# FW6100G4SQ  4X  QSFP28  100G  OTU/OEO  Transponder Card

The 4X QSFP28  100G OTU/OEO Transponder Card is developed by DFT  for optical fiber links. It employs the principle of optical\-electrical optical conversion to regenerate optical signals and convert  them  into  DWDM  standard  wavelength  signals.  When  used  in  conjunction  with  DWDM multiplexers/demultiplexers, it enables wavelength\-division multiplexing transmission. This provides an excellent solution for addressing the challenges of limited optical fiber resources and high fiber line losses in transmission networks.
