The dual fiber fixed OADM (optical add-drop multiplexer) card (TFF) launched by Sintai Communication is specially designed for multi-wavelength DWDM network applications. It can multiplex different wavelengths of optical onto one optical fiber or separate multiple optical channels multiplexed on the same optical fiber by wavelength. Based on thin film filter (TFF) technology, it works on ITU grid with 100GHz channel spacing. DWDM wavelength range is 1528nm to 1568nm, and ITU channel wavelength is optional. It has a series of advantages such as low insertion loss and high channel isolation.
