Yintoni umahluko phakathi kwe-OLT kunye ne-ONU?

I-OLT kunye ne-ONU ngokwesiseko zizixhobo ezibini ezibalulekileyo ekufuneka uzazi malunga nefiber. Ezi zixhobo zibalulekile ekudibaniseni ikhaya, imfundo kunye neshishini kwi-intanethi. Funda ukuba ezi zixhobo zisebenzisana njani ukuze uqonde ukuba i-intanethi iza njani kuwe. Ke, uthini umahluko phakathi kwe-OLT kunye nokuCinga amaTides un? 

OLT vs. ONU

I-Optical Line Terminal (OLT) sisixhobo esisodwa esihambisa iimpawu ukusuka kumnikezeli wonxibelelwano lwe-intanethi kubasebenzisi abahlukeneyo. Unokucinga ngayo njengomlawuli wezithuthi onokuthi uncede ukulawula ukuhamba kwedatha kwiindawo zayo zokugqibela, ukuqinisekisa ukuba uya apho kufuneka uhambe khona. Iqinisekisa ukuba i-intanethi inokuba nabasebenzisi abaninzi abaqhagamshelwe ngaxeshanye ngaphandle kokubangela nayiphi na imiba.

Ngokwahlukileyo, i-ONU okanye i-Optical Network Unit yiyo edibanisa wena (kunye nosapho lwakho) kwi-intanethi. Yicinge njenge-bouncer evumela idatha ukusuka kwi-OLT ukuya endlwini yakho. I-ONU yindoda ephakathi phakathi kwezixhobo zakho ezinjengeekhompyuter kunye neetafile ezinxibelelana ne-OLT xa unqwenela ukuqhubeka nokukhangela kwakho okumdaka kwi-intanethi. 

Iimpawu eziphambili kunye neMisebenzi

I-OLT inemisebenzi emininzi ebalulekileyo kunye neempawu ezimvumela ukuba adlale indima enkulu yothungelwano lwefiber. Umsebenzi ophambili kukufumana imiqondiso ye-intanethi kumnikezeli wenkonzo kwaye wabelane ngayo phakathi kwabasebenzisi abaninzi ngexesha. Ubuchwephesha obuxhaswayo: Ixhasa ubuchwephesha obahlukeneyo kubandakanya iGPON, EPON, kunye neXG-PON, zonke ezo zibuchwephesha bokuhambisa i-fiber-optic. I-OLT ayithumeli kuphela idatha, kodwa ikwasebenza njengomphathi wothungelwano. Ibeka iliso kusetyenziso lwe-bandwidth, ukubunjwa kwetrafikhi kunokuthintela ukucotha kwaye incinci yeQoS iya kulawula abasebenzisi ukuqinisekisa ukuba ngamnye unokusebenzisa isabelo sabo esifanelekileyo se-intanethi.

Esinye isixhobo esibalulekileyo kuthungelwano lwefiber yi-ONU. YiNdlu, nayiphi na indlu, okanye indawo yokufikelela kwi-Wi-Fi edibanisa umsebenzisi wokugqibela kwi-intanethi, inokusasazwa kwiindawo ezininzi, njengamakhaya, izikolo, kunye namashishini. IiThink Tides iyunithi yenethiwekhi yamehlo ivumela kwaye iqinisekise ukuba abasebenzisi bafumana ukufikelela okukhuselekileyo kwi-intanethi. Oku kwenza ukuba kuqinisekiswe ugunyaziso lwenethiwekhi olumisela isibonelelo soqhagamshelo, ukuqinisekiswa komsebenzisi ukuqinisekisa ubuni bomntu kunye nofihlo lwedatha ukugcina ukhuseleko lolwazi. 

Yintoni eyahlula iiOLT kwii-ONU?

