The DSX- 4D modular family is designed to be compatible with CommScope DSX-3 front cross- connect frames. Physical chassis alignment, as well as compatibility of the cross-connect jumper retainer clip, allow this DSX product to be placed in existing CommScope DSX-3 frames (note: modules are not interchangeable between ADC and CommScope chassis). Larger capacity jumper rings and a removable designation label plate enhance the administration and management of the DSX system. The one-piece design of ADCs dual cross-connect jumper retainer clip gives added strength and retention to hold jumpers in place. Dual crossconnect jumpers constructed from twin shielded miniature coaxial cable with a 24-gauge center conductor combine high perf o rmance with robust physical strength in a compact package.
