GAOTek DWDM OEO Transponder

GAOTek DWDM OEO transponder is a service access module for optical fiber links.




GAOTek DWDM OEO transponder is a service access module for optical fiber links. It can regenerate 3 R signals for 100 Gbits / s and 25 Gbits / s services with arbitrary rate protocols and can be converted into CWDM or DWDM standard wavelength optical signal. It can be used in optical communication systems such as eCPRI or CPRI or Ethernet with CWDM or DWDM multiplexer or demultiplexer to multiplex multi-service into one fiber, it provides a high-quality solution for solving transmission lines with insufficient fiber resources and high fiber line loss.
