      Dear all
      can we use mode multiplexing (designed by componenet in multimode section) to longer distance? i mean, when we use more number of mode to multiplex the signal then is it possible to transmit longer distance by fso link?

      Hello there,

      Your question is not quite clear. If I may understand you correctly, since you will use MMF so I guess you need it for short distances but the question is, for How long?

      Generally speaking, and in the scope of short distance MMF, excitation of many nodes doesn’t necessarily produce a significant result due to modal dispersion. Though modes consider as a big advantage that was able to exploit the utilization of wavelength and transmit the data in apparel streams.Howeve, they considered as the biggest disadvantage due to the mode coupling which cause pulse broadening result of distance limitation and increasing BER.

      Suggestion
      ———–
      Use any selective mode excitation techniques along with any type of mode’s compensation either (optical or electronic)

      Regards
