The single fiber MUX /
DEMUX board (SBM) 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. The
wavelength of the ITU channel is optional. It supports serial connection of
EDFA for single fiber bidirectional long-distance transmission with built in
OSC monitoring channel.
Application case:
- It is applicable to 4-channel and 8-channel DWDM
optical signal MUX and DEMUX in single fiber transmission
