FTTH. Ubuchwepheshe
Okokuqala, yini i-FTTH?
Futhi uke wezwa nge-FTTH?
Noma ubuchwepheshe be-fiber fiber optic
Ngabe ifana neDSL noma icishe isizukulwane sesine i-4G
Yebo, ngalokhu noma lokho, emigqeni ezayo sizophendula le mibuzo kahle futhi ngokuningiliziwe.
I-FTTH (i-fiber ekhaya):
Noma i-home fiber optics ubuchwepheshe bokudlulisa imininingwane nolwazi ngaphakathi kwezintambo zengilazi ngejubane eliphakeme kakhulu elilingana nejubane lokukhanya, okusho ukuthi ungacabanga inani elingenamkhawulo nelingenamkhawulo lokugeleza kwedatha nolwazi. Ngemizuzwana embalwa kakhulu, ngaphezu kokulayisha amafayela amakhulu osayizi be-gigabyte ngemizuzwana, edlala ku-inthanethi ngaphandle kokuphazamiseka, ebamba iqhaza ngokuxhumeka kwevidiyo yakho, nokubuka i-IPTV nge-Intanethi.
FTTH Fibre Optical:
Izindlela zokuxhumana ezihamba phambili, zakamuva futhi ezizinzile njengamanje zokuxhumana ne-Inthanethi, ngaphezu kwejubane layo elimnandi. Ubuchwepheshe obuzinzile obungathintwa izinto zangaphandle njengokuphazamiseka, umoya, ukushisa kwangaphandle, nokunye.
Umehluko kumalebula:
FTTN .. Fibre kuNode.
Viber kuze kube seqophelweni lokuqoqwa.
FTTC .. I-Fibre Kunqenqema.
I-Fibre endleleni yomgwaqo.
FTTB .. I-Fibre eya Esakhiweni.
Viber kuze kube esakhiweni.
FTTH .. Intambo Ekhaya.
Viber phezulu endlini.
I-FTTH isho ukuthi i-fiber ifinyelela lapho kuhlala khona umsebenzisi, kuyilapho i-FTTB imelela ukufinyelela kwefayibha kuphela esakhiweni hhayi efulethini noma endaweni yokuhlala. I-FTTC ne-FTTN futhi kusho ukuthi i-fiber ifinyelela ngaphansi kwamamitha angama-300 kweyokuqala nangaphezulu kwamamitha angama-300 okwesibili, lokhu kwehlukahluka, kunjalo, kukhonjiswa kukhwalithi nesivinini sokuxhuma.
Izingxenye zenethiwekhi nokuthi zisebenza kanjani:
Imishini esehlukweni noma emadokodweni ibizwa ngokuthi:
(OLT: Optical Line Termination).
Futhi inamakhadi amaningi, ikhadi ngalinye liqukethe izimbobo eziningi ezibizwa ngokuthi:
(I-PON: IPassive Optical Network).
Ixhunywe entanjeni eyodwa ebonakalayo edlulisa futhi yamukele ngamaza amabili ehlukene. Kufika amatheminali afika kuma-64 ethekwini ngalinye ngokuhlukanisa intambo ibe yimicu ngesihlukanisi futhi imicu ixhunywe esikhumulweni:
(I-ONT: Ukunqanyulwa kwenethiwekhi ye-optical).
Landa (Landa idatha):
Lapho usebenzisa umthetho olandelwayo we-GPON, isivinini esiphelele esihlanganisiwe ngama-gigabits angu-2.488 kubude be-1490 nm. Yonke imingcele ithola zonke izimpawu futhi yamukela kuphela imininingwane ebhekiswe kudivayisi etholwayo. Isivinini esiphezulu esisekelwa ukuphela okukodwa yi-100Mbps.
Faka idatha:
Ijubane eliphelele elihlanganisiwe ngama-gigabits angu-1.244 kusetshenziswa ubude be-1310 nm. Idivayisi ngayinye yokugcina ithumela amasiginali ayo ngezikhathi zayo ezihleliwe nezishintsha njalo zetheku, kucatshangelwa okubalulekile, izinga lekhwalithi, isivinini okuvunyelwene ngaso, nezinga lokucinana.
Landa (Landa ividiyo):
Ububanzi be-1550 nm busetshenziselwa ukudluliswa kwevidiyo. Isivinini esiphezulu esisekelwa ukuphela okukodwa yi-100Mbps.
Ijubane elijwayelekile olidingayo ekhaya lakho:
Uma ubuza ngejubane le-FTTH elifanele lekhaya lakho, isivinini esimaphakathi esidingekayo endlini sifinyelela ku-40 MB, ukuze uzuze ezinhlelweni zokuxoxa ngevidiyo, imidlalo, ubuke ama-TV athuthukile, futhi ulande amafayela njalo nangokuqhubekayo.
Izivumelwano ze-FTTH:
Kuya ngemithetho efana nale:
1 - GPON.
2-EPON.
3- iBPON.
Futhi esanda kusetshenziswa yi-giga .. GPON
(I-GPON: IGigabit Passive Optical Network).
Imininingwane idluliselwa ngamaphakethe abizwa ngokuthi yi .. GEM
(I-GEM: I-GPON Encapsulation Module).
Izinzuzo zenethiwekhi ye-FTTH nokuqhathaniswa kwayo nenethiwekhi yethusi i-DSL:
1- Ijubane eliphezulu.
2- Ukunemba nokuhlanzeka kwezimpawu.
3- Ijubane alinciphi ngokwanda kwebanga. Ikhasimende elikude kakhulu lingathola ijubane elifanayo nelamakhasimende aseduze.
4- Ukuguquguquka kwezinsizakalo kanye nokulula kokuzinikela.
5- Ikhono layo lokuxhasa izinsizakalo zesikhathi esizayo.
6- Ikhono lokushintsha amandla nenombolo yamachweba ekhasimende ngokushintsha idivayisi.
7- Ibanga elingaphezu kwamakhilomitha ayi-8 futhi lifike kuma-60 km uma kwenzeka ukuthi isiko lingahlanganisiwe.
Isizathu sokusabalala kancane kobuchwepheshe be-FTTH:
Lokhu kuhamba kancane kungenxa yokuthi imishini yalobu buchwepheshe ibiza kakhulu, ngaphezu kobunzima bokugcina nokufaka imicu ye-optical uma ilimele. Kepha isithiyo esikhulu ubunzima bokushintsha ingqalasizinda ekhona nengqalasizinda edingekayo kulobu buchwepheshe, ngaphezu kweqiniso lokuthi umsebenzisi ojwayelekile akadingi isivinini esikhulu. Lezi zizathu ezimbili zenza ukuxhumana kwendabuko ngocingo lwethusi kuyaqhubeka kuze kube namuhla.
