Mini CWDM (compact CWDM) modules use one of the smallest packages in the industry to provide bandwidth capacity expansion for future network growth. The compact CWDM module is based on free-space optical technology. It is available in 4-channel or up to 18-channel configurations. It has lower overall insertion loss and better uniformity between channels. Its compact size and unique tray design set it apart, making it easier to install in a variety of field situations.
