F-tone Networks Optronics’Singlemode wavelength division multiplexer WDM 1310/1550 1X2 2X2 combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. These components have been extensively used in CATV, WDM networks, Fiber sensor and fiber optics instrumentation.

The PM Dense Wavelength Division Multiplexer Module is manufactured toTelcordia standard, based on environmentally stable thin film filter technology.  The PM DWDM Module is designed mainly for signals adding/dropping on OADM, and Mux/Demux DWDM commucation system,with the advantage of high isolation, high extinction ration, low insertion loss, excellent environmental stability, and high power handling capability.

       光波分復(fù)用器屬于波長(zhǎng)選擇性耦合器，是一種用來(lái)合成不同波長(zhǎng)的光信號(hào)或者費(fèi)列不同波長(zhǎng)的光信號(hào)的無(wú)源器件。前者稱(chēng)為“復(fù)用器”后者稱(chēng)為”解復(fù)用器“目前，光纖波分復(fù)用器已經(jīng)成為一種商用無(wú)源器件，其潛在的市場(chǎng)應(yīng)用前景十分廣闊。

光波分復(fù)用器的主要技術(shù)指標(biāo)有：

                                               1.信道插入損耗，表征與光波長(zhǎng)入，相對(duì)應(yīng)的信道功率損耗。

                                               2.信道隔離比（串?dāng)_損耗）表征串入與光波長(zhǎng)信道的功率大小。

Polarization Maintaining Isolation WDM, PMIWDM:The Polarization Maintaining Isolator Wavelength Division Multiplexer combines a WDM and polarization maintaining isolator into a single compact package. It has high extinction ratio, low insertion loss and high isolation. The component is ideal for fiber amplifier and fiber optic system. The PM IWDM has ´ both axis working´ and ´slow axis working´ to be selected.

        DWDM波分復(fù)用器技術(shù)主要應(yīng)用在長(zhǎng)途骨干傳輸網(wǎng)中，它對(duì)光源，放大器等關(guān)鍵器件的性能要求很高，系統(tǒng)的成本和復(fù)雜度都相應(yīng)提高，使用的波長(zhǎng)數(shù)量越多，載波通道間隔越小，實(shí)現(xiàn)起來(lái)的難度就越大。在實(shí)際應(yīng)用當(dāng)中，往往只需要幾個(gè)波長(zhǎng)信道就可以滿足用戶對(duì)帶寬的需求，這就使得稀疏波分復(fù)用器（cwdm）技術(shù)應(yīng)運(yùn)而生。整個(gè)CWDM系統(tǒng)成本只有DWDM的30%，系統(tǒng)的結(jié)構(gòu)也比DWDM系統(tǒng)簡(jiǎn)單。
