Bitewe n’iterambere ryihuse ry’ikoranabuhanga ry’ubuhanga bw’ubukorano (AI), icyifuzo cy’ubushobozi bwo gutunganya amakuru no gutumanaho cyageze ku rugero rudasanzwe. Cyane cyane mu nzego nka big data analysis, deep learning, na cloud computing, sisitemu z’itumanaho zirushaho kuba nyinshi mu gukenera umuvuduko mwinshi na bandwidth yo hejuru. Fibre isanzwe ya single-mode (SMF) igizweho ingaruka n’umupaka wa Shannon utari umurongo, kandi ubushobozi bwayo bwo kohereza amakuru buzagera ku mupaka wayo wo hejuru. Ikoranabuhanga ryo kohereza amakuru rya Spatial Division Multiplexing (SDM), rihagarariwe na fibre nyinshi (MCF), ryakoreshejwe cyane mu miyoboro yo kohereza amakuru ikora kure n’imiyoboro migufi yo kohereza amakuru, binongera cyane ubushobozi bwo kohereza amakuru muri rusange.
Imigozi myinshi y’urumuri inyura mu nzitizi z’imigozi gakondo y’uburyo bumwe binyuze mu gushyiramo imigozi myinshi yigenga y’urumuri mu mugozi umwe, bikongera cyane ubushobozi bwo kohereza amakuru. Umugozi usanzwe w’imigozi myinshi ushobora kuba ufite imigozi ine kugeza ku munani y’imigozi imwe ikwirakwijwe neza mu gipangu kirinda gifite umurambararo wa 125um, bikazamura cyane ubushobozi bwose bwa bandwidth nta kongera umurambararo w’inyuma, bigatanga igisubizo cyiza cyo guhaza izamuka rikomeye ry’ibikenewe mu itumanaho mu bwenge bw’ubukorano.
Gukoresha imiyoboro y'amashanyarazi ifite imiterere myinshi bisaba gukemura ibibazo bitandukanye nko guhuza imiyoboro ifite imiterere myinshi n'isano iri hagati y'imiyoboro ifite imiterere myinshi n'imiyoboro gakondo. Ni ngombwa guteza imbere ibikoresho bifitanye isano n'ibice byayo nka MCF fibre connectors, ibikoresho bitanga umufana n'umufana kugira ngo MCF-SCF ihindurwe, no gusuzuma uburyo ihura n'ikoranabuhanga risanzweho n'irikoreshwa mu bucuruzi.
Igikoresho cyo gushyiramo/gusohora umufana w’ingufu nyinshi
Ni gute wahuza imiyoboro ya optique ifite core nyinshi n'imiyoboro gakondo ya optique imwe? Ibikoresho bya FIFO (Fiber in and Fan Out) ni ingenzi mu kugera ku guhuza neza hagati y'imiyoboro ya optique ifite core nyinshi n'imiyoboro isanzwe ya optique imwe. Kuri ubu, hari ikoranabuhanga ritandukanye ryo gushyira mu bikorwa ibikoresho bya optique bifite core nyinshi: ikoranabuhanga rya "fused tapered", uburyo bwa "bundle fiber bundle", ikoranabuhanga rya 3D waveguide, n'ikoranabuhanga rya "space optics". Ubu buryo bwose bufite inyungu zabwo kandi bukwiriye ikoreshwa mu bihe bitandukanye.
Igihuza cya fiber optique cya MCF cy'imirongo myinshi
Ikibazo cyo guhuza imiyoboro y'amashanyarazi ifite inkingi nyinshi n'imiyoboro imwe y'amashanyarazi cyarakemutse, ariko isano iri hagati y'imiyoboro y'amashanyarazi ifite inkingi nyinshi iracyakeneye gukemurwa. Kuri ubu, imiyoboro y'amashanyarazi ifite inkingi nyinshi ihuzwa ahanini no guhuza imiyoboro, ariko ubu buryo bufite imbogamizi zimwe na zimwe, nko kugorana cyane mu bwubatsi no kubungabunga mu cyiciro cya nyuma. Kuri ubu, nta gipimo rusange cyo gukora imiyoboro y'amashanyarazi ifite inkingi nyinshi. Buri ruganda rukora imiyoboro y'amashanyarazi ifite inkingi nyinshi zitandukanye, ingano y'inkingi, intera iri hagati y'inkingi, nibindi, ibyo byongera ku buryo butagaragara ingorane zo guhuza imiyoboro y'amashanyarazi ifite inkingi nyinshi.
Module ya MCF Hybrid ifite fiber nyinshi (ikoreshwa muri sisitemu ya EDFA optique amplifier)
Muri sisitemu yo kohereza amakuru mu buryo bwa Space Division Multiplexing (SDM), urufunguzo rwo kugera ku buryo bwo kohereza amakuru bufite ubushobozi bwo hejuru, umuvuduko mwinshi, no kure ni ukwishyura ibura ry'ibimenyetso mu migozi y'urumuri, kandi amplifiers z'urumuri ni ingenzi muri iki gikorwa. Nk'imbaraga z'ingenzi mu ikoreshwa ry'ikoranabuhanga rya SDM, imikorere ya amplifiers za SDM igena mu buryo butaziguye ubushobozi bwa sisitemu yose. Muri zo, amplifiers za multi-core erbium-doped fiber amplifier (MC-EFA) zabaye ingenzi cyane muri sisitemu yo kohereza amakuru ya SDM.
Sisitemu isanzwe ya EDFA igizwe ahanini n'ibice by'ingenzi nka fibre ya erbium-doped (EDF), pompe light source, coupler, isolator, na optique filter. Muri sisitemu ya MC-EFA, kugira ngo habeho ihinduranya rikora neza hagati ya fibre nyinshi (MCF) na single core fibre (SCF), sisitemu ikunze gushyiramo ibikoresho bya Fan in/Fan out (FIFO). Igisubizo cya fibre nyinshi cya EDFA cyitezweho guhuza mu buryo butaziguye imikorere ya MCF-SCF mu bice by'ingenzi bifitanye isano na optique (nk'urugero 980/1550 WDM, gain flattening filter GFF), bityo byoroshya imiterere ya sisitemu no kunoza imikorere muri rusange.
Bitewe n’iterambere rihoraho ry’ikoranabuhanga rya SDM, ibice bya MCF Hybrid bizatanga ibisubizo byiza kandi bidafite igihombo kinini ku buryo bw’ejo hazaza bw’itumanaho ry’amatara rifite ubushobozi bwo hejuru.
Muri uru rwego, HYC yateguye imiyoboro ya MCF fiber optic yagenewe by'umwihariko imiyoboro ya fiber optic ifite inkingi nyinshi, ifite amoko atatu y'imiyoboro: LC type, FC type, na MC type. Imiyoboro ya fiber optic ya LC type na FC type MCF multi-core yahinduwe igice kandi ikorwa hashingiwe ku miyoboro gakondo ya LC/FC, inoza imikorere yo gushyiramo no kubika, inoza uburyo bwo gusya, igenzura ko hagira impinduka nke mu gutakaza insertion nyuma yo guhuza inshuro nyinshi, kandi igasimbuza inzira ihenze yo guhuza fusion kugira ngo yorohereze ikoreshwa. Byongeye kandi, Yiyuantong yanakoze umuyoboro wa MC wihariye, ufite ingano ntoya ugereranyije n'imiyoboro gakondo kandi ushobora gushyirwa ahantu hanini cyane.
