Yintoni iGPON Internet?

I-Intanethi ye-GPON yitekhnoloji yokuhanjiswa kwedatha ye-optical ekuvumela ukuba udibanise ababhalisile kwi-Intanethi ngesantya esiphezulu kunye nokuthembeka. Kweli nqaku siza kukuxelela ukuba yintoni i-GPON ye-Intanethi, isebenza njani, yeyiphi inzuzo enayo kunye nendlela yokudibanisa.

Yintoni iGPON Internet?

I-GPON (i-Gigabit Passive Optical Network) yinethiwekhi ye-optical ye-passive esebenzisa i-fibers optical ukuhambisa idatha phakathi kweofisi ephakathi (OLT) kunye nezixhobo zababhalisi (ONT). I-Intanethi yeGPON ibhekisa kumgangatho we-ITU-T G.984, ochaza iiparamitha kunye neempawu zenethiwekhi enjalo.

GPON kwi-intanethi inikeza isantya esiphezulu sokudlulisa idatha - ukuya kwi-2,5 Gbit / s kwicala ukusuka kwi-OLT ukuya kwi-ONT kwaye ukuya kwi-1,25 Gbit / s kwelinye icala. Ukongeza, i-GPON ye-Intanethi ixhasa iintlobo ezahlukeneyo zetrafikhi, njenge-Intanethi, umnxeba, umabonwakude, ukucupha ividiyo kunye nabanye.

Isebenza njani i-Intanethi yeGPON?

I-intanethi ye-GPON isebenza kumgaqo wokwahlula ixesha (TDM) kunye ne-wavelength division (WDM). I-TDM ithetha ukuba idatha evela kubabhalisi abahlukeneyo idluliselwa kwi-fiber optical efanayo ngamaxesha ahlukeneyo, kwaye i-WDM ithetha ukuba idatha evela kwiindidi ezahlukeneyo zetrafikhi ihanjiswa ngaphezu kwamaza ahlukeneyo.

I-Intanethi ye-GPON iqulethe izinto ezintathu eziphambili:

• I-OLT (i-Optical Line Terminal) sisixhobo esisembindini esidibanisa nomnikezeli we-Intanethi kwaye silawula ukuhanjiswa kwedatha phakathi kweefibers ze-optical kunye nezixhobo zokubhalisa.
• I-ONT (i-Optical Network Terminal) sisixhobo somrhumo esidibanisa kwi-fiber optical kunye nokuguqula izibonakaliso ze-optical zibe iimpawu zombane, kwaye zibonelela ngezihlanganisi zokudibanisa izixhobo ezahlukeneyo ezifana nekhompyutheni, ifowuni, i-TV kunye nabanye.
• I-ODN (i-Optical Distribution Network) yinethiwekhi yefiber optical edibanisa i-OLT kunye ne-ONT. I-ODN inokubandakanya amacandelo optical ahlukeneyo afana neziqhekeza, izihlanganisi, iiadaptha, kunye nezinye.

Ngokucwangcisiweyo, i-Intanethi yeGPON inokumelwa ngolu hlobo lulandelayo:

Izinto ezilungileyo zeGPON

Ukuqhagamshela kwi-Intanethi ngeGPON kuneengenelo ezininzi kunezinye iitekhnoloji ezifana neADSL, VDSL, Ethernet okanye DOCSIS. Nazi ezinye zazo:

• Isantya esiphezulu. I-GPON ikuvumela ukuba ufumane isantya se-Intanethi ukuya kuthi ga kwi-2,5 Gbit/s, ephindwe kaninzi kunesantya sezinye iitekhnoloji. Oku kuthetha ukuba unokubukela iividiyo ezinenkcazo ephezulu, udlale imidlalo ye-intanethi, ukhuphele iifayile ezinkulu kwaye usebenzise ezinye izixhobo ze-Intanethi ngaphandle kokulibala okanye ukuphazamiseka.
• Ukuthembeka. I-GPON isebenzisa intambo yokukhanya engaxhomekekanga kukuphazamiseka kwe-electromagnetic, ukubola, ukufudumeza ngokugqithiseleyo okanye ukonakala komatshini. Ukongeza, inethiwekhi ye-passive optical ayinazo izinto ezisebenzayo ezinokungaphumeleli okanye zifune ukutshintshwa. Oku kuqinisekisa ukuzinza kunye nomgangatho wonxibelelwano kuyo nayiphi na imeko.
• Ezoqoqosho. I-GPON ikuvumela ukuba unciphise iindleko zokuxhuma kunye nokugcina inethiwekhi, njengoko ayifuni izixhobo ezongezelelweyo, umbane okanye abasebenzi. Ukongeza, i-GPON ikuvumela ukuba ufumane iinkonzo ezininzi zonxibelelwano ngentambo enye, enciphisa inani leengcingo kunye neziseko kwigumbi.
• Ukuguquguquka. I-GPON ixhasa iiprothokholi ezahlukeneyo kunye nemigangatho yokuhanjiswa kwedatha, njenge-IP, i-ATM, i-Ethernet, i-TDM kunye nabanye. Oku kukuvumela ukuba uqhagamshele naziphi na izixhobo kuthungelwano kwaye usebenzise naziphi na iinkonzo zonxibelelwano, ezinje nge-Intanethi, umabonwakude, umnxeba, ukucupha ividiyo, i-intercom kunye nezinye.

Ukungalungi kweGPON

• I-bandwidth elinganiselwe. Nangona i-GPON ibonelela ngesantya esiphezulu se-Intanethi, ayiqinisekiswanga, kodwa kuxhomekeke kwinani lababhalisi abaqhagamshelwe kwi-splitter enye ye-optical. Ukuba baninzi ababhalisile, i-bandwidth yenethiwekhi iya kwahlulwa phakathi kwabo kwaye isantya se-Intanethi sinokuhla. Ngoko ke, kubalulekile ukukhetha umnikezeli olawula inani lababhalisi kwi-divider kunye nokubonelela nge-bandwidth eyaneleyo kumrhumi ngamnye.
• Ukhuseleko oluphantsi. I-GPON isebenzisa ikhebula elilodwa le-optical ukudlulisa idatha kumnikezeli kubabhalisi abaqhagamshelwe kwi-splitter efanayo. Oku kuthetha ukuba bonke ababhalisi bafumana umqondiso ofanayo, onokubanjwa okanye uguqulwe ngabahlaseli. Ngoko ke, kubalulekile ukukhetha umboneleli osebenzisa iindlela ezahlukeneyo zokufihla kunye neendlela zokuqinisekisa ukukhusela idatha yakho ekufikeleleni okungagunyaziswanga.
• Ixabiso eliphezulu. I-GPON ifuna ukufakelwa kwezixhobo ezizodwa, ezixabisa kakhulu. Oku kusebenza kuzo zombini i-OLT ebekwe kumnikezeli kunye ne-ONT ebekwe kwiflethi yomrhumi. Ngaphezu koko, iindleko zentambo ye-optical nazo ziphezulu kuneendleko zekhebula lobhedu. Ke ngoko, amaxabiso okudibanisa kwi-GPON anokuba phezulu kunokunxibelelana nobunye ubuchwephesha.
