Typically, after crimping “hard wire” jumpers, users might plug them directly into devices, often performing only a basic continuity test. However, this approach does not adequately assess the performance of the jumper. A basic continuity tester merely indicates whether a connection exists, failing to consider the quality of the crimp or the effectiveness of the signal transmission.

In contrast, the production of factory-made gel-filled jumpers includes two rigorous rounds of testing. Initially, a continuity tester evaluates the quality of the connections. Only those that pass this preliminary assessment move on to the subsequent phase, which involves FLUKE testing to examine essential performance metrics such as insertion loss and return loss. Items that do not meet the stringent testing criteria are subject to rework, ensuring that only high-performing jumpers reach the market.
