QDF Two-wire and Four-wire Test/Patch Cords

A variety of QDF test/patch cords is available for use with QDF-E termination magazines. They provide access to circuits for testing, monitoring, and temporary or permanent patching. The cords can bridge or tap into circuits (without circuit interruption) for passive monitoring. They can also be configured to provide break access (i.e., circuit interruption) to the line pair (A1, B1) or equipment pair (A, B) for testing or patching.

• the "make-before-break" capability prevents critical data loss when monitoring circuits
• plug-end markings identify correct polarity when plugged into a QDF-E access slot
• available in a variety of configurations to accommodate all testing and patching applications
