1. How do cat5, cat5e, cat6 and cat7 differ from one another?

Simply put, cat5 rates at 100MHz, cat5e rates at 100MHz, cat6 rates at 250MHz, cat6A rates at 500 MHz, and cat7 allegedly rates at 600MHz.

Nowadays, cat7 is not approved by the TIA, but is recognized by BICSI, NEMA, and the IEEE. Presently cat5e or cat6 are the most commonly used options in todays telecommunication systems. Cat6 cables are being created with separators that will deal with improved crosstalk and better 23 gauge conductor wires compared to the smaller Cat5e 24 gauge ones.

Cat5e comes with 100 ohm impedance, as well as electrical characteristics that support transmissions all the way up to 100 MHz. When it comes to performance, cat5 and cat5e differ in every aspect, such as attenuation, capacity, resistance, and frequency. The components of cat5e were especially made for high speed Ethernet. Although the components of cat5e work with gigabit Ethernet, they will perform below top standard if the distances are too long. So, if you use 1000 Mbps switches, cat6 cables would be better compared to cat5e cables.

The e in cat5e actually stands for enhanced and is totally backward compatible with modern equipment using cat5. Its improved electrical performance makes sure that the cables can support any applications which would need more bandwidth, like video or gigabit Ethernet.

Depends on use. Cat6 is usually the best for price/speed

@MrMaddog111 Yes, category 7 cable will work on a PS3.

[MrMaddog111]

Dose the cat7 caple work on a ps3

@DaRahamim ANSI/TIA-568-C.2 defines Category 5e from 1 MHz to 100 MHz. It also defines Category 6 to 250 MHz so the presenter here is indeed correct. You may see figures such as 350 MHz but they are marketing numbers that have no bearing on industry standards.

[DaRahamim]

I believe that Cat5E is actually rated at 350Mhz which makes it enhanced.

Cat6 is rated at 550Mhz.

Mr Server Rack. CAT5e has no bearing on indoor/outdoor cable. It is simply a standard. There are plenty of outdoor "Rated" Category cable.

@sdfan00 Cat7 is the best cable you can get for a copper network. Fibre is better if you can obtain the correct equipment though.

[sdfan00]

cool so is a cat 7 the best you can get or is it the best and please tell me the exact type of cable i need which category and all the other stuff
