The Traceable Patch Cord product line is an effective solution for eliminating interconnect errors in dense interconnect environments. From the back of the equipment to the front of dense frames, or cross room interconnect, the Traceable Patch Cord product utilizes a positive light indication to identify the other side of the patch. The product concept focuses on adding

functionality into a simple patch cord to be able to trace the other end of a connection. This is particularly targeted for high density environments where cable congestion can create a challenge in tracing patch cords, and finding the other end of a cable, across a bay or for inter-bay connections. | FEATURES · LED indicator at both ends of jumper · Simple LED tool to apply power to one end of jumper to easily identify the far end of a jumper in connected area · Assemblies are available in singlemode Bend Insensitive Fiber (BIF) and multimode OM1 and OM3 fiber types · All assemblies meet

TIA/EIA and IEC intermateability standards. RoHS compliant · Available in a wide variety of lengths.
