Uyini umgomo wesakhiwo se-wavelength division multiplexing system?

I-Optical wavelength division multiplexing ubuchwepheshe obudlulisa amasiginali we-multi-wavelength optical ku-fibre eyodwa yokubona.Umgomo oyisisekelo uwukuhlanganisa (ama-multiplex) amasignali okubona amaza ahlukene ekugcineni kokudlulisela, amatanise ku-fiber optical efanayo emugqeni wekhebula obonakalayo ukuze adluliselwe, futhi ahlukanise (demultiplex) amasignali okubona obude obuhlanganisiwe ekugcineni kokwamukela. ., futhi kuqhutshekwa kucutshungulwe, isiginali yoqobo iyatholwa futhi ithunyelwe kumatheminali ahlukene.

I-WDM wavelength division multiplexing akuwona umqondo omusha.Ekuqaleni kokubonakala kokuxhumana kwe-fiber optical, abantu baqaphela ukuthi umkhawulokudonsa omkhulu we-fiber optical ungasetshenziselwa ukuhanjiswa kwe-wavelength multiplexing, kodwa ngaphambi kweminyaka yawo-1990, kwakungekho impumelelo enkulu kulobu buchwepheshe.Ukuthuthukiswa okusheshayo Ukusuka ku-155Mbit/s kuya ku-622Mbit/s kuya ku-2.5Gbit/s System izinga le-TDM belilokhu liphindeka kane eminyakeni embalwa edlule Abantu abavamile ukunaka obunye ubuchwepheshe lapho ubuchwepheshe obubodwa buhamba ngokushesha Ngonyaka ka-1995 Isizathu esibalulekile sokushintshashintsha kwezobuchwepheshe. ukuthuthukiswa kohlelo lwe-WDM ukuthi abantu bahlangabezane nezingqinamba kubuchwepheshe be-TDM 10Gbit/s ngaleso sikhathi, futhi amehlo amaningi agxile ekuphindaphindeni nasekusetshenzisweni kwamasignali okubona.Kungaleso sikhathi kuphela lapho uhlelo lwe-WDM lwaba nezinhlelo eziningi ezihlukene emhlabeni jikelele..
