Bad cable - Electrical characteristics prevents successful data transmission, Bad connector - Bent pins or incorrect pinouts prevent proper connection., Bad port - Confirmed by observing network connection LED and status indicators., Open - Broken strand of copper that prevents current from flowing through a circuit., Short - Two copper connectors touch each other resulting in current flowing through the defect rather than the electrical circuit., Splitting pairs in a cable - Four unused leads in unshielded twisted-pair cable used for connecting a second ethernet connection., dB loss - The signal power of a data transmission may be degraded to the point where the transmission is not correctly interpreted by a receiving device. The loss of power could result from exceeding the distance limitation of a copper or fiber cable., Transposed Tx/Rx Leads - Use of a straight through cable when a crossover cable should be used or vice versa., Cable placement - Electromagnetic interference of copper cables due arrangement., Attenuation - Digital transmission between devices is degraded because the cable exceeds the ethernet distance limitation, Crosstalk - Occurs when an analog connection creates an electromagnetic field around its conductors, iducing waveforms on a nearby analog connection.,
