Overview:
The single fiber MUX / DEMUX board (SBM) launched by Eman Communications 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.
Product Description:
