs.
Identify problematic cable route bends, minimizing the length of continuous vertical runs to no more than 2 meters (7 feet), and specify hardware to support cable routing.
Carry the entire cable to the points of connection and unroll the cable from the first connection point to the second
Keep the coil closed and pause to enable the cable to relax as it is unrolled and moved through turns.
Ensure that cable route turns are larger than 85 mm (3.4 inches) radius for optical cables and 127 mm (5 inches) radius for copper cables.
Find alternative routes for turns that are tighter.
Secure the cable to hard points and bundle it with soft, hook-and-loop fasteners.
See Data Cable Bundling.
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.
