Nk'umucuruzi w'insinga w'umwuga,ISI IMWEitanga ubwoko bwose bw'ibikoresho fatizo bya optique, harimo na optique ya single-mode yo mu rwego rwo hejuru. Nk'uburyo bw'ibanze bwo kohereza amakuru mu miyoboro ya none y'itumanaho, optique ya single-mode ikoreshwa cyane muri sisitemu y'itumanaho ikora kure kandi yihuta bitewe n'uburyo bwayo bwo kohereza amakuru bwinshi, kugabanuka guke, no kohereza amakuru kure.
Muri iyi nkuru, turasuzuma imiterere y'uburebure bw'umurambararo n'uburyo bwo kohereza amakuru bwa single-modefibre y'urumuriukurikije uburyo ibikoresho bikoreshwa, bitanga ubumenyi bw'ingirakamaro mu guhitamo ibikoresho no gukora insinga.
1. Imiterere y'ibanze ya Fiber Optical yo mu buryo bumwe
Fibre optique yo mu buryo bumwe igizwe n'inkingi n'impande. Imbonerahamwe y'impande iri hejuru y'impande, ituma urumuri rukwirakwira binyuze mu mucyo w'imbere mu gice cy'imbere. Iyi miterere ishyigikira uburyo bumwe bwo gukwirakwiza (uburyo bw'ibanze), ikuraho neza ikwirakwira ry'impande no kunoza ubwiza bw'ihererekanya ry'impande.
Ubusanzwe umurambararo w'ibanze uva kuri mikorometero nyinshi kugeza kuri mikorometero 10, mu gihe umurambararo w'igipfundikizo uba hafi mikorometero 125.
2. Akamaro k'uburebure bw'umuraba
Uburebure bw'amadirishya bugira uruhare runini mu itumanaho rya fibre optique. Amadirishya akoreshwa cyane arimo:
O-band (1260–1360 nm)
Umugozi wa C (1530–1565 nm)
Umugozi wa L (1565–1625 nm)
Muri ubu burebure bw'urumuri, imigozi y'urumuri igaragaza ubushobozi bwo kohereza amakuru neza. Muri yo, C-band ifite ubushobozi bwo kugabanya amakuru (hafi nka 0.2 dB/km), bigatuma iba igikoresho cy'ibanze cyo gukoresha sisitemu ndende z'itumanaho ryihuse kandi rikora intera ndende.
3. Ibiranga Ihererekanyamakuru ry'ingenzi
Igipimo cyo kugabanya ikoreshwa ry'ingufu:
Igipimo cyo kugabanya umuvuduko, gipimirwa muri dB/km, ni igipimo cy'ingenzi gikoreshwa mu gusuzuma igihombo cyo kohereza. Bituruka ahanini ku kwinjiza no gukwirakwira kw'ibintu. Muri C-band, kugabanya umuvuduko bishobora kuba hasi cyane nka 0.2 dB/km, mu gihe biri hejuru gato muri O-band.
Fibre optique yo mu buryo bumwe itangwa na ONE WORLD ikorwa hakoreshejwe ibikoresho bifite ubuziranenge buhanitse n'imikorere ihamye, bigatuma habaho imikorere ihoraho yo kugabanya imikorere hakurikijwe ibipimo ngenderwaho kugira ngo ihererekanywa neza mu ntera ndende.
Ibiranga gukwirakwira:
Gutatana bivuga itandukaniro mu muvuduko w'urumuri ku bunini butandukanye bw'uburebure, bigatuma ibimenyetso birushaho kwaguka. Mu kunoza imiterere y'ibikoresho n'imiterere y'imiterere, insinga zishobora gukorwa zifite imiterere itandukanye yo gutatanya kugira ngo zihuze n'ibikenewe mu itumanaho bitandukanye.
Uburebure bw'Umuraba:
Uburebure bw'uburebure buto ni uburebure bw'uburebure buto aho uburyo bwo kohereza ubutumwa bukoresha uburyo bumwe bushobora gukomeza, ubusanzwe buri hagati ya nm 1260–1300. Munsi y'iki giciro, uburyo bwo hejuru bushobora gukwirakwira, bigira ingaruka ku kudahagarara kw'ibimenyetso. ONE WORLD igenzura cyane uburebure bw'uburebure buto kugira ngo irebe ko imikorere ihamye y'uburyo bumwe mu rwego rw'imikorere yagenwe.
Diameter y'umwanya w'uburyo (MFD):
Umurambararo w'umuyoboro w'amashanyarazi usobanura uko umuyoboro w'amashanyarazi ukwirakwira mu gice cy'imbere cy'umuyoboro w'amashanyarazi ugenda kandi ukagira ingaruka ku mikorere myiza y'umuyoboro w'amashanyarazi n'imikorere yawo. Ibipimo bitandukanye bya MFD birahari kugira ngo bihuze n'ibisabwa bitandukanye mu miterere ya sisitemu no mu gupakira.
4. Kunoza imikorere y'itumanaho
Imikorere yo kohereza ibintu mu buryo bumwe ishobora kunozwa kurushaho binyuze mu kunoza uburyo ibikoresho bisukura no gukora ibintu nka MCVD (Modified Chemical Vapor Deposition). Izi ntambwe zifasha mu kugabanya ubusembwa bw’imyanda n’imiterere y’ibintu, bigatuma habaho kugabanuka guke no gukwirakwira neza kw’ibintu.
ONE WORLD ikomeza gukurikirana iterambere ry’inganda kandi igakorana bya hafi n’abafatanyabikorwa bizewe bo mu nzego zo hejuru kugira ngo batange ibicuruzwa bihamye kandi byujuje ubuziranenge bya fibre optique.
5. Umwanzuro
Ubunini bw'uburebure n'imiterere y'uburyo bwo kohereza amakuru bwa fibre optique imwe bigena mu buryo butaziguye imikorere ya sisitemu z'itumanaho rya optique. Gusobanukirwa neza ibi bipimo by'ingenzi bifasha kunoza imiterere y'urusobe rw'amakuru ya fibre no guhaza icyifuzo gikomeje kwiyongera cyo kohereza amakuru yihuta kandi afite ubushobozi bwo hejuru.
Nk'umufatanyabikorwa wizewe mu bikoresho bya cable, ONE WORLD yiyemeje gutanga fibre optique ihamye kandi yizewe yo gushyigikira imishinga yawe y'itumanaho. Twandikire kugira ngo ubone amakuru arambuye ku bicuruzwa byawe n'ubufasha bwa tekiniki.
