Ese wigeze witotomba uti "Uyu ni umuyoboro mubi cyane," iyo interineti yawe igenda gahoro? Uyu munsi, tugiye kuvuga kuri Passive Optical Network (PON). Si umuyoboro "mubi" utekereza, ahubwo ni umuryango w'intwari ku isi y'umuyoboro: PON.
1. PON, "Intwari ikomeye" y'Isi y'Urusobe rw'Amakuru
PONyerekeza ku muyoboro wa fiber optique ukoresha topology y'ingingo nyinshi n'ibice by'urukiramende kugira ngo byohereze amakuru kuva ku gice kimwe cyo kohereza amakuru kugeza ku mpera z'umukoresha. Igizwe na terminal y'umurongo wa optique (OLT), igice cy'umuyoboro wa optique (ONU), n'umuyoboro w'itumanaho wa optique (ODN). PON ikoresha umuyoboro w'itumanaho wa optique udakora kandi ni sisitemu yo kwinjira mu buryo bwa optique ya P2MP (Point to Multiple Point). Itanga ibyiza nko kubungabunga umutungo wa fibre, kudasaba ingufu kuri ODN, korohereza abakoresha kugera kuri interineti, no gushyigikira kugera kuri serivisi nyinshi. Ni ikoranabuhanga rya internet rikoresha internet rikomeje guterwa inkunga n'abakoresha.
PON ni nk'"Ant-Man" yo mu isi y'itumanaho: ni nto ariko ifite imbaraga zidasanzwe. Ikoresha fibre optique nk'uburyo bwo kohereza amakuru kandi igakwirakwiza ibimenyetso by'urumuri bivuye mu biro bikuru kugeza ku bikoresho byinshi by'abakoresha binyuze mu bikoresho bidakora, bigatuma serivisi zo kugera kuri interineti zihuta cyane, zikora neza kandi zihendutse.
Tekereza iyo isi ya interineti izagira intwari, PON yari kuba Superman idakwiye kwitabwaho cyane. Ntisaba imbaraga kandi ishobora "gukora" mu isi ya interineti, ikazana ubunararibonye bwa interineti bwihuse mu ngo ibihumbi.
2. Ibyiza by'ingenzi bya PON
Imwe mu "mbaraga zikomeye" za PON ni ugukwirakwiza kwayo umuvuduko w'urumuri. Ugereranyije n'imiyoboro gakondo y'umuringa, PON ikoresha fibre optique, bigatuma irushaho kwihuta cyane mu gutwara.
Tekereza gukuramo filime uri mu rugo, maze ihita igaragara kuri terefone yawe nk'ubumaji. Byongeye kandi, fibre y'urumuri irwanya inkuba n'ingufu z'amashanyarazi, kandi ihamye yayo ntagereranywa.
3. GPON na EPON
Abantu babiri bazwi cyane mu muryango w’ikoranabuhanga rya PON ni GPON na EPON.
GPON: Imbaraga z'Umuryango wa PON
GPON, isobanura Gigabit-Capable Passive Optical Network, ni yo sosiyete ikomeye mu muryango wa PON. Ifite umuvuduko wo kugabanya umuvuduko kugeza kuri 2.5 Gbps n'umuvuduko wo kuzamuka wa 1.25 Gbps, itanga serivisi z'amakuru, amajwi, na videwo zihuta cyane mu ngo no mu bigo by'ubucuruzi. Tekereza gukuramo filime mu rugo. GPON igufasha kubona uburyo bwo kuyikuramo ako kanya. Byongeye kandi, imiterere ya GPON idahuje irahuzwa n'isoko rya serivisi z'amakuru ya interineti.
EPON: Inyenyeri y'Umuvuduko w'Umuryango wa PON
EPON, mu magambo ahinnye ya Ethernet Passive Optical Network, ni inyenyeri y'umuvuduko w'umuryango wa PON. Ifite umuvuduko wa 1.25 Gbps uhuza ikoranabuhanga ryo hejuru n'iryo hasi, ifasha cyane abakoresha bakeneye cyane kohereza amakuru. Ubusumbane bwa EPON butuma iba amahitamo meza ku bigo n'abakora ibikubiye ku rubuga bafite ibisabwa byinshi byo kohereza amakuru.
GPON na EPON byombi ni ikoranabuhanga rya PON, bitandukanye cyane cyane mu buryo bwa tekiniki, igipimo cyo kohereza amakuru, imiterere y'amashusho, n'uburyo bwo gufunga amakuru. GPON na EPON buri imwe ifite ibyiza byayo, kandi amahitamo aterwa n'ibisabwa byihariye mu ikoreshwa, ingengo y'imari ikoreshwa, n'igenamigambi ry'umuyoboro w'itumanaho.
Iterambere ry'ikoranabuhanga rigenda rigabanuka. Ikoranabuhanga rishya, nka XG-PON (10-Gigabit-Capable Passive Optical Network) naXGS-PON(Umuyoboro wa 10-Gigabit-Capable Symmetric Passive Optical Network), utanga umuvuduko wo hejuru kandi urushaho kunoza imikorere.
Imikoreshereze y'ikoranabuhanga rya PON
Ikoranabuhanga rya PON rifite uburyo bwinshi bwo gukoresha:
Uburyo bwo gukoresha interineti mu rugo: Butanga serivisi za interineti yihuta ku bakoresha mu rugo, bushyigikira uburyo bwo kureba amashusho mu buryo bworoshye, imikino yo kuri interineti, n'ibindi byinshi.
Imiyoboro y'ibigo: Guha ubucuruzi uburyo buhamye bwo guhuza imiyoboro, bishyigikira serivisi zo kohereza amakuru ku rwego runini no gukoresha serivisi zo gukoresha ikoranabuhanga mu bicu.
PON ni "umucungamutungo w'umuhanga." Kubera ko idakoresha imbaraga nyinshi, ikiguzi cyo kuyisana kiragabanuka cyane. Abayikoresha ntibagikeneye gushyiraho no kubungabunga ibikoresho by'amashanyarazi kuri buri mukoresha, bigatuma bazigama amafaranga menshi. Byongeye kandi, kuvugurura umuyoboro wa PON biroroshye cyane. Nta gucukura bikenewe; kuvugurura ibikoresho gusa ku gice cyo hagati bizavugurura umuyoboro wose.
Imijyi igezweho: Mu bwubatsi bw'imijyi igezweho, ikoranabuhanga rya PON rishobora guhuza ibikoresho bitandukanye byo kugenzura n'ibikoresho byo kugenzura, bigatuma ubwikorezi bw'ubwenge, amatara agezweho, n'andi makoranabuhanga.
