Unbalanced Digital Crosstalk in Balanced, Twisted Pair, Inside Wiring Cable,
BELL TELEPHONE LABS INC NORCROSS GA
Pagination or Media Count:
A model is derived that accurately predicts pulse crosstalk between two unbalanced circuits in a multipair cable. If pair integrity is maintained and single point grounding is observed, coupling is capacitive and increases directly with length. If unused conductors are allowed to float, coupling capacitance increases strongly, but predictably. Based on this model, twisted pair inside wiring cables are capable of transmitting digital signals over longer distances and at greater rates than those recommended in industry standards. Author
