PWDM-T155 OR 1310/1490用于光模块的封装,可实现1550,1490/1310两通信窗光信号的合波(复用)与分波(解复用),使单根光纤传输容量倍增,还可实现单纤双向通信,广泛应用于光纤网络升级、扩容或引入综合新业务(广播电视、电信、互联网三网合一PON+EOC)等方面。
PWDM-T1550 OR 1310/1490 is used for dimension of the module which can achieve the multiplexing and demultiplexing of two communication Window of 1550,1490 or 1310 wave signal that makes the makes the capacity doubles of single fiber and can achieve transferring in both directions on one fiber. It is wildly used in upgrading of optical network, enlarge capacity and lead in new business such as radio and television,Telecom,Internet and PON plus EOC.
