This invention allows the multi ended Telecom and data test cords to operate at the highest level of transmissions provided over the copper pair.
If you have a test cord that has three to four plug ends on it, they are generally connected inside a Y junction, since the telephone system was developed using up to two copper pairs, and only one copper pair was used to monitor the pair at a time.
The test set known as the butt set or handheld test was originally designed to access or bridge into one pair at a time. The amount of leads coming from that buttset was/is two. This has always been the means of bridging onto the telephone line.
With the invention of the multi ended test cords, the only way to connect to this single pair test set was to combine the additional test end pair internally in a Y junction combining four pairs to one pair, four tip wire to one tip from the test set and four ring wires connected to one single ring wire coming from the test set. These additional, unused pairs, left hanging in the air, and act as mini antennas- causing a condition referred to as “bridge taps”.
Generally, reducing the cost in all industries is a common goal; in regards to that the concept of this invention is to not only isolate the pair, but also reduce the cost by not having an electrical switch.
The Isolated Pairs are packaged with two test ends. The technician has everything they need at their fingertips for testing, saving time and money.
