Iyo intera yo kohereza ari ndende cyane (irenga kilometero 100), ikimenyetso cy'urumuri kizagira igihombo gikomeye. Mu bihe byashize, abantu bakoreshaga ibikoresho bisubiramo urumuri kugira ngo bongere ikimenyetso cy'urumuri. Ubwo bwoko bw'ibikoresho bufite imbogamizi zimwe na zimwe mu mikoreshereze ifatika. Byasimbuwe na amplifier ya fiber optique. Ihame ry'imikorere ya amplifier ya fiber optique rigaragazwa ku ishusho iri hepfo. Ishobora kongera ikimenyetso cy'urumuri mu buryo butaziguye idakoresheje inzira yo guhindura optique-electron-optique.
Imashini itera inkunga fibre ikora ite?

Ni ubuhe bwoko bwa amplifier ya fibre buriho?
1. Amplifier ya fibre ikoreshwa na Erbium (EDFA)
Amplifier ya fibre ya Erbium (EDFA) igizwe ahanini na fibre ya erbium-doped, pompe light source, optical coupler, optical isolator, na optical filter. Muri byo, fibre ya erbium-doped ni igice cyingenzi cyo kongera ibimenyetso by'urumuri, ikoreshwa cyane cyane mu kugera ku 1550 nm. Band optical signal amplification, bityo, amplifier ya erbium-doped fibre amplifier (EDFA) ikora neza mu rugero rw'uburebure kuva kuri 1530 nm kugeza 1565 nm.
Aakamaro:
Ingufu nyinshi zikoreshwa na pompe (zirenze 50%)
Ishobora kongera ikimenyetso cy'urumuri mu buryo butaziguye kandi icyarimwe mu buryo butaziguye mu gice cya 1550 nm
Kongera uburebure bwa dB burenze 50
Urusaku ruto mu kohereza ubutumwa kure
ibura
Erbium-doped fiber amplifier (EDFA) ni nini kurushaho
Ibi bikoresho ntibishobora gukorana n'ibindi bikoresho bya semiconductor
2. Amplifaya ya Raman
Amplifier ya Raman ni cyo gikoresho cyonyine gishobora kongera ibimenyetso by'urumuri mu gice cya 1292 nm ~ 1660 nm. Ihame ry'imikorere yacyo rishingiye ku ngaruka za Raman zo gukwirakwiza mu mugozi wa quartz. Nkuko bigaragara ku ishusho iri hepfo, iyo urumuri rwa pompe rukuruwe Iyo ikimenyetso cy'urumuri gito muri Mann cyiyongereye umurambararo n'urumuri rukomeye rwa pompe byoherezwa icyarimwe muri mugozi wa optique, ikimenyetso cy'urumuri gito kizakongerwa bitewe n'ingaruka za Raman zo gukwirakwiza.
Aakamaro:
Urutonde rwinshi rw'imirongo ikoreshwa
Ishobora gukoreshwa mu buryo bumwe bwo gushyiramo insinga z'imigozi
Ishobora kongeraho intege nke za erbium-doped fiber amplifier (EDFA)
Ingufu zikoreshwa nke, uburyo bwo kuganira ku buryo buciriritse
inzitizi:
Ingufu nyinshi zo gupompa
Sisitemu igoye yo kugenzura inyungu

3. Amplifier ya fibre optique ya semiconductor (SOA)
Amplifiers za semiconductor optique (SOA) zikoresha ibikoresho bya semiconductor nk'uburyo bwo gukuraho amakuru, kandi uburyo bwo kwinjiza n'uko ijwi risohoka bifite uburyo bwo kwirinda kugaragara ku mpande z'inyuma z'amplifiers no gukuraho ingaruka za resonator.
Aakamaro:
ingano nto
Ingufu nke zisohoka
Uburyo bwo gukurura ni buke, ariko bushobora gukoreshwa mu byiciro byinshi bitandukanye
Ihendutse kurusha erbium-doped fiber amplifier (EDFA) kandi ishobora gukoreshwa hamwe n'ibikoresho bya semiconductor
Ibikorwa bine bidashingiye ku murongo bya cross-gain modulation, cross-phase modulation, cross-phase conversion na four-wave mixing bishobora gukorwa.
inzitizi:
Imikorere ntabwo iri hejuru nk'iya erbium-doped fiber amplifier (EDFA)
Urusaku rwinshi n'ubwiyongere buke
