...used with these cables. • OM3 and 4 are manufactured without the center defect. As networks migrated to higher speeds, VCSELS became more commonly used rather than LEDs, which have a maximum modulation rate of 622 Mbps. Because of that, LEDs...

...and receive pairs are crossed between Connector A to Connector B on either end of the cable. There are two standards for the pairing of Crossover cables, one for the 568-A  & 568-B and one for USOC. • Learn more: • UTP Cable and colour drift •  

...image quality over long cables. • You can then manually adjust the video equalisation (fine-tuning the total system response from graphics card output to your eye). • This can’t be attained with automatic equalisation based on cable length measureme...

...Shield • BLACK BOX® STP cables feature the same core and jacket as the widely used Unshielded Twisted Pair (UTP) cables. And they contain a drain wire and a foil shield that covers all four pairs. The plugs on STP cable are also shielded. • Foiled T...

Single-Mode Fibre Optic Cable. • Single-Mode Fibre Optic Cable • Multimode fibre cable has multiple modes of propogation - that is, several wavelengths of light are normally used in the fibre core. In contrast, single-mode fibre cable has only...

...video or RGB coax cables, which often can’t be easily pulled through tight conduits and can be more difficult to terminate (for more on the limitations of simply extending video cabling, see below). • A bonus: In most buildings, copper cabling...

...Common ground • The cables share many characteristics. Although 50-micron fibre cable features a smaller core (the light-carrying portion of the fibre), both 50- and 62.5-micron cable use the same cladding diameter of 125 microns. Because they h...

...Loose-tube cables • Loose-tube cables, the older of the two cable types, are specifically designed for harsh outdoor environments. They protect the fibre core, cladding, and coating by enclosing everything within semi-rigid protective s...

...attach to optical cables, which are constructed with a PVC jacket and a plastic core. The cables transfer information accurately over short distances via digital light signals with low loss and no distortion. • Digital optical cable less expen...

...use a lower sreen resolution, or use a video skew compensator. • A video skew compensator removes colour drift by delaying some colour signals to compensate for differences in wire pairs. • Learn more: • Light injector for copper patch cables •
