Ngaba ukhe wakhalaza kuwe, "Le yinethiwekhi embi," xa uqhagamshelo lwakho lwe-intanethi lucotha? Namhlanje, siza kuthetha ngePassive Optical Network (PON). Ayisiyo inethiwekhi "embi" ocinga ngayo, kodwa usapho olukhulu lwelizwe lomnatha: PON.
1. I-PON, i-"Superhero" ye-Network World
I-PONibhekisela kwinethiwekhi ye-fiber optic esebenzisa i-point-to-multipoint topology kunye ne-optical splitters ukuhambisa idatha ukusuka kwindawo yokuhambisa enye ukuya kwiindawo ezininzi zokugqibela zabasebenzisi. Iqukethe i-terminal optical line (OLT), iyunithi yenethiwekhi ye-optical (ONU), kunye nenethiwekhi yokusabalalisa optical (ODN). I-PON isebenzisa uthungelwano lofikelelo lwamehlo olungenakwenziwa ngokupheleleyo kwaye yiP2MP (iNqaku kwiNqaku eliNinzi) inkqubo yofikelelo yokubona. Inika iingenelo ezinjengokugcina imithombo yefiber, engadingi mandla e-ODN, ukuququzelela ukufikelela kwabasebenzisi, kunye nokuxhasa ukufikelela kwiinkonzo ezininzi. Bubuchwephesha bokufikelela kwifiber optic yebroadband ekhuthazwa ngokusebenzayo ngabaqhubi.
I-PON ifana ne "Ant-Man" yelizwe lothungelwano: icwecwe kodwa inamandla amangalisayo. Isebenzisa i-fiber optical njengendlela yokudlulisa kwaye isasaze imiqondiso ye-optical ukusuka kwi-ofisi ephakathi ukuya kwiindawo ezininzi zokuphela kwabasebenzisi ngokusebenzisa izixhobo ezisebenzayo, ezivumela iinkonzo zokufikelela kwi-broadband ngokukhawuleza, okusebenzayo kunye neendleko eziphantsi.
Khawufane ucinge ukuba umhlaba womnatha une-superhero, i-PON ngokuqinisekileyo iya kuba yi-Superman ephantsi. Ayifuni amandla kwaye "inokubhabha" kwihlabathi le-intanethi, izisa amava e-Intanethi akhawulezayo kumawakawaka amakhaya.
2. Iinzuzo ezingundoqo zePON
Enye ye-PON's "superpowers" kukuhanjiswa kwayo ngesantya sokukhanya. Xa kuthelekiswa nothungelwano locingo lobhedu oluqhelekileyo, i-PON isebenzisa i-fiber optical, ekhokelela kwizantya zothumelo olukhawulezayo.
Khawube nomfanekiso wakho ukhuphela imuvi ekhaya, kwaye ivele kwangoko kwisixhobo sakho njengomlingo. Ngaphaya koko, i-fiber optical iyamelana nokubetha kombane kunye nokuphazamiseka kwe-electromagnetic, kwaye uzinzo lwayo alufani.
3. IGPON & EPON
Amalungu amabini awaziwayo kakhulu kwintsapho yeteknoloji ye-PON yi-GPON kunye ne-EPON.
I-GPON: Amandla oSapho lwePON
GPON, emele i-Gigabit-Capable Passive Optical Network, yindlu yamandla yentsapho ye-PON. Ngokukhawuleza kwe-downlink ukuya kwi-2.5 Gbps kunye nesantya se-uplink se-1.25 Gbps, inikezela ngesantya esiphezulu, idatha ephezulu, ilizwi, kunye neenkonzo zevidiyo kumakhaya kunye namashishini. Yiba nomfanekiso wakho ukhuphela imuvi ekhaya. I-GPON ikuvumela ukuba ufumane ukukhuphela ngokukhawuleza.Ngaphezu koko, iimpawu ze-asymmetric ze-GPON zilungelelaniswa ngakumbi kwimarike yenkonzo yedatha ye-broadband.
I-EPON: Inkwenkwezi eSpeed ye-PON yoSapho
EPON, emfutshane ye-Ethernet Passive Optical Network, yinkwenkwezi yesantya yosapho lwePON. Nge-symmetrical 1.25 Gbps phezulu kunye nesantya esisezantsi, ixhasa ngokugqibeleleyo abasebenzisi abaneemfuno ezinkulu zokulayisha idatha. I-EPON's symmetry iyenza ibe lolona khetho lufanelekileyo kumashishini kunye nabadali bomxholo abaneemfuno ezinkulu zokulayisha.
I-GPON kunye ne-EPON zombini iteknoloji ye-PON, ihluke ngokuyinhloko kwiinkcukacha zobugcisa, amazinga okuhambisa, izakhiwo zesakhelo, kunye neendlela zokufaka i-encapsulation. I-GPON kunye ne-EPON nganye ineenzuzo zabo, kwaye ukhetho luxhomekeke kwiimfuno ezithile zesicelo, uhlahlo lwabiwo-mali lweendleko, kunye nokucwangciswa kwenethiwekhi.
Ngenkqubela phambili yetekhnoloji, iyantlukwano phakathi kwezi zimbini ziyancipha. Ubuchwephesha obutsha, obufana ne-XG-PON (i-10-Gigabit-Capable Passive Optical Network) kunyeXGS-PON(I-10-Gigabit-Capable Symmetric Passive Optical Network), inikezela ngesantya esiphezulu kunye nokusebenza okuphuculweyo.
Izicelo zePON Technology
Itekhnoloji yePON inoluhlu olubanzi lwezicelo:
Ukufikelela kwi-Broadband yasekhaya: Ibonelela ngeenkonzo ze-intanethi ezikhawulezayo kubasebenzisi basekhaya, ukuxhasa ukusasazwa kwevidiyo enenkcazo ephezulu, imidlalo ye-intanethi, kunye nokunye.
Uthungelwano lweShishini: Ukubonelela ngamashishini ngoqhagamshelo lwenethiwekhi oluzinzileyo, ukuxhasa ukuhanjiswa kwedatha enkulu kunye neenkonzo zecomputing yamafu.
I-PON yi "smart butler" onobuqili. Ngenxa yokuba ayisebenzi, iindleko zokuyigcina zicuthwe kakhulu. Abaqhubi akusekho mfuneko yokuba bafake kwaye bagcine izixhobo zombane kumsebenzisi ngamnye, okonga imali eninzi. Ngaphaya koko, ukuphuculwa kwenethiwekhi yePON kulula kakhulu. Akukho komba ifunekayo; ngokulula ukuphucula izixhobo kwindawo ephakathi kuya kuhlaziya yonke inethiwekhi.
Izixeko ezihlakaniphile: Kulwakhiwo lwesixeko esilumkileyo, itekhnoloji ye-PON inokudibanisa izinzwa ezahlukeneyo kunye nezixhobo zokubeka iliso, ivumela uthutho olukrelekrele, ukukhanya okukrelekrele kunye nobunye ubuchwephesha.
