Rj45

[preet]

Hi evryone.
I was making some research on how to crimp an RJ45 jack. the tutorials were fine and clear. so l learned, the basics thatis, the color code(straight throu), and to start the cable should be cut at a precise length, group the different wires, push it i the jack in order respecting the color code 1 to 8 and apply the crimper. i was on the verge buying the jack and cable to try my first crimping. but to my great surprise wen i looked inside the jack i was a bit confused. there was 4 holes align up and 4 holes align down.

can anyone tell me how should i insert the wires and which hole is the first of the eight, should start counting up or down?

thx

Hold the connector with the clip facing the floor.

Is this what you have and meen by 4 up and 4 down?

If so just follow variables color scheme going up then down then up then down starting at the one closest to the end.

Note: using the jacks like this with the sleeves are way better since you can push the wire up to the twists then cut it as well it holds the wires for you while putting it inside the jack (only can have half inch of untwisted wire), I found it easier to do it with clip facing up and backwards starting with brown since the slot inside the jack for the sleeve is on the clip side.

Hi juniper.
ya you are on the right track. thats what i am talking about. the jack i am talking about has holes that are similar to the black plug in the picture http://www.blackbox.com/Catalog/Deta...4,867&mid=3857
so what u mean for instance am using (568b, hope it is the most popular out there), the i must put the white-orange wire up, then the orange down, then white green up, like this.......

by the way can i use it for CAT5 cables coz its written CAT6 MODULAR PLUGS (in the link)

thanks.

In addition, all CAT6 components must be backward compatible with CAT5e, CAT5, and CAT3. If different category components are used with CAT6 components, then the channel will achieve the transmission performance of the lower category. For instance, if CAT6 cable is used with CAT5e jacks, the channel will perform at a CAT5e level.

You could use CAT 5 cable and CAT 6 plugs, but why? They are more expensive, and since the weakest link, so to speak, will be the limiting factor it won't give better performance.

568b is the standard and a crossover standard is 568b to 568a.

The CAT5 plug would be straight accross not 4 up and 4 down but it will work just fine as its backwards compatible. The catagory is what determines the frequency it can sustain (usualy just more or less twists in the pairs of wires) like Erik said you will be at the weakest link Cat which would be 5E in your case which by the way can do 10Gb so no biggy.

ok guys thanks for the usefull info.
