L-Band EdFA Amplifarier System Schendume

Edfa amagwiritsa ntchito valium ion-dopden fiber monga momwe amathandizira kuti anthu azikuponya kuwala. Imazindikira kukonzedwa mu radiation pansi pa mawonekedwe a kuwala.
Erbium ions ili ndi milingo itatu yamagetsi. Ali pamlingo wotsika kwambiri, E1, pomwe sakusangalala ndi kuwala kulikonse. Pamene chiberekero chimakondwera ndi gwero la pampukusaka, tinthu tating'onoting'ono timapeza mphamvu ndi kusintha kwamphamvu kwambiri. Monga kusintha kuchokera ku E3, chifukwa tinthu sikukusunthika pamlingo waukulu wa e3, idzagwera mwachangu e2 munjira yosasinthika yosinthira. Pa mphamvu imeneyi, tinthu tambiri timakhala ndi moyo wautali kwambiri. Chifukwa cha kukolola mosalekeza kwa gwero la kampuli, chiwerengero cha tinthu tating'onoting'ono tomwe tatha kuchuluka kwa E2 chidzapitilirabe, ndipo kuchuluka kwa tinthu pa E1. Mwanjira imeneyi, magawidwe osokoneza a chiwerengero omwe amadziwika mu Verbium-DIBEDIN
Ngati chizindikiro cha Photon Photon Energy E = HF ndichofanana ndendende pakati pa e2 ndi e1, e2-e2 = hf, tinthu tating'onoting'ono tomwe timalimbikitsidwa. Ma radiation ndi kulowetsa zithunzithunzi mu chizindikirocho ndizofanana ndi zithunzizo, ndikuwonjezera nambala ya mahotolo, zomwe zimapangitsa kuti chizindikiro chowoneka bwino chizikhala ngati chizindikiro champhamvu kwambiri.

2. Chithunzi chojambulidwa ndi chida choyambirira
2.1. Chithunzi chojambulidwa cha L-Bank Optical Fish Symplifar ndi motere:
