對于568A和568B,二者沒有本質(zhì)的區(qū)別,只是顏色上的區(qū)別,本質(zhì)的問題是要保證:
(1)1、2線對是一個繞對
(2)3、6線對是一個繞對
(3)4、5線對是一個繞對
(4)7、8線對是一個繞對
(1)用HUB或交換機(jī)相互組網(wǎng)時,一根線的兩頭必須用同一個標(biāo)準(zhǔn)制作,在同一個HUB或交換機(jī)上最好只用一種標(biāo)準(zhǔn)制作網(wǎng)線;
(2)當(dāng)只有兩臺計(jì)算機(jī)不用HUB或交換機(jī)時,網(wǎng)線的一頭需采用568A標(biāo)準(zhǔn),另一頭則應(yīng)采用568B標(biāo)準(zhǔn),這是因?yàn)榫W(wǎng)卡的腳1和腳2用作發(fā)送數(shù)據(jù),而腳3和腳6用作接收數(shù)據(jù)引腳。兩種不同的標(biāo)準(zhǔn)正好和腳1、2、3、6相對應(yīng)。
(3)不管兩臺計(jì)算機(jī)的物理位置多近,實(shí)踐證明,網(wǎng)線的長度應(yīng)大于1.5米,否則也會發(fā)生數(shù)據(jù)傳輸時斷時續(xù)的現(xiàn)象。
