分光器在對正常鏈路進(jìn)行分光時，會按照光功率相對應(yīng)的比例分配到多條分光后的鏈路，因此分光后鏈路的光功率會有一定的衰減，同時由于光纖及連接器等自身的損耗和色散，也可能會導(dǎo)致分光下來的鏈路的光功率較低，繼而導(dǎo)致后端設(shè)備接收到的數(shù)據(jù)出現(xiàn)誤碼甚至收不到數(shù)據(jù)等現(xiàn)象。解決這種情況就需要在鏈路中增加一個光放大器（OEO），對分光后鏈路的光功率進(jìn)行放大，確保后端設(shè)備接收到的數(shù)據(jù)準(zhǔn)確。

于實(shí)現(xiàn)光信號分路/合路或用于延長光纖鏈路的元件，屬于光被動元件領(lǐng)域，在電信網(wǎng)路、有線電視網(wǎng)路、用戶回路系統(tǒng)、區(qū)域網(wǎng)路中都會應(yīng)用到。光纖耦合器可分標(biāo)準(zhǔn)耦合器(屬于波導(dǎo)式，雙分支，單位1×2，亦即將光訊號分成兩個功率)、直連式耦合器(連接2條相同或不同類型光纖接口的光纖,以延長光纖鏈路)、星狀/樹狀耦合器、以及波長多工器(WDM，若波長屬高密度分出，即波長間距窄，則屬于DWDM)，制作方式則有燒結(jié)(Fuse)、微光學(xué)式(Micro Optics)、光波導(dǎo)式(Wave Guide)三種，而以燒結(jié)式方法生產(chǎn)占多數(shù)(約有90%)。 </p> <p> <span style="font-size:12px;">燒結(jié)方式的制作法，是將兩條光纖并在一起燒融拉伸，使核芯聚合一起，以達(dá)光耦合作用，而其中重要的生產(chǎn)設(shè)備是光纖熔接機(jī)，也是其中的重要步驟，雖然重要步驟部份可由機(jī)器代工，但燒結(jié)之后，仍須人工作檢測封裝，因此人工成本約占10~15%左右，再者采用人工檢測封裝須保品質(zhì)的一致性，這也是量產(chǎn)時所必須克服的，但技術(shù)困難度不若DWDM 模塊及光主動元件高，因此初期想進(jìn)入光纖產(chǎn)業(yè)的廠商，大部分會從光耦合器切入。</span> 保偏光纖耦合器的不同參數(shù)會有不同的應(yīng)用。蘇州保偏光纖耦合器廠家</p><p style="text-indent:25px">保偏光纖耦合器的多種系列總有一款是您滿意。蘇州保偏光纖耦合器廠家</p><p> 光分路器以一定的分光比將一個輸入光信號分成多個輸出光信號。例如，一個分光比為1:4的光分路器可以將一個光信號平均分成四份，然后在四個不同的通道內(nèi)傳輸。此外，光分路器還可以端接不同種類的連接器，其封裝方式通常為盒式或不銹鋼管式兩種，盒式光分路器一般使用2mm或3mm外徑的光纜，而不銹鋼管式光分路器一般使用0.9mm外徑的光纜。 </p> <p> <span style="font-size:12px;">使用單/多模光纖和保偏光纖多端口設(shè)計(jì)，光纜的長度和直徑可定制有多個分光比，從1:99到50:50封裝方式分為管式和盒式，有熔融拉錐型（FBT）光分路器和平面波導(dǎo)型（PLC）光分路器兩種端接的連接器有PC、UPC和APC三種研磨方式可以端接FC、SC、ST、LC和MU連接器。</span>
