...in different, adjacent cables. • Factors that affect Alien Crosstalk • The amount of ANEXT depends on a number of factors, including the proximity of adjacent cables and connectors, the cable length, cable twist density, and EMI. Patch panels and c...
...Optic Mode-Conditioning Cables. • Launching a single-mode laser into the centre of a multimode fibre can confuse the receiver at the other end if multiple signals are generated. Differential Mode Delay (DMD) effects create these multiple signals, wh...
...6a • Category 6 and 6a Cables • Category 6 • The next level in the cabling hierarchy is Category 6 (CAT6) (ANSI/TIA/EIA-568-B.2-1), which was ratified by the TIA/EIA in June 2002. CAT6 provides higher performance than CAT5e and features more string...
...of Category 5 cables are already specifying PS-NEXT tests. Cables that meet PS-NEXT requirements should deliver superior performance and will be able to support future higher-speed transmission schemes. • Pair-to-pair NEXT measures signal ...
Attenuators • Attenuators • Attenuators filter strength of fibre optic signal • Attenuators are used with single-mode fibre optic devices and cable to filter the strength of the fibre optic signal. Depending on the type of attenuator attached ...
...to gel-filled sleeves. • Cable jacket • This is the outer layer of any cable. Most fibre optic cables have an orange jacket, although some types can have black or yellow jackets. • Learn more: • Loose-tube vs. tight-buffered fibre optic cable. •  
Shielded Ethernet Cables • Shielded Ethernet Cables • STP and S/STP • Two basic types of shielded cables are offered by Black Box and the Industry.The first group are cables with an overall shield know generically as STP. The second are constr...
...and CAT5e or CAT6 cables (delay skew) • If you connect CAT5e or CAT6 cable to a CAT5 extender, the result is blurry images on your monitor. The effect is known as delay skew, but do you know what causes it? • Different lengths • Believe it or ...
