根據(jù)光分路器的工作波長，光分路器可以分為單窗口光分路器和雙窗口光分路器。在這里，窗口指的是工作波長。單窗口光分路器只有一個工作波長，而雙窗口光分路器有兩個工作波長。在雙窗口光分路器中，如果使用的是多模光纖，那么其工作波長是850nm和1310nm，如果使用的是單模光纖，那么其工作波長是1310nm和1550nm。 </p> <p> <span style="font-size:12px;">光纖耦合器的原理是，將兩根以上的光纖彼此靠攏進行熔化拉伸，從而產(chǎn)生一個耦合區(qū)。對加熱區(qū)域進行拉伸，直到出現(xiàn)所需要的耦合特性。這一裝置又被稱為熔融拉錐(FBT)耦合器。隨著輸入光纖模場直徑在下錐區(qū)內(nèi)變得越來越大，耦合過程不斷發(fā)生。在耦合區(qū)域內(nèi)，由于兩個纖芯彼此非常靠近，因此一個纖芯與另一個纖芯發(fā)生耦合現(xiàn)象。在纖芯直徑不斷增加的上錐區(qū)，模在芯內(nèi)變得越來越小，終兩個**的模離開了兩根**光纖的輸出端。有時候，兩根光纖會在加熱拉伸前被絞合起來。另一個方法就是研磨光纖端面，使得設(shè)計者可以非常精確地控制耦合的效果。</span> </p><p style="text-indent:25px">FBT熔融拉錐分路器(Fused Bi-conical Tap)就是將兩根（或兩根以上）除去涂覆層的光纖以一定的方法靠擾，在高溫加熱下熔融，同時向兩側(cè)拉伸，終在加熱區(qū)形成雙錐體形式的特殊波導(dǎo)結(jié)構(gòu)，通過控制光纖扭轉(zhuǎn)的角度和拉伸的長度，可得到不同的分光比例。把拉錐區(qū)用固化膠固化在石英基片上插入不銹銅管內(nèi)，這就是光分路器。這種生產(chǎn)工藝因固化膠的熱膨脹系數(shù)與石英基片、不銹鋼管的不一致，在環(huán)境溫度變化時熱脹冷縮的程度就不一致，此種情況容易導(dǎo)致光分路器損壞，尤其把光分路放在野外的情況更甚，這也是光分路容易損壞得主要原因。對于更多路數(shù)的分路器生產(chǎn)可以用多個二分路器組成。一個好的保偏光纖耦合器需要具備哪些特點您了解嗎？</p><div

style="text-indent:25px">保偏光纖耦合器的特點有很多。上海保偏光纖耦合器加工</p><p> 傳輸分配信號用熔融拉錐光纖分路器（Fused Fiber Splitter）熔融拉錐技術(shù)是將兩根或多根光纖捆在一起，然后在拉錐機上熔融拉伸，并實時監(jiān)控分光比的變化，分光比達到要求后結(jié)束熔融拉伸，其中一端保留一根光纖（其余剪掉）作為輸入端，另一端則作多路輸出端。成熟拉錐工藝一次只能拉1×4以下。1×4以上器件，則用多個1×2連接在一起。再整體封裝在分路器盒中。 </p> <p> <span style="font-size:12px;">單模光纖耦合器應(yīng)用廣。2×2單模光纖耦合器具有典型性。它有兩個輸入端和兩個輸出端，中間有一段耦合區(qū)。采用熔化拉伸工藝制作的。拉伸部分形成錐形耦合區(qū)。拉伸使芯區(qū)的光能向芯外擴展;同時，使兩纖芯彼此靠近，這兩種作用都增強了耦合。由1或2輸入的光信號，經(jīng)錐形耦合區(qū)分配，由3和4端輸出。分配的比例稱為耦合比，由拉伸區(qū)的長度控制。</span>
