等型式，按光纖端面形狀分有FC、PC(包括SPC 或UPC)和APC 等類型。目前應(yīng)用較廣的只有FC、SC 和ST 三種。一般長(zhǎng)距離或大容量通信大多使用FC或SC

style="text-indent:25px">4路視頻光端機(jī)在面對(duì)瞬間干擾時(shí)，需要很強(qiáng)的抵抗力才能有效的避免破壞。各個(gè)廠家根據(jù)設(shè)備的保護(hù)使用不同的措施，使4路視頻光端機(jī)具有更強(qiáng)的使用壽命。 (1)、4路視頻光端機(jī)瞬態(tài)干擾的危害:由于它干擾頻率高、持續(xù)時(shí)間短、干擾幅度大(成百上千伏)、它可以燒壞4路視頻光端機(jī)的RS-485接口芯片、主芯片等關(guān)鍵部位，卻不留痕跡，尤其是夏季雷雨季節(jié)，這種破壞力影響很大，使用戶、商家和廠家都十分傷腦筋。 (2)、4路視頻光端機(jī)瞬態(tài)干擾的產(chǎn)生:瞬態(tài)干擾產(chǎn)生于大型感性負(fù)載，如電機(jī)、變壓器、繼電器等設(shè)備的開關(guān)轉(zhuǎn)換，以及雷電的發(fā)生過(guò)程中，它往往以靜電感應(yīng)的方式入侵4路視頻光端機(jī)。 (3)、4路視頻光端機(jī)瞬態(tài)干擾的解決方法:盡管4路視頻光端機(jī)制造商采用了各種保護(hù)手段，如隔離法(光耦隔離)、旁路法(自恢復(fù)二極管)、吸收法(雙向避免二極管等)，這些基本可以有效的解決瞬態(tài)干擾造成的破壞。光耦隔離是指光耦隔離電路使被隔離的兩部分電路之間沒有電的直接連接，主要是防止因有電的連接而引起的干擾，特別是低壓的控制電路與外部高壓電路之間。河南視頻光端機(jī)廠家光端機(jī)，就是光信號(hào)傳輸?shù)慕K端設(shè)備。</p><div

style="text-indent:25px">光端機(jī)的系統(tǒng)原理光傳輸系統(tǒng)由三部分組成：光源（光發(fā)送機(jī)），傳輸介質(zhì)、檢測(cè)器（光接收機(jī)）。按傳輸信號(hào)劃分，可分為數(shù)字傳輸系統(tǒng)和模擬傳輸系統(tǒng)。在模擬傳輸系統(tǒng)中，是把輸入信號(hào)變?yōu)閭鬏斝盘?hào)的振幅（頻率或相位）的連續(xù)變化。光纖的模擬傳輸系統(tǒng)是把光強(qiáng)進(jìn)行模擬調(diào)制，其光源的調(diào)制功率隨調(diào)制信號(hào)的幅度變化而變化。但由于光源的非線性較嚴(yán)重，因此其信噪比、傳輸距離和傳輸頻率都十分有限。數(shù)字傳輸系統(tǒng)是把輸入的信號(hào)變換成“1”，“0”表示的脈沖信號(hào)，并以它作為傳輸信號(hào)。在接受端再把它還原成原來(lái)的信息。這樣光源的非線性對(duì)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(cuò)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(shì)，并在很多地方得到了應(yīng)用。視頻光端機(jī)又分為模擬光端機(jī)和數(shù)字光端機(jī)。</p><div
