style="text-indent:25px">路視頻光端機(jī)主要用于傳輸視頻信號，用戶在使用過程中可能出現(xiàn)圖像不清晰，有雪花的情況，這種情況的出現(xiàn)多半是由于光纖鏈路衰減過大或前端視頻線纜過長受交流電磁干擾所致，首先檢查尾纖是否彎折過度了，若過度彎折則打直;其次檢查光口和終端盒法蘭盤連接處是否連接可靠法蘭磁芯是否破損等;如果沒問題再次檢查光口和尾纖是否過臟，如果過臟應(yīng)用酒精和棉花清潔待干后再插入;較后檢查視頻傳輸線路是否有會引起電磁干擾的物體，如果有去掉干擾。貴州視頻光端機(jī)品牌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)制信號的幅度變化而變化。</p><div

style="text-indent:25px">如何選擇合適的視頻光端機(jī)的問題就擺在了大家面前，在此，謹(jǐn)就多年的行業(yè)經(jīng)驗(yàn)與有意于視頻光端機(jī)選型應(yīng)用的讀者共享。光端機(jī)選購注意事項:從發(fā)送到光纖上的信號來分，光端機(jī)可分為基于模擬技術(shù)的模擬光端機(jī)和基于數(shù)字技術(shù)的數(shù)字光端機(jī)。模擬光端機(jī)其工作原理不外乎調(diào)制解調(diào)、濾波和信號混合等。不論是LED 還是LD，其光電調(diào)制特性都不是線性的，在信號傳輸過程中難免出現(xiàn)失真、干擾等模擬處理中不可避免的問題，且在大容量傳輸和多業(yè)務(wù)混合傳輸方面有難以克服的技術(shù)難點(diǎn)。</p><p style="text-indent:25px">其中一部分技術(shù)在光端機(jī)市場還很小時就已比較成熟，開發(fā)新技術(shù)又需耗費(fèi)大量人力、物力，所以光端機(jī)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(jī)是光通信系統(tǒng)中的傳輸設(shè)備，主要是進(jìn)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埽诟鱾€行業(yè)有著廣的應(yīng)用。常說的光端機(jī)指的是用于監(jiān)控系統(tǒng)用來傳輸視頻、數(shù)據(jù)、以太網(wǎng)、音頻等綜合信息的光端機(jī)。主要分模擬光端機(jī)和數(shù)字光端機(jī)。基于傳輸?shù)慕橘|(zhì)的不同有單模光端機(jī)和多模光端機(jī)之分。光端機(jī)的使用中要保證連續(xù)、正常供電。</p><div
