The Simple Answer:
CAT-5e is rated to 350M
CAT-6 and CAT6e are rated to 550M or 1000M depending on your source
CAT-7 is supposedly rated to 700M or presumably 1000M
Today there is no approved CAT-6 or CAT-7. While some folks are selling products they call Level 6 or 7, there aren't even specs for them, making Cat5e Plenum Cable the best available option. Cat6 Plenum Cable cable is being made with 23 gauge conductor wire as opposed to the slightly smaller 24 gauges for CAT-5e and also has a separator to handle crosstalk better.
Both CAT-5 and CAT-5e have 100-ohm impedance and electrical characteristics supporting transmissions up to 100 MHz. The differences between CAT-5 and CAT-5e show in all aspects of performance: capacitance, frequency, resistance, attenuation, and NEXT. CAT-5e components were designed with high-speed gigabit Ethernet in mind. While CAT-5 components may function to some degree in a gigabit Ethernet, they perform below standard during high-data transfer scenarios. CAT5e cables work with ATM and gigabit speed products. Simply, if you are using a 100Mbps switch, get CAT-5e cable instead of CAT-5.
CAT-5e is formally called ANSI/TIA/EIA 568A-5 or simply Cat-5e (the e stands for 'enhanced'). CAT-5e is completely backward compatible with current CAT-5 equipment. The enhanced electrical performance of CAT-5e ensures that the cable will support applications that require additional bandwidths, such as Gigabit Ethernet or analog video.
CAT5e, Category5 Cables enhanced, cables can support 1GB/s at 100 meters whereas the CAT6/ Category6 Cables, cable is an enhanced version which can handle pressures up to 10GB/s at only 55 meters. Thus CAT6 supports higher bandwidths in comparison to CAT5e.
CAT5e and CAT6 cables show variations in frequencies as well. CAT5e Cable has a frequency of 350MHZ whereas the category 6 patch cable has a higher frequency which is 550MHZ.
CAT5e and CAT6 cables have the ability to counter electromagnetic influx from all sources. The radiations are emitted by matter all around us. Charged species do emit higher doses of radiations such as the electric equipment, circuits and so on. Electrons are lost and gained by various atoms and it’s an ongoing phenomenon. The gain of an electron by an atom means a release of radiations and these radiations can penetrate into the nearby computing devices too.
One can expect more radiations in an area of congested cable and wire systems. The networks of computers are connected by cables. So one can expect more ‘cross-talk’ that is disruptions as a result of EMI’s
The CAT5e and CAT6 cables have been provided with the unique ability to counter this crosstalk so that the computing operations aren’t affected.
Twisting and shielding allow enhanced performance. CAT5e and CAT6 cables are coated with a protective layer added to go along with the twisting of the conducting wires. Each pair of the conducting wires is twisted alternatively to deter the EMIs.
The flow of data, signals and the mobilization of computing resources becomes streamlined and efficient.
Both the series of Ethernet cables can handle the pressures of crosstalk’s and foreign intrusions but definitely, CAT6 is an advanced version. CAT6 can support higher bandwidths and boost the overall process of signal routing.
CAT5e was an updated version of CAT5 cables, where ‘e’ stands for enhanced. But CAT6 cables have replaced both the older versions.
Computing operations need to be handled with utmost care for quality performance. Maintenance of computing resources is also mandatory. The selection of a suitable patch and Ethernet cables can help relieve computers of all undue pressures.
