數(shù)字傳輸系統(tǒng)是把輸入的信號變換成“1”，“0”表示的脈沖信號，并以它作為傳輸信號。在接受端再把它還原成原來的信息。這樣光源的非線性對數(shù)字碼流影響很小，再加上數(shù)字通信可以采用一些編碼糾錯的方法，且易于實(shí)現(xiàn)多路復(fù)用，因此數(shù)字傳輸系統(tǒng)占有很大的優(yōu)勢，并在很多地方得到了***的應(yīng)用。專業(yè)銷售SDH光傳輸設(shè)備，PTN設(shè)備，OTN設(shè)備。推薦深圳市騰云科創(chuàng)信息咨詢有限公司，服務(wù)周到，產(chǎn)品質(zhì)量，信譽(yù)良好。