I-OLT kunye ne-ONU zikhonza imisebenzi eyahlukeneyo kwi-fiber network system, kwaye lo ngumahluko omkhulu phakathi kwabo. OLT (Optical Line Terminal) isixhobo esilawula kwaye sithumela iimpawu ze-intanethi kubasebenzisi abaninzi ngaxeshanye. Ngokuqhelekileyo, ii-OLT zisetyenziswa ngaphakathi kwendawo ephakathi njengendawo yedatha apho ziyakwazi ukuthumela ngokulula iimpawu kwii-ONU ezininzi. Kwelinye icala, i-ONU ibekwe kufutshane nabasebenzisi, njengasemakhaya okanye eziofisini. Umsebenzi wayo ophambili kukudibanisa umsebenzisi ngamnye kwi-intanethi, ukuthatha imiqondiso evela kwi-OLT kwaye emva koko usasaze olo xhulumaniso kwizixhobo zabo. 

Umahluko phakathi kwe-OLT kunye ne-ONU kwiiNethiwekhi zeFayibha

Ukuqonda ngakumbi malunga nendima ye-OLT kunye ne-ONU kuthungelwano lwefiber, funda. I-terminal ye-optical line (OLT) iphatha iifiber zamehlo ezidibanisa abasebenzisi abahlukeneyo. Xa ucinga ngamaTides i-olt fiber ifumana imiqondiso kumboneleli wenkonzo, iwadlulisela kwii-ONU ezininzi. Ezo miqondiso zifakwa kwiYunithi yeNethiwekhi (ONU) eqhagamshela izixhobo zabasebenzisi ekhaya, esikolweni okanye kwishishini.

Masithi umzekelo, xa ufuna ukubukela ividiyo kwi-intanethi, isixhobo sakho sithumela isicelo kwi-ONU. Abafowunelwa be-ONU ye-OLT ngolwazi lwevidiyo. Emva kokuba inolwazi, ibuyisela loo datha kwisixhobo sakho ukuze ukwazi ukusebenzisa ividiyo yakho. Konke oku kuhamba ngokukhawuleza okukhulu, kukuvumela ukuba ungene kwi-intanethi kwaye ubukele iividiyo ngaphandle kokulinda. 

Yeyiphi onokuyikhetha kwiNethiwekhi yakho?

Xa kuqwalaselwa i-fiber network deployment, kufuneka kuqatshelwe ukuba zombini i-OLT kunye ne-ONU ziya kufuneka. Ii-ONU ezininzi zithetha ukuba, uninzi lwabasebenzisi oya kuba nalo. Umzekelo, ukuba uqhagamshela abasebenzisi abambalwa, njengakwindawo ezolileyo, uzakufuna ii-ONU ezimbalwa kuphela. Kwelinye icala, ukuba uqhagamshela uninzi lwabasebenzisi - njengakwisithili seshishini esixakekileyo esinabantu abambalwa suku ngalunye abafikelela kwi-Intanethi (ucinga ukuba bonke baqhagamshelwe ngaxeshanye) - uya kufuna ii-ONU ezininzi ukugcina yonke into. ukuphawula ngaphezulu.

Ukushwankathela, i-OLT kunye ne-ONU ingena phantsi kwezixhobo ezisetyenzisiweyo ezidibeneyo zezixhobo ezidibeneyo ezidibeneyo ngokugcina inkonzo yedatha ekupheleni kokufikelela kwi-fiber networks access and fibre network end-users. I-OLT ifana ne-traffic cop eqondisa idatha phakathi kwemimandla eyahlukeneyo, ngelixa i-ONU ifana ne-bouncer evumela idatha eyenzelwe umsebenzisi oyedwa ukuba aphume kwi-OLT. Zombini ezi zixhobo zisebenza indima ebalulekileyo ekwenzeni i-intanethi isebenziseke kwaye isebenze. Nokuba usungula inethiwekhi yefiber okanye ufuna iimpendulo, Cinga iiTides liqabane lakho elithembekileyo xa kufikwa kuyo yonke into enxulumene nefiber network!
