The dual fiber MUX /
DEMUX board (TFF) launched by D Tech Trading is specially designed for DWDM
network applications with multiple wavelengths. 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.
Application case:
- It is applicable to
4-channel and 8-channel DWDM optical signal MUX and DEMUX in dual fiber
transmission
