Hey just a quick question....Whats the difference between CAT5 and CAT5e
i learned this is CISCO networking....but i dont pay attention lol...

thx

well.. i can try to help..

cat5: its network cable for under 100mb/s max disance for safty to run ..100 feet.
cat5e: tightly round ..and can be used up to gigabit networks. also is good for all round stuff.. since its almost the same price. runs over 500 feet with out any loss

do note.. cat5 cat5e and cat6 (cat6 is for high speed networks) all that cat whatever stuff is just a rateing that the manufactor give them ..and are ment to run at that speed.

they are only good if the nic you are useing is as good. And yes. you can get a tester to get cerafied cat*

cat 5e is spun tighter than cat5, and is good for 1000mbit as wizard james said.

obvoiusly if you got a nice kink in your 500ft cable, it won't go 500ft :D

cat5e: tightly round


cat 5e is spun tighter than cat5

..same thing.. mine was a bad choice of word tho lol.

also like at my nearby store ..they sell cat5e and cat6 in the 500 and 1000 foot boxs.. ever need to go through 2 1000 foot boxs in one day? talk about alot of wireing.. long store and noone needs to know.. lets just say 200 million dollers of servers is alot of wireing that needs done ..what better then get a 15 year old kind like me to do it!

Aside from how the wires propagate physically, the cat5e standard is more specific about various values. Both standards specify ratings for - 100mhz, 100 ohm, and 100 meter. Additionally, cat5e specifies capacitance, frequency, attenuation, and Near-End-Cross-Talk, which then dictates suddle differences in how the wire is wound and terminated.

Cat5 conductor size for the wire is 26 awg, cat5e is 24 awg.

Within these standards there are T568A and T568B - the only difference AFAIK is that the orange and green pairs of wire are switched. T568B is the vast majority of what is used, though T568A can be used in a T568B network without any problems. And of course, the government requires T568A because they love to do things different.

Unfortunately for us leachers, IEEE standards requires a subscription to access their information so its hard for me to decipher what exactly is fully accurate as there are many places I found with plain wrong information.

ok now i recall :p
Ok so i got a 500meter reel of it, a crimp and some RJ45's
Now to go from the router to a switch, i make the cables in a straighthrough format correct?

Ive gone through 10 1000 foot boxs on a site before. When you wire up 20-30 story hotels you go through cable quick

yes, you only need a crossover if you dont have a hub switch or router. Nic to nic crossover, and for uplinking switchs and hubs

just a correction to information provided by wizard james:

the maximum length for any utp(unshielded twisted pair(category 5, 5e, 6, 7) is 100m.

ahh i see.. i didnt know for sure on that. ..thats still 300 feet.. anything farther ..got optical
