Abstract: A patch cord, a management system and a management method thereof are provided. The patch cord (10) comprises a connection line portion (11), a first connector (21) arranged at a first end of the connection line portion (11), a second connector (22) arranged at a second end of the connection line portion (11), a first communication unit (31) arranged at near the first connector (21) including a first identifier and a second communication unit (32) arranged near the second connector (22) including a second identifier, wherein the first and second identifiers contain unique identify information for identifying the first connector and the second connector, respectively, and wherein the first identifier is different from the second identifier. The management system and the management method can differentiate connectors at the both ends of the patch cord by self-identification.

Abstract: An upgradeable distribution framework, cable connector and cabling management system is described. The distribution framework has a plurality of ports adapted to be connected by cable connectors and indicator elements arranged on the distribution framework wherein corresponding to at least a portion of the ports. A plurality of first communication units are detachably secured to the cable connectors and such that the first communication units are positioned outside the ports when the cable connectors are inserted into the ports. The distribution framework further includes a plurality of second communication units that correspond to at least a portion of the ports. The second communication units and the corresponding first communication units are configured to communicate with each other in a non-contact manner. A control modules is configured to control and read and write communications between at least a portion of the first communication units and the second communication units.
