根据《YD/T5166-2009本地网光缆波分复用传输系统工程设计规范》,本地WDM传输系统采用的技术包括DWDM和CWDM,其中CWDM传输系统的光通道数量可分为:()A、4通道B、8通道C、16通道D、32通道
在中兴DWDM系统中,复位NCP不会影响业务光通道,理由如下()。A、主光通道业务和监控通道在DWDM的独立设计B、WDM系统的业务通道目前产品没有使用光交叉C、在WDM系统中NCP的角色只是对业务光通道进行监控和数据采集,不能对业务光通道进行任何操作D、由于WDM设备上各单板保留有相应的数据,复位NCP板不影响其他单板的数据,所以业务光通道不受影响
下面关于CWDM与DWDM说法中哪个是错误的()A、CWDM的光纤衰耗平坦度低于DWDMB、CWDM的无电中继传输距离小于DWDMC、CWDM的单波最高传输速率为2.5G,低于DWDMD、CWDM的通道间隔小于DWDM
