The DCX System from Belden is an end-to-end fiber infrastructure system that provides high fiber termination density in a compact form with 3,840 terminations per DCX cabinet, or 1,280 terminated fibers per square foot. This system is designed to maximize signal integrity through bend radius control for incoming and outgoing cables. It also features optical distribution front-access cabinets that are configurable and scalable by assembling side by side and/or back-to-back, cabinet components including additional cable entry brackets and patch cord telescopic spools, optical distribution frame housings available in left-to-right and right-to-left configurations with a front-access design, and rack-mount patch panel housings available in 1U, 2U and 4U configurations that are compatible with all DCX cassettes and adapter frames. The adapter frames and cassettes maximize return on investment by migrating networking technologies in the same housing such as the assembly of two, four, or six cassettes per housing tray.
