DK Photonics offers a Mini CWDM (compact CWDM) module that provides bandwidth capacity expansion for future network growth in one of the industry’s smallest packages. The compact CWDM modules are based on free space optics technology. It is available in 4-or up to18- channel configurations. It have lower overall insertion loss and better uniformity across the channels. Its compact size and unique carrier tray set it apart, making it easier to deploy in a variety of field situations.
