style="text-indent:25px">光端機，顧名思義就是光信號傳輸?shù)慕K端設備。由于目前光纖的大幅降價及其在各個領域的廣范應用，光端機的使用量越來越大，各光端機生產(chǎn)廠家也如雨后春筍般相繼出現(xiàn)。但因其中一部分技術在光端機市場還很小時就已比較成熟，開發(fā)新技術又需耗費大量人力、物力，所以光端機生產(chǎn)廠家多以中小企業(yè)為主，各種品牌層出不窮，但質(zhì)量卻大相徑庭。視頻監(jiān)控中的光端機是光通信系統(tǒng)中的傳輸設備，主要是進行光電轉(zhuǎn)換及傳輸功用。一般用于電信、電力、監(jiān)控、工業(yè)控制、視頻傳輸?shù)裙δ?，在各個行業(yè)有著廣的應用。北京網(wǎng)絡光端機的價格模擬光端機就是將要傳輸?shù)男盘栠M行幅度或頻率調(diào)制然后將調(diào)制好的電信號轉(zhuǎn)化成光信號。</p><div

style="text-indent:25px">模擬光端機與數(shù)字光端機處理方式的不同，引起的視頻、音頻、數(shù)據(jù)信號信號失真、變畸變、干擾不同。模擬光端機由于要進行調(diào)幅、調(diào)頻、調(diào)相，所以模擬信號的幅度的變化與載波信號因調(diào)制而引起的幅度變化是否為一一對應的線形關系成為擬光端機質(zhì)量好壞的關鍵，到目前為止，很難做到真正線性調(diào)制，非線形必同時調(diào)制好的載波信號還要調(diào)制光信號，光信號的非線性也是一個非常重要的因素，眾所周知，光器件的非線性工作電壓的穩(wěn)定性、光發(fā)射功率有很大的影響，因此光器件在生產(chǎn)時需進行7-10天的熱循環(huán)老化等等工藝選只能做到將這種變換控制在一定的范圍；光信號在光纖中長距離傳輸，會引起光信號的功率衰減，傳輸頻率漂移信號色散效應同樣也會引起光信號畸變；光信號到達接收端，接收光器件仍然要引起非線性失真，由光電轉(zhuǎn)換后解調(diào)，解調(diào)與調(diào)制一樣會產(chǎn)生非線性畸變。所以綜合模擬光端機，從輸入信號調(diào)制-電光轉(zhuǎn)換-光輸出-光電轉(zhuǎn)換-都會引起非線形失真，而這些信號畸變失真是固有的，所以也必然是不可消除的，因此模擬光端機傳輸視頻圖象據(jù)的效果很難達到很滿意的效果。數(shù)字式光端機只是只有模數(shù)轉(zhuǎn)換的量化誤差(如1V視頻信號12bits時只是為2起信號畸變。</p><p style="text-indent:25px">光端機在安防領域有著重要的地位光端機在目前安防系統(tǒng)中扮演的是傳輸數(shù)據(jù)的角色，占據(jù)安防領域中重要的地位，他解決遠距離傳輸和大容量傳輸。因為前端攝像頭等采集源的接口不同，光端機必須成對使用，一個光端機把前端的輸入信號轉(zhuǎn)換成光信號，另一個光端機再把光信號還原成輸入信號送給終端。這也意味著在安防施工的過程中，針對每一個布點線路我們都必須配用一對光端機。在安防解決方案中，各個方向的布點數(shù)據(jù)，都會匯集到監(jiān)控中心，如果我們能對光端機進行整合，在光端機的設計中也引入交換機的概念，采用一個多路光端機來接入來自不同布點線路的光信號，我們就可以省去一半數(shù)量的光端機，對大型項目來說可以大量節(jié)約成本。這種集中管理的方式這有別于一般的多模光端機，多模形式在視頻圖像傳輸時，帶寬(針對模擬調(diào)制)和傳輸速率(針對數(shù)字式)有較大的限制，特別是因色散的影響明顯限制了采用高速率傳輸?shù)姆菈嚎s數(shù)字光端機在傳輸距離、容量方面的應用。光纖中只有"有光"和"無光"兩種狀態(tài)，對光源線性要求不高或幾乎沒有要求，避免了信號在處理過程中的損失。</p><div

II圖象壓縮數(shù)字光端機，另一種是全數(shù)字非壓縮視頻光端機。數(shù)字光端機的視頻采用8位數(shù)字編碼。北京網(wǎng)絡光端機的價格</p><p style="text-indent:25px">光端機的價格由于應用領域、產(chǎn)品質(zhì)量、品牌、服務的區(qū)別，差異較大。天津視頻光端機生產(chǎn)廠家</p><p
