DSL、 網線和光纖的區別

兩家想共用一個寬帶,間隔兩百五十米,有什么好方法?那么,目前的寬帶並不是非常昂貴,像中國移動的2億寬帶只有幾百元一年,有條件的,或重新安裝一個寬帶最好。當然,如果你必須這么做,有很多方法,所以看看吧。

一、通過一個中繼器來實現。我們都知道,超5類或6類雙絞網線,超過100米,寛頻斷線,傳輸數據信號系統就會逐漸變弱,到200米後,應該就沒有自己一點就是信號了。可見,拉動網線直接連接,是不現實的。但是,我們教師可以同時通過一個中繼器(如:路由器或交換機)來連接2個100米的網線,250米就需要2個中繼器。當我們降低傳輸速率時,只需要一個中繼器就可以實現。我們手動將6類線路的傳輸速率降低到10Mbps後,實際傳輸距離可以達到150m左右。總體成本也不低,網線+中繼器,400元左右。

二、通過無線網橋實現。250米的距離,2家想共用同一個寬帶,WIFI無線網橋是最簡單的解決問題方案,只需我們要在2家各安裝進行一個企業無線網橋模組就行了,很多不同小區的監控系統都是可以通過研究無線網橋來實現的。無線網橋的優點: 不需要長距離的網絡線路,傳輸距離長(幾公裏不成問題) ,快速而穩定的網絡; 缺點: 2無線網橋之間必須無阻塞。如果2家之間進行比較空曠,無線網橋無疑是我們最好的解決問題方案。無線網橋在某東上,只需300多元發展就可以可以買到自己一組。

三、通過光纖線路來實現。當然,我們也可以通過光纖線路來實現。現在,長途網絡傳輸,基本上都是光纜。250米的距離,對於光纖線來說,是小菜一碟。用光纜連接兩個網絡時,應准備兩個光電轉換器,每個網絡一個。中間的光纜需要購買連接良好的光纜,光纜連接器需要專業的工具制作,比網絡電纜的晶體連接器更麻煩。光纖線+光電轉換器,成本大約500元左右。

以上三種方法,無論哪種方法,都能達到最終的效果。然而,實施起來,都需要有一定的技術含量,也需要一定的成本。那些喜歡玩的人,可以按照上面的方法得到一個。
