style="text-indent:25px">4路視頻光端機(jī)在面對瞬間干擾時(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。河南音頻光端機(jī)批發(fā)廠家在模擬傳輸系統(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。</p><div

style="text-indent:25px">光纖收發(fā)器與光端機(jī)的區(qū)別是什么？相同之處：都要進(jìn)行光電轉(zhuǎn)換。不同之處：收發(fā)器只是進(jìn)行光電轉(zhuǎn)換，不改變編碼，不對數(shù)據(jù)作其他處理，收發(fā)器是針對以太網(wǎng)來說，跑802.3協(xié)議，只用于點(diǎn)對點(diǎn)的連接。光端機(jī)，除了光電轉(zhuǎn)換的工作以外，還要對數(shù)據(jù)信號(hào)進(jìn)行復(fù)用和解復(fù)用。通常光端機(jī)出來的是對E1線路，SDH，PDH光端機(jī)主要用于電信運(yùn)營商，用于提供多點(diǎn)到點(diǎn)的數(shù)據(jù)電路；視頻光端機(jī)主要用于安防監(jiān)控，遠(yuǎn)程教育，視頻會(huì)議等對視頻傳輸要求適時(shí)比較高的領(lǐng)域，同時(shí)可以傳輸控制，開關(guān)量，語言，以太網(wǎng)等信號(hào)來滿足多業(yè)務(wù)應(yīng)用需求，所以我們有時(shí)候也將其稱為綜合光端機(jī)。</p><p
