Cable Carriers
Cable Carries help in guiding the cable as the chassis is pulled out or retracted back into the rack. One end of the cable carrier is attached to the back of the chassis while the other end of the cable carrier is attached to the fixed end [non-moving] end of the slide rail within the rack. The cable(s) are then attached to the cable carrier which insures that they move freely as the chassis is moved in and out of the rack.
Be sure to specify the cable insulation if it's important to the finished design. A military spec chassis may preclude the use of PVC because of the amount of smoke PVC produces when it catches fire. Changes from PVC to Teflon insulation could add cost to the system at the last minute.
If the individual wires need a particular color code, or if a wire bundle need to be a certain wire color code than call that out in the chassis specification. Some MIL Specs require Cable Bundle jacket color coding; individual cable bundle jackets shall be color coded for identification in accordance with EIA/TIA-598. EIA-598 will also apply to Ribbon fiber color coding and fiber Binders. In many cases the cable jacket will be Black.

Do the cables require a particular Back Shell, will the back shell and cable bend radius fit within the chassis.

Optical fiber cables may be
run in cableways with electric power and signal cables. However, optical fiber
cables should not be installed in cableways with armored cables unless no feasible
alternative routing exists. If optical fiber cables must be installed in the same
cableways as armored cables, additional precautions must be taken during
installation to prevent mechanical damage. |
 Cable Retractor |
Design hint; The plastic cable-way shown is plastic. However; many retractor arms only move in one angle and are produced only in metal. The metal arms only have one pivot point. Normally the cables are just tie-wraped to the end of the metal arm which is just used to secure the cables, as the chassis is moved the arm bends at one point to allow the cables to move with the chassis.
