Abstract

A system for extending communication equipment using flat coaxial cables, the system occupying a minimum installation space and providing equipment extensions and interface changes in a flexible manner. The system comprises a rack carrying a base shelf and at least one extension shelf. The base shelf has a plurality of base PWB assemblies inserted therein, and the extension shelf accommodates a plurality of extension PWB assemblies. One end of a flat coaxial cable bundle is attached removably to the front of each base PWB assembly. With its extra length portion left in a first tray on the base shelf, the flat coaxial cable bundle passes through the tray from front to back to enter a second tray from its back on the extension shelf. With another extra length portion left in the second tray, the flat coaxial cable bundle leaves the front end of the second tray to connect detachably to the front of each extension PWB assembly.
