L-band EDFA amplifier sisitemu tekinike

1. Fibre ya Erbium
Erbium ni ikintu kidasanzwe cyisi gifite atomike ya 68 nuburemere bwa atome bwa 167.3. Urwego rwa ingufu za elegitoronike ya erbium rwerekanwe ku gishushanyo, kandi kuva mu rwego rwo hasi rw'ingufu kugera ku rwego rwo hejuru bihuye n'inzira yo kwinjiza urumuri. Guhinduka kuva murwego rwo hejuru rwingufu kugera kurwego rwo hasi rwingufu bihuye nuburyo bwohereza urumuri.

EDFA ikoresha fibre ya erbium ion nkibikoresho byunguka, itanga ihinduka ryabaturage munsi yumucyo wa pompe. Iratahura imishwarara ikwirakwizwa no kwinjiza urumuri rw'ibimenyetso.
Iyoni ya Erbium ifite urwego rwingufu eshatu. Bari kurwego rwo hasi rwingufu, E1, mugihe badashimishijwe numucyo uwo ariwo wose. Iyo fibre ihora ishimishwa na pompe yumucyo wa laser, ibice byubutaka byunguka imbaraga no kwimuka kurwego rwo hejuru. Nkinzibacyuho kuva kuri E1 ikajya kuri E3, kubera ko agace kadahungabana kurwego rwo hejuru rwingufu za E3, izahita igwa kuri leta ya E2 ishobora guhinduka mugihe cyinzibacyuho idafite imirasire. Kuri uru rwego rwingufu, ibice bifite ubuzima burebure bwo kubaho. Bitewe no gukomeza kwishima kumasoko yumucyo wa pompe, umubare wibice kurwego rwingufu za E2 bizakomeza kwiyongera, kandi umubare wibice kurwego rwingufu za E1 uziyongera. Muri ubu buryo, igabanywa ryabaturage ryagaragaye muri fibre ya erbium-dope, kandi ibyangombwa byo kwiga amplification optique birahari.
Iyo ibimenyetso byinjiza foton ingufu E = hf ihwanye neza neza nurwego rwingufu zingana hagati ya E2 na E1, E2-E1 = hf, ibice muri reta ya metastable bizahinduka mubutaka bwa E1 muburyo bwimirasire ikangura. Imirasire hamwe ninjiza Fotone iri mubimenyetso irasa na fotone, bityo byongera cyane umubare wa fotone, bigatuma ibimenyetso byinjira byinjira bihinduka ikimenyetso gikomeye gisohoka optique muri fibre ya erbium-dope, ikamenya ko byongerewe imbaraga za signal optique .
