Insinga ya fibreikoranabuhanga, harimoinsinga ya optique y'umuyoboro urekuye, byahinduye uburyo bwo guhuza interineti binyuze mu gutanga umuvuduko n'ukwizera bidasanzwe. Hagati ya 2013 na 2018, inganda zariyongereye ku gipimo cy’umwaka cya11.45%, aho ibiteganyijwe bizagera kuri 12.6% mu 2022.Iterambere ry'ubwiyongeregusaba ko habaho gutinda guke no guhuza ibikoresho nezaigaragaza akamaro ka byombiinsinga ya fiber optique yo mu buryo bumwenainsinga ya fiber optique ifite uburyo bwinshimu gushyiraho ahazaza h'ikoranabuhanga. Byongeye kandi, iterambere ryacamahitamo arimo gutanga umusanzu mu iterambere ry'iri koranabuhanga.
Ibintu by'ingenzi byakunzwe
- Insinga za fibre zihuta cyanekandi zitwara amakuru menshi kurusha ay'umuringa. Ni nziza cyane mu gukoresha interineti muri iki gihe.
- Fibre yihariye idacika intege ituma byoroha kuyishyiraho ahantu hato. Ikora neza ahantu hato.
- Insinga nshya za fibre zibungabunga ibidukikijegukoresha ibikoresho by'icyatsi kibisi kugira ngo bifashe isi. Bishyigikira ikoranabuhanga risukuye.
Ikoranabuhanga rya Fiber Cable rigezweho ubu
Ibyiza by'Insinga za Fiber Ugereranije n'Insinga z'Umuringa
Ikoranabuhanga rya fibre ritanga inyungu zikomeye ugereranyije n'insinga zisanzwe z'umuringa, bigatuma ari ryo hitamo ryiza cyane mu guhuza kwa none. Imwe mu nyungu zigaragara cyane ni ubushobozi bwayo bwo kohereza amakuru mu ntera ndende nta kwangirika kw'ibimenyetso. Bitandukanye n'insinga z'umuringa, zifata igihe kinini cyo gukata, insinga za fibre zigumana imbaraga z'ibimenyetso, bigatuma imikorere yizewe. Byongeye kandi, insinga za fibre zitanga umuyoboro munini w'itumanaho, bigashyigikira icyifuzo gikomeje kwiyongera cy'ibikoresho bikoresha amakuru menshi nko kureba amashusho no gukoresha ikoranabuhanga mu bicu.
Indi nyungu ikomeye iri mu kudahangarwa kwabyo n’imikorere y’amashanyarazi (EMI). Insinga z’umuringa zishobora kwangirika cyane, ibyo bikaba bishobora kubangamira ihererekanya ry’amakuru. Insinga z’icyuma zikoresha urumuri mu kohereza amakuru, bigatuma zidashobora kwangirika nk’uko bigenda. Iyi mikorere ituma habaho itumanaho rihoraho kandi ritekanye, ndetse no mu bidukikije birimo urusaku rwinshi rw’amashanyarazi. Byongeye kandi, insinga z’icyuma ziramba kandi zoroshye, bigabanya imbogamizi zo gushyiraho no kubungabunga.
Ibiranga Gutwara Imiyoboro ya Fiber Igezweho
Imiyoboro ya fibre igezweho igaragazwa n'imikorere yayo igezweho, ibyo bikaba byongera imikorere n'ubwizerwe. Kimwe muri ibyo ni ugukoresha fibre zifite bandwidth nyinshi. Urugero,Fibre ya mikoroni 50 ishyigikira umurambararo wa 500 MHz-km, ijyanye n'ibikenewe mu miyoboro igezweho, mu gihe fibre ya mikoroni 62.5 itanga 160 MHz-km kuri porogaramu za FDDI. Izi ntambwe zituma amakuru yoherezwa vuba kandi neza.
Ikindi kintu gitera imbere ni iterambere ry’imigozi idafata imiterere y’inyuma. Iyi migozi ikomeza gukora neza nubwo yagonze ku mfuruka zityaye, bigatuma iba nziza cyane mu gushyiraho ibintu bigoye. Byongeye kandi, udushya mu gusiga irangi ry’imigozi n’ibikoresho byarushijeho kuramba, bigatuma imikorere yayo iramba.Ibigo nka Dowellbari ku isonga muri izi ntambwe, batanga ibisubizo bigezweho bihuye n'ibyifuzo by'ikoranabuhanga rigezweho.
Icyerekezo cy'insinga za Fiber muri 2025
Fiber yo kubura cyane: Yongera ubushobozi bwo gukoresha amajwi neza
Ikoranabuhanga rya fibre igabanya igihombo kinini riri gushyiraho ibipimo bishya mu mikorere myiza y'amajwi. Mu kugabanya igihombo cy'amajwi y'urumuri, iri vugurura rituma amakuru ashobora gukora intera ndende adasenyuka. Iri terambere rirushaho kunoza cyane uburyo bwo gukoresha amajwiIgipimo cy'urusaku rw'amajwi n'amajwi (OSNR), bitanga itumanaho risobanutse kandi ryizewe. Byongeye kandi, insinga zo gutakaza nke cyane zishyigikira igipimo cyo hejuru cy'amakuru, harimo 100 Gbit/s, 200 Gbit/s, ndetse na 400 Gbit/s, bigatuma ziba nziza kuri porogaramu za interineti yihuta cyane. Kongera ubushobozi bwo kohereza amakuru bigabanya kandi gukenera kongera ibimenyetso, bigabanya ikiguzi cy'imikorere ku batanga serivisi z'itumanaho.
