On cable

Cable crystal head there are two configurations, one is directly connected to the interconnection method of a cross interconnection method.

Is cross-line approach: using a 568 A standard, using a 568 B standard.

Parallel (straight) line of approach is: two with the same 568 A standard or 568 B standard. (Typically used are 568 B parallel (straight) line of approach)

568 A Standard: white and green blue and white orange and blue orange white brown brown

568 B Standard: White White Green blue bluish green Orange Orange Brown White Brown

 

 

 

 

A cross-connection

1-3,2-6 cross connection. Although there are eight four pairs of twisted-pair wire, but in fact the network uses only four of which, i.e. 1, 2 and 3, pin 6 of the first crystal, which respectively function as sending and receiving the role of the signal. This crossover cable core wire arrangement rule is:

One end of the cable the other end of the first pin 3 feet connected, at one end of the cable 6 feet 2 feet of the other end is connected, correspond to the other foot. This arrangement is made out commonly known as "cross-line, for example, when the core end of the wire line sequential order of left to right: white and green, green, orange and white, blue, white, blue, orange, white brown, brown , the other end of the core sequence is from left to right should be followed: white orange, orange, green, white, blue, white, blue, green, white brown, brown as shown below:

 

 Second, the method directly connected

2.1 568 A standard

 

2.2, 568 B standard

 

 2.3,100M connection

"100M connection." This is one of the most popular cable production rules. The so-called connection 100M, 100M means that it can meet the bandwidth of communication speed. Although it is one to one connection, but each foot color is fixed. specifically is:

Pin 1 - orange white, pin 2 - orange, pin 3 - green and white, 4 feet - blue, 5 feet - blue, 6 feet - green, pin 7 - - brown white, 8 feet - brown, can be seen, the cable core wire 4 are not all arranged adjacent to pin 1, pin 3, pin 5 and pin 7 comprises two pairs of wire , but the order has been disturbed.
