Emhlabeni wezokuxhumana, ukuthuthukiswa kwe-low water peak (LWP) i-non-dispersion-shifted single-mode fiber kubangele ukuxokozela, futhi ngesizathu esihle. Le fibre ye-optical entsha yakhelwe amasistimu okudlulisela asebenza kubhendi yefrikhwensi egcwele ukusuka ku-1280nm kuya ku-1625nm, futhi inikeza ukusebenza okuthuthuke kakhulu uma kuqhathaniswa ne-optical fiber evamile.
Enye yezinzuzo eziyinhloko zale fibre entsha amandla ayo okugcina ukuhlakazeka okuphansi kubhendi yendabuko engu-1310nm ngenkathi ikhombisa ukulahlekelwa okuncane ebhendini engu-1383nm. Lesi sici esiyingqayizivele sivumela ukusetshenziswa okugcwele kwe-E-band, esukela ku-1360nm kuya ku-1460nm. Ngenxa yalokho, ama-telcos nabaqhubi benethiwekhi banethemba ngomthelela ongaba khona wobuchwepheshe kumasistimu abo.
Umthelela wokuthuthukiswa kwe-LWP non-dispersion shifted single-mode fiber ufinyelela kude. Ngokusebenzisa ngokugcwele i-E-band, le fibre ivula amathuba amasha okwandisa amandla kanye nokusebenza kahle kwezinhlelo zokuxhumana ezibonakalayo. Le ntuthuko iza ngesikhathi esibucayi lapho ingqalasizinda yenethiwekhi ibhekene nemikhawulo yayo njengoba isidingo sokudluliswa kwedatha ngesivinini esikhulu sikhula.
Leli themba lijabulisa kakhulu ezimbonini ezifana nezikhungo zedatha, ezokuxhumana nabahlinzeki bezinsizakalo ze-inthanethi, zonke ezizohlomula emandleni athuthukisiwe ahlinzekwa yile fiber. Ukwengeza, amandla okusebenza okuthuthukisiwe kwesistimu kanye nokunciphisa isignali okuncishisiwe phezu kohlu olubanzi lwamaza wamaza kuyisiphakamiso esiphoqelelayo salabo abahilelekile ekusetshenzisweni kwamanethiwekhi okuxhumana okukhanya.
Njengoba imboni yezokuxhumana iqhubeka nokuthuthuka futhi nesidingo sokudluliswa kwedatha ngesivinini esikhulu sikhuphuka, amathuba okuthuthukiswa kwe-fiber optical fiber enezinga eliphansi lezinga eliphezulu elingahlakazeki-eshintshiwe yemodi eyodwa amele ingqophamlando ebalulekile. Isithembiso samandla okudlulisela akhulisiwe kanye nokusetshenziswa ngokugcwele kwe-E-band kwenza le fibre iguqule umdlalo, ingenise inkathi entsha yokusebenza kahle nekhono ezinhlelweni zokuxhumana ezibonayo. Inkampani yethu futhi izibophezele ekucwaningeni nasekukhiqizeniIsiqongo samanzi aphansi esingahlakazisi i-fiber yemodi eyodwa, uma unentshisekelo enkampanini yethu kanye nemikhiqizo yethu, ungaxhumana nathi.
