style="text-indent:25px">可調(diào)諧激光器在光傳輸系統(tǒng)中可能的應(yīng)用方式很多，如對于實(shí)驗(yàn)室，可以利用可調(diào)諧激光器模擬整個波段的單波光源進(jìn)行相關(guān)的實(shí)驗(yàn)等?？烧{(diào)諧激光器在DWDM光傳輸系統(tǒng)中可自動實(shí)施保護(hù)和恢復(fù)倒換的通道層保護(hù)的應(yīng)用。常用的保護(hù)光通道業(yè)務(wù)運(yùn)行的方法有：一種是為設(shè)備提供備份的硬件，當(dāng)單元出現(xiàn)故障時，通過人工方式進(jìn)行緊急更換的替代裝置;第二種方法是在發(fā)射端為光轉(zhuǎn)發(fā)單元配置保護(hù)裝置。保護(hù)裝置處在上電狀態(tài)，隨時可以替代故障單元進(jìn)行工作。另外還有一種實(shí)現(xiàn)通道保護(hù)的方法，是使用固定波長的光轉(zhuǎn)發(fā)單元，在WDM系統(tǒng)發(fā)送端設(shè)備所有的通道中，指定一部分光通道保護(hù)通道。在受保護(hù)的通道光轉(zhuǎn)發(fā)單元出現(xiàn)故障時，將故障單元的輸入業(yè)務(wù)切換到保護(hù)通道的光轉(zhuǎn)發(fā)單元輸入端。因此，由于可調(diào)諧激光器自身的優(yōu)點(diǎn)，使得其在DWDM系統(tǒng)大有用武之地。</p><p style="text-indent:25px">可調(diào)諧激光器校準(zhǔn)裝置通常由光波長計(jì)、標(biāo)準(zhǔn)光纖功率計(jì)(包括標(biāo)準(zhǔn)的探測器)、光譜分析儀以及標(biāo)準(zhǔn)光纖等構(gòu)成。在校準(zhǔn)裝置中比較重要的是一臺高分辨率、高準(zhǔn)確度、可溯源的標(biāo)準(zhǔn)光纖功率計(jì)。標(biāo)準(zhǔn)光纖功率計(jì)應(yīng)滿足校準(zhǔn)所要求的波長范圍和功率范圍，根據(jù)實(shí)際可調(diào)諧激光器的情況，通常選用的波長范圍為(800～1700)nm，功率范圍為(-90～+10)dBm。裝置中對標(biāo)準(zhǔn)光纖功率計(jì)的測量不確定度要求較高，通常含標(biāo)準(zhǔn)光探測器在內(nèi)的標(biāo)準(zhǔn)光纖功率計(jì)在定標(biāo)點(diǎn)處的不確定度要求在2.5%以內(nèi)(在參考條件下)。標(biāo)準(zhǔn)光纖功率計(jì)還應(yīng)具有良好的線性。構(gòu)成可調(diào)諧激光器的諧振腔只在很窄的波長范圍內(nèi)才有很低的損耗。</p><div
