Cat5E Cable

Category 5 cable or CAT5, as it’s referred to more often, is a twisted pair high signal integrity cable type. Such cables come in shielded or unshielded versions.

However, now CAT5 cable has been superseded by the brand new Category 5e cable specification structured cabling which is utilized primarily for computer networks, as used in Ethernet usage.

CAT5e is moreover used in order to carry many other signals. These include different signals such as ATM Asynchronous Transfer Mode, token ring–defined as a local area network technology in a local area network protocol, and also basic voice services.

There are twisted pairs held in a single cable jacket specifically within all CAT5e cable. The reason for this is that it preserves the high signal-to-noise ratio to prevent crosstalk.

CAT5e cable is mostly used in 100 Mbit/s networks. Typically this kind of cable features three different twists for each inch of twisted pair 24 gauge copper wires inside each cable.

The test methods and the characteristics of the CAT5e cable are defined in ANSI TIA/EIA-568-B.2-2001. The newer cable has much stricter performance specifications than the CAT5 that it replaces, however it still does not provide longer cable distances in the instance of Ethernet networks.

Those particular cables still must adhere to 328 feet (100m) in length that allows for 5m of end patch cable that needs to be at each end. However, the specifications for CAT5e add some very special specifications to far end crosstalk.

Cross talk signals that are transmitted on a CAT5e cable are defined as some sort of undesired effect happening to yet another circuit or channel than the one being used in that particular cable.

Ordinarily cross talk is often caused by undesired conductive coupling, inductive, or capacitive information from one circuit or channel to yet another. This is why the CAT5e cable systems use the twisted pairs when making analog connections.

Also, the signals may well be converted to digital form, thus rendering the signals to become much less susceptible to crosstalk. The simple description of crosstalk is when one signal affects another nearby signal.

CAT5e cables come in two forms, the stranded and the solid conductor form. The stranded form is considered to be much more flexible so that it can be used around corners and such.

The solid form is much cheaper and sometimes has been used unscrupulously instead of the better stranded form. This results in extremely unreliable connections as the solid conductor form cable may well break when someone tries to force it around a corner, for example.
