Uxolo malube nani, balandeli abathandekayo, namhlanje siza kuthetha ngalo
Itekhnoloji
Okokuqala, yintoni i-FTTH?
Ngaba uvile nge-FTTH?
Okanye iteknoloji ye-fiber optic yasekhaya
Ngaba ifana neDSL okanye kufutshane nesizukulwana sesine i-4G
Ewe kunjalo, kule okanye leya, kwimigca ezayo siza kuyiphendula le mibuzo kakuhle nangakumbi.
FTTH (ifayibha ekhaya):
Okanye i-fiber optics yasekhaya yitekhnoloji yokuhambisa idatha kunye nolwazi ngaphakathi kweengcingo zeglasi ngesantya esiphezulu kakhulu esilingana nesantya sokukhanya, okuthetha ukuba unokuthelekelela inani elingenasiphelo nelingenamkhawulo wedatha kunye nokuhamba kolwazi.Ngemizuzwana embalwa, ukongeza kulayisho iifayile ezinkulu zeesayizi zegigabyte ngemizuzwana, edlala kwi-Intanethi ngaphandle kokuphazamiseka, ethatha inxaxheba kunxibelelwano lwevidiyo yakho, kunye nokubukela i-IPTV kwi-Intanethi.
FTTH Ifayibha Optical:
Ezona ndlela zilungileyo, zakutshanje kunye nezizinzileyo zonxibelelwano ezikhoyo ngoku ukunxibelelana ne-Intanethi, ukongeza kwisantya sayo esimangalisayo.Yitekhnoloji ezinzileyo engachaphazeleka zizinto zangaphandle ezinje ngokungenelela, umoya, ubushushu bangaphandle, kunye nezinye.
Umahluko kwiilebheli:
FTTN .. Ifayibha kwiNode.
Viber ukuya kwinqanaba lokuqokelela.
FTTC .. Ifayibha kwiNdlela.
Ifayibha ecaleni kwendlela.
FTTB .. Ifayibha kwiSakhiwo.
Viber ukuya kwisakhiwo.
FTTH .. Ifayibha kwiKhaya.
Viber ukuya endlwini.
I-FTTH ithetha ukuba ifayibha ifikelela kwindawo ahlala kuyo umsebenzisi, ngelixa i-FTTB imele ukufikelela kwifayibha kuphela kwisakhiwo hayi kwigumbi lokuhlala. I-FTTC kunye ne-FTTN zikwathetha ukuba ifayibha ifikelela ngaphantsi kwe-300 m eyokuqala nangaphezulu kwe-300 m yeyesibini, oku kwahluka kuyabonakala kumgangatho nakwisantya sonxibelelwano.
Iindawo zenethiwekhi kunye nendlela ezisebenza ngayo:
Izixhobo ezikwisahluli okanye eminqubeni zibizwa ngokuba:
(OLT: Ukupheliswa komgca wokubonisa).
Kwaye inamakhadi aliqela, ikhadi ngalinye linamazibuko abizwa ngokuba:
(PON: Inethiwekhi yePassive Optical).
Idityaniswe kwintambo enye ye-optical ehambisa kunye nokufumana kumaza amabini amade ahlukeneyo. Ukufikelela kwiziphelo ezingama-64 zinikezelwa kwizibuko ngalinye ngokwahlulahlula umsonto ube yimisonto ngokwahlulahlula kwaye iifilitha zixhunyiwe kwisiphelo sendlela:
(ONT: Ukupheliswa kwenethiwekhi)
Khuphela (ukhuphele idatha):
Xa usebenzisa umthetho olandelwayo we-GPON, isantya esidityanisiweyo sisonke yi-2.488 gigabits kubude be-1490 nm. Yonke imida ifumana yonke imiqondiso kwaye yamkela kuphela ulwazi olubhekiswe kwisixhobo sokufumana. Isantya esiphakamileyo esixhaswayo kwisiphelo esinye yi-100Mbps.
Fakela idatha:
Isantya esidibeneyo sisonke yi-1.244 gigabits sisebenzisa ubude be-1310 nm. Isixhobo ngasinye sokuphela sithumela imiqondiso yaso ngokokucwangciswa kunye nokutshintsha kwamaxesha ezibuko, kuthathelwa ingqalelo izinto eziphambili, inqanaba lomgangatho, isantya ekuvunyelwene ngaso, kunye nenqanaba lokuxinana.
Khuphela (Khuphela iVidiyo):
Ubungakanani be-1550 nm busetyenziselwa ukuhambisa ividiyo. Isantya esiphakamileyo esixhaswayo kwisiphelo esinye yi-100Mbps.
Isantya esiphakathi esifunekayo ekhayeni lakho:
Ukuba ubuza malunga nesantya esifanelekileyo se-FTTH sekhaya lakho, isantya esiqhelekileyo esifunwa yindlu ukuya kuthi ga kwi-40 MB, ukuze uxhamle kwiinkqubo zokuncokola ngevidiyo, imidlalo, ukubukela iiTV eziphambili, kunye nokukhuphela iifayile rhoqo nangokuqhubekekayo.
Iinkqubo ze-FTTH:
Kuxhomekeke kwimigaqo efana:
1-GPON.
2-EPON.
3- IBPON.
Kwaye esandula kusetyenziswa yigiga .. GPON
(GPON: IGigabit Passive Optical Network).
Olu lwazi ludluliselwa kwiipakethi ezibizwa ngokuba yi .. GEM
(I-GEM: Imodyuli yokuHanjiswa kweGPON).
Izibonelelo zenethiwekhi ye-FTTH kunye nokuthelekisa kwayo nenethiwekhi yobhedu DSL:
1- Isantya esiphezulu.
2- Ukuchaneka nokucoceka kweempawu.
3- Isantya asinciphi ngomgama owandayo. Oyena mthengi ukude unokufumana isantya esifanayo nesona sikufutshane.
I-4- Ukuguquguquka kweenkonzo kunye nokulula kokuzinikezela.
5- Ukukwazi kwayo ukuxhasa iinkonzo ezizayo.
6- Ukukwazi ukutshintsha amandla kunye nenani lezibuko kumthengi ngokutshintsha isixhobo.
7- Umgama ongaphezulu kwe-8 km ukuya kuthi ga kwi-60 km kwimeko apho isithethe singakhange senziwe isebe.
Isizathu sokusasazeka kancinci kwetekhnoloji ye-FTTH:
Oku kucotha kubangelwa yinto yokuba izixhobo zale teknoloji zibiza kakhulu, ukongeza kubunzima bokugcina kunye nokufaka iifayibha ezibonakalayo ukuba zonakele. Kodwa eyona nto ingumqobo kubunzima bokutshintsha iziseko esele zikhona ngeziseko zophuhliso ezifunekayo kule teknoloji, ukongeza kwinto yokuba umsebenzisi oqhelekileyo akadingi santya siphezulu. Ezi zizathu zibini zenza unxibelelwano ngokwesiko ngocingo lobhedu luyaqhubeka nanamhlanje.
Sinqwenela ukuba wena, abalandeli bethu abaxabisekileyo, ube sempilweni kwaye ube sempilweni
