北极光电的密集波分复用器（DWDM）基于TFF（薄膜滤波器）平台，具有低插损、高隔离度、超热稳定性和优异的可靠性。器件符合Telcordia GR-1221/1209-CORE标准，因此可用于电信网络系统中的波长管理。北极光电可以提供定制的设计，以满足特殊的功能应用。
北极光电的双工DWDM MUX&DEMUX模块设计用于基于TFF技术在两条光纤上组合/分离多个DWDM信号。我们可以提供完整的配置，如2，4，8，16，多达88个通道。 北极光电还可以提供定制设计，以适应现有1310nm和1550nm设备的CWDM升级端口、DWDM升级端口、监视器端口、双向com端口TX/RX、1310nm和1550nm宽带端口的选择。
CWDM is a low cost WDM transmission technology for the metropolitan area network access layer. In principle, CWDM uses optical multiplexer to transmit optical signals of different wavelengths to a single optical fiber. At the receiving end of the link, the mixed signal in the optical fiber is decomposed to different wavelengths with the aid of optical demultiplexer, and connected to the corresponding receiving devices.
