1. Faibha yakasanganiswa neErbium
Erbium chinhu chisingawanzoitiki chine nhamba yeatomu ye68 uye huremu hweatomu hwe167.3. Simba remagetsi reerbium ion rinoratidzwa mumufananidzo, uye kuchinja kubva padanho repasi resimba kuenda padanho repamusoro resimba kunoenderana nemaitiro ekunyudzwa kwechiedza. Kuchinja kubva padanho repamusoro resimba kuenda padanho repasi resimba kunoenderana nemaitiro ekuburitsa chiedza.
2. Musimboti weEDFA
EDFA inoshandisa erbium ion-doped fiber senzira yekuwana simba, iyo inogadzira population inversion pasi pepombi light. Inoita kuti radiation amplification iwedzere pasi pe induction yesignal light.
Maion eErbium ane mazinga matatu esimba. Ari padanho repasi resimba, E1, kana asina kufambiswa nechiedza. Kana fiber ichiramba ichifambiswa ne laser yechiedza chepombi, zvidimbu zviri muvhu zvinowana simba uye zvinochinja kuenda padanho repamusoro resimba. Sekuchinja kubva kuE1 kuenda kuE3, nekuti zvidimbu hazvina kugadzikana padanho repamusoro resimba reE3, zvinokurumidza kudonha kusvika padanho remetastable E2 mukuchinja kusingasvibisi. Padanho iri resimba, zvidimbu zvine hupenyu hwakareba. Nekuda kwekuwedzeredzwa kunoramba kuripo kwechiedza chepombi, huwandu hwezvidimbu padanho resimba reE2 hucharamba huchiwedzera, uye huwandu hwezvidimbu padanho resimba reE1 huchawedzera. Nenzira iyi, kupararira kwehuwandu hwezvinhu kunowanikwa mufiber yakasanganiswa neerbium, uye mamiriro ekudzidza kuwedzera kwe optical amplification anowanikwa.
Kana simba re photon re input signal E=hf rakaenzana chaizvo nemusiyano we level yesimba pakati peE2 neE1, E2-E1=hf, zvidimbu zviri mu metastable state zvinozochinja kuenda ku ground state E1 muchimiro che stimulated radiation. Mwaranzi ne input Ma photon ari mu signal akafanana nema photon, nokudaro zvichiwedzera zvakanyanya nhamba yema photon, zvichiita kuti input optical signal ive strong output optical signal mu erbium-doped fiber, zvichiita kuti direct amplification ye optical signal iite.
