L-Band PODFA Nidaamka Farsamada ee Nidaamka

1. Furuurum-Fibriiska
Erbium waa mid naadir ah oo leh tiro atom ah oo ah 68 iyo culeys atomitaan ah 167.3. Heerka tamarta elektiroonigga ah ee elektiroonigga ah ayaa lagu muujiyey shaxanka, iyo kala-guurka ee ka socda heerka tamarta hoose ilaa heerka tamar sare waxay u dhigantaa hanaanka nuugista ee iftiinka. Isbedelka ka yimaada heerka tamarta sare ilaa heerka tamarta hoose wuxuu u dhigantaa geedi socodka qulqulka iftiinka.

2. EDFA Mabda '

EDFA waxay u isticmaashaa fiber ion-fiber-ka ah sida heerka dhexdhexaadka ah, kaas oo soo saara dadka is-dhexgalka dadka ee ku dhaca iftiinka. Waxay xaqiiqsataa inaad dhiirrigeliso codka shucaaca shucaaca iyadoo la raacayo nalka iftiinka.
Ions Erbium waxay leeyihiin seddex heerar tamar ah. Waxay ku sugan yihiin heerka tamarta ugu yar, E1, markii aysan ku faraxsanayn wax fudud. Marka fiberku uu si joogto ah ugu farxo iftiinka iftiinka nalka iftiinka, walxaha ku jira gobolka ayaa hela tamar iyo u-gudbinta heerka tamar sare. Sida kala-guurka ee E1 illaa E3, sababta oo ah walxaha waa kuwa aan xasilloonayn heerka tamarta sare ee E3, waxay si dhakhso leh ugu dhici doontaa dowlad-wadaag meas ah oo ah hannaanka kala-guurka ee aan-ka-beddela. Heerka tamar ee tamar, walxaha waxay leeyihiin nolol badbaado dheer. Sababo la xiriira ilkaha joogtada ah ee isha iftiinka bamka, tirada walxaha ku jira heerka tamarta E2 ayaa sii wadi doona kordhinta, iyo tirada walxaha ku jira heerka tamarta ee E1 ay sii kordhayaan. Sidan, qaybinta dadka ee dadku waxay ku ogaanayaan fiber-ka-erbium-fiber-ka, xaaladaha cod-weyne muuqaallona waa la heli karaa.
Marka sawirka ret time photon emer earf E = HF waxay si sax ah u dhigantaa farqiga u dhexeeya heerka tamarta ee u dhexeeya E2 iyo E1, E1-E1 = HF, E1-E1 = HF, E1-E1-ah ee gobolka meteaab-ka ayaa u gudbaya gobolka E1 ee ah qaab shucaaca kiciya. Shucaaca iyo soo-jeedinta sawirku ee seenyaalaha ayaa isku mid ah sawirrada, sidaa darteed waxay si weyn u sii kordhayaan nambarka sawirrada, iyagoo ka dhigaya calaamad muuqaallo muuqaal ah oo soo saarta fiber-ka-soo-saarka ee fiber-ka, garashada cod-weynaha tooska ah ee calaamadaha indhaha.

2. Jaantusyada Nidaamka iyo Hordhac aqalka aasaasiga ah
2.1. Jaantusyada Nidaamka Nidaamka Nidaamka Fooska Obilical ee 'L-POWCIFIER' waa sida soo socota:

2.2. Jaantusyada Nidaamka Nidaamka Isha Isha ee Isugeynta ee ASE ee ku dhaca fiber-ka frbium-fiber-ka waa sida soo socota:
