Uphuculo lufuna ukuvavanya amandla akhoyo kunye neenjongo zexesha elizayo. Ukuze kuncitshiswe ukuphazamiseka kangangoko kunokwenzeka, ukuphunyezwa ngokwezigaba kubalulekile.

Umzekelo, ukutshintsha i-multimode fiber nge-single-mode fiber kwiindawo zedatha yindlela ekrelekrele yokuphucula ukusebenza ngelixa uqinisekisa ikamva ukuze uhlale uphambili kunemfuno.

Ukuziqhelanisa neeTekhnoloji eziNtsha

Ukuhlala unolwazi ngezinto ezintsha zamva nje ngefayibha kwandisa ukusebenza kakuhle kunye nomthamo. Imfundo eqhubekayo inceda amanethiwekhi ukuba asebenzise ubuchwepheshe obuphambili kuquka ukwahlulahlula ubude be-wavelength ukuze afikelele ekukhuleni okukhulu.

Isiphelo

Ngokwazi umahluko phakathi kwe-single-mode kunye ne-multimode fiber, uya kuxhotyiswa ngcono ukwenza izigqibo ezikrelekrele ngakumbi malunga noko kufunwa yinethiwekhi yakho. I-single-mode fiber iyasebenza kakhulu ekuqhagamshelweni kwimigama emide kunye neekhonkco ezikhawulezayo nezinomthamo ophezulu, ngelixa i-multimode fiber ifanelekile ngakumbi kwimigama emifutshane kunye neendawo ezijonga uhlahlo lwabiwo-mali. Uhlobo ngalunye luneenzuzo zalo ezahlukeneyo. Khetha uhlobo oluza kusebenzela iimfuno ezizodwa zeprojekthi yakho - ukusuka kuhlahlo lwabiwo-mali, ukuya ekukhuleni, ukuya kwiinjongo zokusebenza.

Nokuba yeyiphi na indlela inika iimpendulo ezithembekileyo nezilungele ikamva kwiinethiwekhi zanamhlanje. Ukukhetha eyona ifanelekileyo kukuvumela ukuba usebenze kakuhle kwaye unciphise isidingo sokuphucula okubizayo. Ukuqhuba iziko ledatha lenkampani, ukwenza inethiwekhi yekhampasi yeshishini ibe yeyanamhlanje okanye ukufaka iziseko zophuhliso ukuze kuhlangatyezwane namathuba amatsha eshishini? Iziseko zophuhliso ezisemgangathweni Ifayibha efanelekileyo inokuchaphazela kakhulu nganye kwezi meko—ngendlela eyakhayo! Ukuze ufumane iziphumo ezilungileyo, khetha ngokufanelekileyo oko ujonge ukukufezekisa kunye nobungakanani benethiwekhi yakho.

 

Imibuzo ebuzwa qho

Yintoni umahluko omkhulu phakathi kwefayibha yemowudi enye kunye nefayibha yemowudi eninzi?

Umahluko omkhulu bubungakanani be-core. I-single-mode fiber inombindi omncinci (malunga ne-8-10 microns), ivumela imo yokukhanya enye, ngelixa i-multimode fiber inombindi omkhulu (50-62.5 microns) kwiimowudi ezininzi zokukhanya. Oku kuchaphazela kakhulu umgama wazo kunye nobuchule be-bandwidth.
