When testing communication cables, what should the resistance read approximately per 100 feet of length?

The correct reading for resistance in communication cables is approximately 1 ohm per 100 feet of length. This low resistance indicates good conductivity and ensures that the signals transmitted through the cables are not significantly attenuated. In diving systems, reliable communication is crucial for safety and effective operation, which is why maintaining low resistance in cabling is a priority during testing. A higher resistance reading may suggest poor connections, corrosion, or damage in the cable, potentially compromising the integrity of the communication system. Therefore, aiming for around 1 ohm per 100 feet serves as a standard benchmark for ensuring optimal performance in communication cables used in diving operations.
