Polarization-maintaining fiber Dense Wavelength Division Multiplexing (DWDM) is a kind of optical fiber data transmission technology, which uses the wavelength of laser to transmit data in the optical fiber in parallel or in serial mode. DWDM is an important component of optical fiber network. It enables data such as e-mail, video, multimedia, data and voice carried by IP protocol, ATM and synchronous optical fiber network/synchronous digital sequence (SONET/SDH) protocol to be transmitted through a unified optical fiber layer.

备注：
*以上指标是不加连接头的参数.(Above specification are for component without connector)
*对于增加连接头的器件，，回损将会降低5dB,消光比也会降低2dB左右.( RL will be 5dB lower and ER will be 2dB lower for component with connector)
*保偏光纤和连接器是慢轴对准。(The PM fiber and connector key are aligned to the slow axis)
