Built on our TFF CWDM 3 Ports technology, the TFF CWDM Module delivers a fully packaged solution for metro access and enterprise networks. This module integrates TFF filters CWDM devices with a ABS box. This module simplifies FTTH node splits and mobile fronthaul wavelength reuse, and it can be widely used in metro optical networks. The CWDM module T&S provides range from two channels to 16 channels with channel central wavelength from 1270nm to 1611nm. Automatic optic alignment technology is adopted, and optical path is epoxy free to ensure excellent performance.
