Modular high density communications chassis

A modular high density communications chassis, comprising:

• a chassis configured for receiving communications equipment and cable management, defined by a first panel, a second panel, and two opposing side panels, forming an access mounting opening, comprising:
• a chassis module track system, longitudinal to the two opposing side panels on the first and second panels;
• and
• a pull-out cable management system assembled to the chassis at the access mounting opening, longitudinally moveable therewith, configured for receiving communications equipment and cable management, defined by a first cable management panel, a second cable management panel, and two opposing cable management side panels, forming a first mounting opening and a second mounting opening, comprising:
• at least a handle, configured to longitudinally move the pull-out cable management system;
• a cable management module track system longitudinal to the two opposing cable management side panels on the first and second cable management panels;
• an operational position;
• and
• a cable management position;
• and
• at least two or more slidable carrier modules, each comprising module rails on opposing sides thereof, respectively,
• wherein one of the at least two or more slidable carrier modules is slidably mounted to the chassis via the chassis module track system, and an other of the at least two or more slidable carrier modules is slidably mounted to the pull-out cable management system via the cable management module track system, whereby the at least two or more slidable carrier modules are neighboring, and when the pull-out cable management system is assembled to the chassis in the operational position, an end of one of the at least two or more slidable carrier modules mounted to the chassis extends outward from the access mounting opening and an end of the other of the at least two or more slidable carrier modules mounted to the pull-out cable management system lies flush with a plane of the access mounting opening, and when the pull-out cable management system is assembled to the chassis in the cable management position, the end of one of the at least two or more slidable carrier modules mounted to the chassis remains extending outward from the access mounting opening and the end of the other of the at least two or more slidable carrier modules mounted to the pull-out cable management system extends further outward from the access mounting opening past the end of one of the at least two or more slidable carrier modules mounted to the chassis.
