How many twisted pairs are in a Cat 5 cable? | |||
---|---|---|---|
Solution:
4 pairs as per T568A Standard - pin for pin (not crossover) - per Marc for 1 meter cable
Standard Pairs:
#1 & 2 (pair 3)
#3 & 6 (pair 2)
#4 & 5 (pair 1)
#7 & 8 (pair 4)
Standard connections use pairs #3 and #2 - a crossover cable swaps pairs #2 and #3
