Inshuro nziza hamwe na optique yohereza?

Nkuko tubizi, kuva mu myaka ya za 90, tekinoroji ya WDM yakoreshejwe mu makimbirane maremare ya fibre-optic yo mu magana cyangwa n'ibihumbi. Ku turere twinshi tw'igihugu, ibikorwa remezo bya fibre ni umutungo wacyo bihenze, mugihe ikiguzi cyibigizemo ibice bigufi.
Ariko, hamwe no guturika kw'ibiciro by'ibipimo nka 5g, tekinoroji ya WDM iragenda irushaho kuba ihuza rigufi ryose, ryoherezwa mu gitabo kinini kandi kitoroshye ku nteko za Transcei.

Kugeza ubu, iyi miyoboro iracyashingira ku bihumbi hamwe na fibre imwe ya optique itangwa muburyo bwo kugabana umwanya muto.

Ariko, mugihe kizaza kibanziriza, igitekerezo cyo guhinduranya ibintu bisanzwe bizagera ku mbibi zayo, kandi zigomba kuzuzwa na fibrelusliswita zamakuru muri buri fibre kugirango ukomeze rwiyongera mubiciro byamakuru. Ibi birashobora gukingura umwanya mushya wo gusaba tekinoroji ya WDM, aho bikabije mubijyanye numubare wimiyoboro hamwe nigipimo cyamakuru ni ngombwa.

Ni muri urwo rwego,Ifishi ya Optique Compleator (FCG)Huza inshingano zingenzi nkisoko yoroshye, ikosowe, ikosorwa, ihagaze neza zirashobora gutanga umubare munini wabatwara neza. Mubyongeyeho, inyungu ikomeye cyane yumurongo wa optique ni uko imirongo yimyenda yibasiwe niminota imwe, bityo igasabwa kugenzura imiyoboro iringaniye kandi wirinde kugenzura imiyoboro iringaniye kandi wirinde kugenzura umurongo umwe muburyo busanzwe bukoresha DFB.

Ni ngombwa kumenya ko izo nyungu zidakoresha kuri WDM gusa ahubwo no ku bakirwa babo, aho uwakiriye oscIllator yaho (dore) avangurana na generator imwe. Gukoresha buto ya Lo Shan Shan Yorohereza Ibimenyetso bya Digital Gutunganya imiyoboro ya WDM, bityo bikagabanya ibyakira bigoye no kongera umuntu urusaku.

Byongeye kandi, gukoresha ibinyabuzima byaho hamwe na Phase-Gufunga Kwakira Harafunzwe ndetse birashobora gutuma bishoboka kongere kubaka ikimenyetso-cyiza cyibimenyetso bya WDM, bityo bihatira kubungambanyi biterwa na fibre nziza. Usibye ibi byiza byifashisha bishingiye ku mazi, ingano ntoya hamwe numusaruro mwinshi kandi ufite urufunguzo rwikariso ya WDM.
Kubwibyo, mubimenyetso bitandukanye bya generator, ibikoresho bya chip-gipimo bifite inyungu zihariye. Iyo uhujwe na photonic ihuriweho cyane ya photonic ihuriweho namakuru yerekana amakuru, uko byagenda kose, inzira nkiyi ishobora gufata urufunguzo rworoshye, hamwe nubushobozi bwa WDM bushobora guhitana, hamwe nubushobozi bwa WDM bushobora guhitanwa, hamwe nubushobozi bwa WDM bugera kuri TITB / S kuri fibre.

Imiterere ikurikira irerekana igishushanyo cya WDM yandika ukoresheje uburyo bwa optique yoherezamo fcg nkuko bitandukanijwe. Binyuze kuri, ikimenyetso gikorerwa Qum Quad amplitution ampliture kubikorwa byiza bya Opmbitel (se).

Kuri transmitter egm, imiyoboro irasubirwamo muri byinshi (mux) nibimenyetso bya WDM byashyikirijwe fibre imwe. Mugihe cyakira, igice cyumurage cyakira byinshi byakira (WDM RX), ikoresha oscillator ya lown ya furfullat ya 2 fcg ya malkally uburemere. Imiyoboro yibimenyetso byinjiza WDM bitandukanijwe na sellumplexer hanyuma agaburira uwakiriye array (Coh. RX). Iyo inshuro ya demdildiplexing ya ocscillattor yaho ikoreshwa nkigiciro cyakira burikira. Imikorere ya WDM ihuza biragaragara ko biterwa nubunini bunini kuri generator yikintu cyibanze, cyane cyane ubugari bwa optique hamwe nimbaraga za optique kumurongo.

Nibyo, uburyo bwa optique ya optique ikimamara buryo bwo guteza imbere iterambere, kandi ibintu byayo byo gusaba hamwe nubunini bwisoko ni bito. Niba bishobora gutsinda ibikoresho bya tekiniki, gabanya ibiciro no kunoza kwizerwa, noneho bizashoboka kugera kubipimo ngenderwaho muburyo bwa optique.
