1.綜合布線(xiàn)系統(tǒng)采用結(jié)構(gòu)化的星型拓?fù)洳季€(xiàn)方式和標(biāo)準(zhǔn)接口，較大提高了整個(gè)網(wǎng)絡(luò)的可靠性及可管理性，大幅降低系統(tǒng)的管理維護(hù)費(fèi)用； 2.模塊化的系統(tǒng)設(shè)計(jì)提供良好的系統(tǒng)擴(kuò)展能力及面向未來(lái)應(yīng)用發(fā)展的支持，充分保證用戶(hù)在布線(xiàn)方面的投資，提供用戶(hù)長(zhǎng)遠(yuǎn)的效益。 3.綜合布線(xiàn)系統(tǒng)較好地解決了傳統(tǒng)布線(xiàn)方法存在的許多問(wèn)題，提供了具有長(zhǎng)遠(yuǎn)效益的先進(jìn)可靠的解決方案。隨著現(xiàn)代信息技術(shù)的飛速發(fā)展，綜合布線(xiàn)系統(tǒng)將成為現(xiàn)代智能建筑不可缺少的基礎(chǔ)設(shè)施。蘇州電話(huà)布線(xiàn)系統(tǒng)批發(fā)廠(chǎng)家綜合布線(xiàn)系統(tǒng)將一座建筑物中的纜線(xiàn)延伸到另一座建筑物的布線(xiàn)部分。</p><div

提到如何選擇綜合布線(xiàn)系統(tǒng)，首先有兩個(gè)概念要分清，那就是帶寬（以MHZ來(lái)度量）和數(shù)據(jù)傳輸速率（以 Mbit／S來(lái)度量）。分不清這兩個(gè)概念就很難作出正確的選擇。關(guān)于二者的定義和具體含義可以參考有關(guān)的技術(shù)文章。這里要指出的是二者之間的關(guān)系，這種關(guān)系與編碼方式等技術(shù)有關(guān)，但不一定是一對(duì)一的關(guān)系。例如ATM155，其中155是指數(shù)據(jù)傳輸?shù)乃俾?，?55Mbit／S，而實(shí)際的帶寬只有80MHZ；又如1000Mbit／S千兆位以太網(wǎng)，由于采用4對(duì)線(xiàn)全雙工的工作方式，對(duì)其傳輸帶寬的要求只有100MHZ。在計(jì)算機(jī)網(wǎng)絡(luò)作業(yè)中，較廣使用的是數(shù)據(jù)傳輸速率，而在電纜行業(yè)中使用的則是帶寬，所以不要將二者混淆。</p><p style="text-indent:25px">合理選擇綜合布線(xiàn)系統(tǒng):1.6類(lèi)、7類(lèi)的標(biāo)準(zhǔn)還未正式出臺(tái)，6類(lèi)系統(tǒng)的安裝規(guī)范和方法目前也沒(méi)有形成，更重要的是有關(guān)6類(lèi)或7類(lèi)系統(tǒng)的測(cè)試規(guī)范和方法還沒(méi)有。目前普遍使用的測(cè)試設(shè)備仍是基于100MHZ的5類(lèi)系統(tǒng)標(biāo)準(zhǔn)，所以即使用戶(hù)在工程中采用了6類(lèi)產(chǎn)品，也無(wú)法知道所采用的布線(xiàn)系統(tǒng)是否符合6類(lèi)系統(tǒng)要求。究竟什么樣的產(chǎn)品才算是6類(lèi)產(chǎn)品，恐怕誰(shuí)也說(shuō)不清楚。 2. 隨著通信技術(shù)的飛速發(fā)展，鋼纜終將被淘汰，淘汰的主要原因就是帶寬、傳輸距離以及電磁波擴(kuò)散和干擾問(wèn)題，而替代它的將是光纖甚至未來(lái)的某種傳輸介質(zhì)。有資料表明全光纖網(wǎng)已在美國(guó)興起，10Gbit／S的以太網(wǎng)也已經(jīng)在實(shí)驗(yàn)室中誕生了。無(wú)論是對(duì)廠(chǎng)商還是用戶(hù)來(lái)說(shuō)，全光纖的局域網(wǎng)都將會(huì)更具吸引力。綜合布線(xiàn)系統(tǒng)使話(huà)音和數(shù)據(jù)通信設(shè)備、交換設(shè)備和其他信息管理系統(tǒng)彼此相連。</p><div
