輸入光的哪一部分將被耦合進第二根光纖，取決于工作波長、兩條纖芯之間的距離以及耦合區(qū)域內(nèi)的纖芯直徑。因此，通過確定耦合區(qū)域的大小，我們將能夠控制輸出功率比，即耦合比。50:50的耦合比十分流行，而1:99則用于監(jiān)控EDFA內(nèi)部的輸入和輸出信號。 </p> <p> <span style="font-size:12px;">FBT耦合器具有如下三個關(guān)鍵優(yōu)勢：低損耗過程：光纖耦合是一個低損耗的過程，實際上，在芯模到耦合模再到芯模的轉(zhuǎn)換過程中是沒有損耗的。因此，我們不得不說損耗是光通過一個短包層長度所造成的。不過，耦合器的插入損耗相當高，并且取決于耦合比。?無逆反射：光纖決不會再耦合過程中離開光纖結(jié)構(gòu)，所以它決不會經(jīng)過任何的接口。因此，此類型耦合器本身不會造成逆反射。實際上，此類型耦合器的技術(shù)資料中并沒有包含這一規(guī)范。便于連接：由于耦合器是由普通光纖制成，因此FBI能夠與傳輸光纖非常方便地進行連接，并且損耗低。</span> </p><p> 一個具有50:50輸出比的耦合器，也就是被稱為3?dB耦合器的分路器。這種簡單的裝置可用作樹狀或星形耦合器的構(gòu)建塊。然而，這并不是比較好的方法，因為我們需要M?=?(N/2)?log2N?3-dB的耦合器以得到一個NxN并且發(fā)射進入每一端口的功率只有1/N會出現(xiàn)在每一個輸出端口。這就是為什么廣播WDM網(wǎng)絡的新一代樹狀和星形耦合器直接使用FBT技術(shù)來制造。 </p> <p> <span style="font-size:12px;">均勻性是耦合器的一個特性，用于確保相等的分光比。例如，一個理想的1×2耦合器將輸入功率均勻分流后進入兩個端口。但在現(xiàn)實中，每一個輸出端口的功率會偏離50:50的均分比。造成這一非均勻性的物理原因在于，制作過程中不同耦合插入的損耗不同。</span>

光纖分路器的穩(wěn)定性也是一個重要的指標，所謂穩(wěn)定性是指在外界溫度變化，其它器件的工作狀態(tài)變化時，光纖分路器的分光比和其它性能指標都應基本保持不變，實際上光纖分路器的穩(wěn)定性完全取決于生產(chǎn)廠家的工藝水平，不同廠家的產(chǎn)品，質(zhì)量懸殊相當大。 </p> <p> <span

style="text-indent:25px">光纖拉錐耦合器損耗對光波長敏感，一般要根據(jù)波長選用器件，這在三網(wǎng)合一使用過程是致命缺陷，因為在三網(wǎng)合一傳輸?shù)墓庑盘栍?310nm、1490nm、1550nm等多種波長信號。均勻性較差，均勻性是指均分光的分路器各輸出端的插入損耗變化量。1X4標稱較大相差1.5dB左右，1×8以上相差更大，不能確保均勻分光，可能影響整體傳輸距離。插入損耗隨溫度變化變化量大(TDL);插入損耗是指某一端口輸出光功率與輸入端光功率之比。插入損耗是由兩個部分組成：一部分是附加損耗，另一部分是分光比因素;器件的分光比不同，插入損耗也不相同，因此;在標準中也沒做具體規(guī)定。多路分路器(如1×16、1×32)體積比較大，可靠性也會降低，安裝空間受到限制。常州邁岐保偏濾波耦合器定制價格</p></p><br
