...ratios • Within a CATx cable of a certain length, the individual pairs might have individual different lengths, caused by higher or lower twist ratios. • There are two common cable standards: • One with a 2 + 2 structure (two pairs of approximately...

...cabling is good, solid cable for 100-Mbps LANs. The Category 5 standard has been around since 1991, so it’s well established. You’ll find existing Category 5 installations everywhere. What can Category 5 cable do, and what can’t it do? • If you sti...

...of the most important cable measurements is Near-End Crosstalk (NEXT). It’s signal interference from one pair that adversely affects another pair on the same end. Crosstalk occurs between adjacent wire pairs (“pair-to-pair NEXT”). In addition, all...

...Fibre optic cable not only gives you immunity to interference and greater signal security, but it’s also constructed to insulate the fibre’s core from the stress associated with use in harsh environments. • Fibre cable contains a coating...
