Group wiring patching system and method for wire pair identification

摘要

A group wiring patching device which has built-in light emitting device and filtering device coupled with wire pair receptacle thereof. When a testing voltage is applied to the circuit of the light emitting device, the light emitting device will emit light for assisting wire pair identification. The filtering device can minimize or even eliminate loop back shorting resulted by the circuit of the connected light emitting when communication signals or low voltage signals being applied thereto. Therefore, the group wiring patching device of the present invention will be able to perform ordinary signal transmitting functions without the need to remove the light emitting device after the wire pair identification process is done.
