Color coding for straight cable

Answer 1

To know colour coding of straight cable we need to know some basic facts like where it is use and from where we can generate it.The answeres are crossover or we say straight cable is used for connecting different devices like pc- hub or pc-hub etc,and we can generate it from the basic colour coding of 568a standard.But the question is how?as 568a standard is a standard for twisted pair but its comes under the subcategory of unshield twisted pair cable.so,lets come to the main ans,so here we go--

568a colour coding is

green=gr,white=w,orange=or,blue=bl and brown=br(short form)

1.gr/w

2.gr

3.or/w

4.bl

5.bl/w

6.or

7.br/w

8.br

As we can see above the colour coding of 568a cables{straight(use to connect dissimilar devices like pc-hub)} the basic of colour coding.we can generate the colour coding for cross cable from it-

Straight

As it is

Straight

1.gr/w
