粗波分复用器
Coarse Wavelength Division Multiplex
粗波波分复用器Coarse Wavelength Division Multiplex 是基于薄膜滤波器技术,主要应用在城域网汇聚和接入层,可在短时间建网并开展业务。由于CWDM具有低成本,低功耗,小体积等诸多优点,是一种低价格,高性能的传输解决方案,现已广泛应用于城域网传输。
Coarse Wavelength division multiplexer(CWDM) is based on the membrane filter technique .It
has been mainly used in metropolitan area network convergence and access layer ,you can form a
network and conduct business in a short time. CWDM has the great advantage of low cost、low
power consumption、small size and so on,it becomes a kind of low price and high performance
transmission solution, has been widely applied in the metropolitan area network transmission.
