...money. • Computer cables can only be too short, but never too long. The same applies to networking cables. Sometimes it is just the last meter that is missing, but in many cases some kilometres are missing. A standard 10/100 or 10/100/1000 Cop...
...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...
...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...
...within a loose-tube cable. It can be a headache-inducing task if you don’t have the right tools. If you bend the cable or buffer tubes past their recommended bend radius, or if you allow them to kink, you’ll end up with substandard cable connect...
...Bending a fibre cable • One of the most important considerations when installing fibre optic cable is maintaining the minimum bend radius. Bending a fibre cable excessively may cause the optical signal to refract and escape through the cladd...
...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...
