Kuva mu mpera z'imyaka ya za 1980, itumanaho rya fibre-optique ryagiye rihinduka kuva mu burebure bugufi kugera ku burebure burebure, kuva kuri fibre ya multimode yerekeza kuri fibre imwe.Kugeza ubu, fibre imwe-imwe ikoreshwa cyane mumurongo wigihugu wa kabili hamwe numuyoboro wintara.Fibre ya Multimode igarukira gusa kuri LAN zimwe na zimwe zifite umuvuduko muke. Muri iki gihe, fibre abantu bavuga yerekeza kuri fibre imwe.Ubwoko bumwe bwa fibre ifite ibyiza byo gutakaza bike, umurongo mugari, kuzamura byoroshye no kwaguka, hamwe nigiciro gito, kandi ikoreshwa cyane.
Mugihe imibereho yabantu ikeneye gutera imbere kurushaho, interineti iba igice cyingenzi cyubuzima.Mu rwego rwo kubahiriza iterambere ryigihe cyamakuru, tekinoroji ya wiring hamwe nibicuruzwa bihora bivugururwa, cyane cyane ubushakashatsi bunini nogutezimbere insinga za fibre optique .Hariho ubwoko bwinshi bwa fibre optique ya fibre optique yubwoko butandukanye kandi ikoreshwa kumasoko.Nigute ushobora guhitamo ubwoko bufatika imbere ya fibre optique?Nigute ushobora guhitamo ibicuruzwa byiza bya fibre optique?
Ibyiciro byingenzi bya fibre optique
Ukurikije uburyo bwo guhererekanya ibyiciro, fibre optique ifite ubwoko bubiri bwa fibre fibre na fibre imwe.Fibre ya fibre irashobora kohereza uburyo bwinshi, mugihe fibre yuburyo bumwe ishobora kohereza gusa uburyo bumwe kumurongo wogukora.Fibre ikoreshwa cyane ni 50 / 125m na 62.5 / 125m.Dimetero yibanze ya fibre yuburyo bumwe mubisanzwe ni 9/125 m. Fibre ya Multimode-intangiriro ni ndende (50 cyangwa 62.5m).Kubera ko geometrie ya fibre (cyane cyane intangiriro ya diameter d1) nini cyane kuruta uburebure bwumucyo (hafi micron 1), hariho fibre nyinshi cyangwa amagana.Uburyo bwo kwamamaza.Mu gihe kimwe, kubera gutatanya kwinshi hagati yuburyo, inshuro zoherejwe ni nke, kandi kwiyongera hamwe nintera birakomeye. Ukurikije ibimenyetso byavuzwe haruguru, fibre optique ikoreshwa cyane mumiyoboro ifite umuvuduko muke wo kwanduza. kandi ugereranije mugufi intera yoherejwe, nkurusobe rwakarere.Imiyoboro nkiyi isanzwe ifite imitwe myinshi, ingingo nyinshi, kugoreka kwinshi, no guhuza hamwe.Umubare wibigize, umubare wibikoresho bikora bikoreshwa kuri fibre yuburebure, nibindi, gukoresha fibre fibre irashobora kugabanya ibiciro byurusobe.
Fibre imwe-fibre ifite intoki ntoya (muri rusange hafi m 9) kandi irashobora kohereza gusa uburyo bumwe bwurumuri.Nuko rero, gutandukana hagati yuburyo ni bito cyane, bikwiranye n’itumanaho rya kure, ariko haracyari ibintu byo gutatanya ibintu no gukwirakwiza umurongo wa waveguide, bityo fibre imwe-fibre isabwa cyane kubugari bwikigereranyo no gutuza kwumucyo utanga urumuri, ni ukuvuga, ubugari bwikigereranyo bugomba kuba bugufi, kandi ituze rigomba kuba ryiza. Fibre imwe-imwe ikoreshwa cyane mumirongo ifite intera ndende kandi ugereranije umuvuduko mwinshi wohereza, nkurugero rurerure rwohereza imiyoboro, kubaka imiyoboro yumujyi wa metropolitani, nibindi. Imiyoboro ya FTTx na HFC iriho ubu ni fibre imwe gusa.
Itandukaniro riri hagati yuburyo bumwe bwa fibre transibiver na multimode fibre transcevers
Fibre optique transceiver nigikoresho cyohereza imiyoboro ya Ethernet ihinduranya ibimenyetso byamashanyarazi na optique ya Ethernet, hamwe na fibre optique yohereza amakuru kurubuga rushyirwa mubice byinshi bya fibre hamwe na fibre yuburyo bumwe.Kuvana kumurongo, kuko fibre ya multimode idashobora kuba yandikiwe intera ndende, irashobora gukoreshwa gusa muguhuza imbere mumazu no hagati yinyubako.Ariko, kubera ko fibre ya multimode hamwe na fibre transceiver ijyanye nigiciro gito, iracyari murwego runaka. Shaka porogaramu.Amashuri menshi nayo akoresha fibre fibre iyo yubatse umuyoboro wikigo imbere.
Hamwe niterambere ryikoranabuhanga, fibre-moderi imwe yatangiye kwinjira mubikorwa birebire byo guhuza imiyoboro (kuva kuri kilometero nkeya kugera kuri kilometero zirenga ijana), kandi umuvuduko witerambere urihuta cyane, mumyaka mike, kuva murwego rwohejuru rushyirwa mubikorwa ingo zabantu basanzwe, Kurugero, ingo nyinshi ubu zikoresha transiteri ya optique (ibyo bita uburyo bwa FTTH, fibre-to-home) iyo bafunguye umuyoboro.Imikoreshereze ya optique ya transitike yabaye uburyo busanzwe bwa serivisi zongerewe agaciro kubitangaza na tereviziyo.
Ukoresheje fibre optique ihindura imiyoboro, ibyiza ntabwo bihamye gusa, ariko nibindi nibindi?Ngiyo umuvuduko!100M yuzuye duplex, niyo yihuta kurenza 100 duplex yuzuye: 1000M yuzuye duplex.
Yagura intera yohereza imiyoboro ntarengwa kuva 100M ikarenga 100KM kubireba byombi, bishobora kumenya byoroshye guhuza imiyoboro ya seriveri yububiko, gusubiramo, hub, terminal na terminal.Mugihe duhitamo fibre optique, tuzashimangira gusobanukirwa fibre optique, kumenyekanisha ubumenyi bujyanye, no guhitamo fibre ikora neza binyuze mubitekerezo byuzuye.
