在我們家庭局域網(wǎng)中,傳輸介質(zhì)通常使用的都是百兆網(wǎng)線,還有另外一種常用的是千兆網(wǎng)線,那兩者使用上都有什么區(qū)別呢?百兆網(wǎng)線和千兆網(wǎng)線做法上又有什么區(qū)別呢?

根據(jù)網(wǎng)線的分類來說,所有的網(wǎng)線在外皮上都有種類標(biāo)識,CAT5 CAT5E 分別代表了五類線超五類線,也就是我們說的百兆網(wǎng)線;CAT6 CAT6A 則代表了六類線和超六類線也就是千兆網(wǎng)線,其實千兆也可以用超五類線,只是我們推薦最好用6類線,因為線的優(yōu)劣性能各不一樣,千兆用超5類線不是很保險。

在使用上,其實千兆網(wǎng)線和百兆網(wǎng)線是沒什么區(qū)別的,千兆網(wǎng)線完全兼容百兆網(wǎng)絡(luò),當(dāng)然,百兆網(wǎng)線的傳輸速率沒有千兆的高,所以不能向上兼容。也就是說,在家庭網(wǎng)絡(luò)環(huán)境下,使用百兆網(wǎng)線和千兆網(wǎng)線都是可行的,用千兆網(wǎng)線就不必?fù)?dān)心家庭寬帶升級產(chǎn)生的重新布線的麻煩,不過相對來說千兆網(wǎng)線的價格也貴很多。

下面就舉幾個常見例子:

      1、千兆主干交換機(jī),接千兆分交換機(jī),用什么線?六類線(CAT6) 
      2、千兆主干交換機(jī),接百兆分交換機(jī),用什么線?六類線(CAT6) 
      3、千兆主干交換機(jī),接新服務(wù)器,用什么線?六類線(CAT6) 
      4、千兆主干交換機(jī),接老服務(wù)器,用什么線?超五類(CAT5E),跑100Mbps 。
      5、千兆分交換機(jī),接新機(jī)器,用什么線?預(yù)算多就用六類線(CAT6),起碼要用超五類(CAT5E)。
      6、百兆分交換機(jī),接舊機(jī)器,用什么線?用超五類,原來有可以不動,質(zhì)量太差的話剪掉,全新布過超五類(CAT5E)。

      在傳輸數(shù)據(jù)方法來說,百兆網(wǎng)線的線芯是8芯,但上傳和下載只用到了其中的4根,而千兆網(wǎng)線需要完全用到8根。

 另外在線芯的排布上,千兆網(wǎng)線的線芯中間有個十字形的塑料架,用來把四組8芯的線分開,這個百兆網(wǎng)線是沒有的,這也讓千兆網(wǎng)線的做法又提高了難度。

那么問題就來了:

不止一個朋友問,我用千兆工業(yè)交換機(jī)接百兆網(wǎng)線行嗎?    

千兆交換機(jī)可以接百兆網(wǎng)線,只是這條線路上只能使用百兆網(wǎng)了,無法達(dá)到千兆的水平。

千兆和百兆網(wǎng)線都用的是T586B標(biāo)準(zhǔn)的。(除非設(shè)備之間需要用到交叉線。)

連接千兆工業(yè)交換機(jī)如果要達(dá)到千兆速度,最好使用六類線,五類線不可以的,超五類線看線的質(zhì)量和傳輸?shù)木嚯x。

百兆網(wǎng)線和千兆網(wǎng)線的水晶頭制作方法一樣嗎? 答案是肯定的,方法完全一樣。

但是,千兆網(wǎng)線做好測試的時候,一定要測試1-8號線全通,因為千兆網(wǎng)線1-8芯都工作。
