Amakuru - Umuyoboro wa fibre optique

Itumanaho rya fibre optique ifata urumuri nkitumanaho ryamakuru kugirango bavugane.Irashobora kwanduzwa binyuze muri fibre.Ariko, ntabwo urumuri rwose rwumucyo rukwiriye gushyikirana.Igihombo cyoherejwe kiratandukanye numurongo utandukanye wumucyo.Kugirango ugere ku gihombo gito kandi neza, abahanga bahora bashaka urumuri rukwiye.

850nm Umuyoboro

Mu ntangiriro ya za 1980, abahanga batangiye gucukumbura ikoranabuhanga rya optique ya fibre optique muburyo bufatika.Fibre-moderi fibre nicyo biga cyane cyane.Hamwe na fibre nini nini, fibre-modi fibre irashobora kubona fibre imwe yoherejwe kumatara-muti.850nm itara ryumurongo niryo ryakoreshejwe mbere.

O Waveband

Mu ntangiriro ya za 90, fibre imwe-imwe yatangiye gukoreshwa cyane.

Igishushanyo 1

Abahanga basanze urumuri rwa 1260nm ~ 1360nm rushobora kugera ku kimenyetso gito cyo kugoreka no gutakaza ibimenyetso byatewe no gutatanya binyuze mu bizamini.Nuko rero, bavuze ko urumuri rwitwa O-band na “O” bisobanura “Umwimerere”.Hamwe n'ibigeragezo n'amakosa, abahanga basanze urumuri rufite 1260nm ~ 1625nm narwo ruri ahantu hatakaye kandi ni urumuri rukwiranye no kwanduza fibre.

1260nm ~ 16.

Igishushanyo 2

Abahanga basanze kandi isano iri hagati yo gutakaza kwanduza nuburebure bwumurongo.Irerekana ku buryo bukurikira.

Igishushanyo 3

Itsinda rikoreshwa cyane ni C umurongo (（1530nm ~ 1565nm), bisobanura “bisanzwe”.C band irashobora kugera kubihombo byibuze bikoreshwa cyane kuri MAN, intera ndende, ultra ndende, sisitemu yo mumashanyarazi ya optique na sisitemu ya WDM.

L Waveband （1565nm ~ 1625nm）

L bisobanura “uburebure-burebure”.L umurongo wa interineti ushobora kugera ku gihombo cya kabiri cyo kwanduza kandi ni kimwe mu bintu nyamukuru bihitamo inganda.Niba umurongo wa C udashobora guhaza ibyifuzo byumurongo mugari, Abantu mubisanzwe bazafata L umurongo wuzuzanya.

S Waveband （1460nm ~ 1530nm）

S bisobanura “uburebure-buke”.Ku bijyanye no gutakaza fibre, iba hejuru ya O umurongo.Mubisanzwe bikoreshwa kumurongo wo hasi wa PON.

E Umuyoboro

Nibisanzwe byibuze umurongo wubwoko butanu bwumurongo.E bisobanura "kwaguka" .Nkuko bigaragara ku gishushanyo cya 3, igituba gishobora kugaragara kuri E umurongo.Ibyo ni ukubera ko yakiriwe na OH- biganisha ku gihombo kinini cyo kwanduza, ari nacyo bita impinga y'amazi.

Kera, kubera tekiniki nkeya, amazi yavanze mubirahuri bya fibre optique byatumye igihombo kinini cyogukwirakwiza muri E waveband kandi ntigishobora gukora mubisanzwe.Nyuma yaho, abantu batezimbere tekinoroji yo gukora ibirahuri mugukora ibirahure, kuva icyo gihe, igihombo cyo kwanduza muri E umurongo cyagabanutse ndetse no munsi ya O umurongo.Nyamara, igihombo cyoherejwe cyabaye kuri E umurongo wa optique ya fibre optique washyizeho mbere isobanura ko haracyari imbogamizi kuri E umurongo mugari ukoreshwa mubitumanaho bya fibre optique.
