The 48-channel passive MUX / DEMUX (MUX48) launched by D Tech Trading is mainly used in DWDM wavelength division system to complete the multiplexing or demultiplexing function of 48 optical wavelengths in the C-band range. It can multiplex different optical wavelengths to one optical fiber or separate multiple optical channels multiplexed in the same optical fiber by wavelength. Based on the waveguide grating technology on silicon substrate, it adopts a unique heat free packaging design, which can achieve accurate channel coupling, low insertion loss, high channel isolation and high stability. It is suitable for 48 wave high-capacity DWDM system.

Application case:

Suitable for multiplexing and demultiplexing 48 channels of DWDM optical signals in C-band
