style="text-indent:25px">光纖在光傳輸中的應(yīng)用根據(jù)傳輸設(shè)備的不同,光纖線路在光傳輸網(wǎng)絡(luò)中主要有兩種應(yīng)用:一種為數(shù)字傳輸,一般為PDH、SDH制式。PDH目前較少用于廣播電視傳輸,多用于數(shù)據(jù)傳輸。SDH多用于組建干線傳輸網(wǎng),也是目前廣電系統(tǒng)采用的傳統(tǒng)模式。另一種為AM模擬傳輸,AM模擬有線電視光傳輸系統(tǒng)又可分為直接調(diào)制調(diào)幅和外調(diào)制調(diào)幅系統(tǒng)。直接調(diào)制調(diào)幅系統(tǒng)是半導(dǎo)體、激勵(lì)器直接將光強(qiáng)度調(diào)制,將調(diào)頻電信號(hào)轉(zhuǎn)換成調(diào)幅光信號(hào)進(jìn)行傳輸。(DFB)激勵(lì)器,其光譜線窄、線性好、輸出功率高、光波長(zhǎng)為1310nm,目前使用**多,適用于中短距離傳輸。為廣播電視系統(tǒng)傳輸?shù)闹鞴饫w的連接分為熔接和磨接,無論何種連接都會(huì)產(chǎn)生接頭損耗。1310nm的光纖衰減系數(shù)為0.35dB/km。無論信號(hào)傳輸遠(yuǎn)近,光纜的連接都需要進(jìn)行光纖熔接,其接頭熔接損耗一般在0.05dB以下。因此在計(jì)算光纖自動(dòng)損耗時(shí)還應(yīng)考慮接頭和其他損耗(2km一般取1dB)。</p><p> SDH 光傳輸設(shè)備故障故障處理方法 </p> <p> <p> 拔插法 </p> <p> 有些故障可以通過拔插單板來排除，現(xiàn)在的 SDH 設(shè)備都支持帶電熱插拔，拔插法對(duì)于故障的處理十分有效，拔插單板的時(shí)候要注意正確使用防靜電手鐲，避免由于不使用防靜電手鐲拔插單板時(shí)損壞單板，造成不必要的損失。該方法對(duì)于一些故障來說快速便捷。 </p> <p> <p> 替換法 </p> <p> 如果拔插法還不能解決故障的話，替換法也是一種選擇。所謂替換法，就是用正常工作的元件去替換被懷疑有故障的元件，從而實(shí)現(xiàn)對(duì)故障的定位，達(dá)到排除故障的目的。這里所提到的元件是指任何設(shè)備，無論是復(fù)雜到一個(gè)設(shè)備或者是小到一段線纜。替換法主要用于排除用以傳輸?shù)耐獠吭O(shè)備問題，比如電纜、供電設(shè)備、光纖和交換機(jī)等，或者排除某個(gè)單站內(nèi)的單板問題。舉例如下：當(dāng)某一個(gè)站的光板出現(xiàn)警告，有可能是收、發(fā)光纖的正反接錯(cuò)問題?；Q接收線，如果報(bào)警消失則說明確實(shí)是光纖接反導(dǎo)致的。如若支路板的信號(hào)有性能超值或者信號(hào)丟失的警告，有可能是中繼線或交換機(jī)的問題，可以與其他工作正常的通道互換，若警告轉(zhuǎn)移，則可以證明中繼線或交換機(jī)的問題，若不是，則可能是傳輸故障。
