Dual Fiber Fixed OADM Card(TFF) are used for DCI Box
Optical division multiplexing boards are designed for multi-wavelength DWDM network applications and can be used to redistribute light of different wavelengths onto a single fiber or to separate multiple optical channels multiplexed in the same fiber by wavelength. It is based on thin film filter technology, working in the ITU grid of 100GHz channel interval, DWDM wavelength range of 1528nm to 1568nm, ITU channel wavelength is optional; It has a series of advantages such as low insertion loss and high channel isolation.
