Rof Electro-optic modulator EDFA Adkeeyaha Indhaha Erbium Doped Fiber Adkeeyaha YDFA Adkeeyaha

Amplifier-ka indhaha waa qalab hela iftiin calaamadeed oo soo saara calaamad muujinaysa wax soo saarka oo leh awood sare oo iftiin ah. Caadiyan, wax soo gelinta iyo wax soo saarku waa fallaadho laysar ah (noocyo aad u dhif ah oo iftiin iftiin ah), oo ku faafa sida fallaadho Gaussian ah meel bannaan ama faybar. Ballaarinta waxay ka dhacdaa waxa loogu yeero dhexdhexaadka faa'iidada, kaas oo ah in "lagu shubo" (tusaale ahaan, la siiyo tamar) laga helo ilo dibadda ah. Inta badan cod-weyneeyayaasha indhaha waxaa lagu shubaa si indhaha ah ama koronto ahaan.
Noocyada kala duwan ee qalabka cod-weyneeyaha aad bay u kala duwan yihiin tusaale ahaan marka la eego sifooyinka dheregga. Tusaale ahaan, qalabka cod-weyneeyaha ee laser-ka ee dhulka ku shaqeeya ee dhifka ah ayaa kaydin kara tamar badan, halka qalabka cod-weyneeyaha ee parametric-ka ee indhaha uu bixiyo cod-weyneeye kaliya ilaa inta uu bamka ku jiro. Tusaale kale, qalabka cod-weyneeyaha ee semiconductor-ku wuxuu kaydiyaa tamar aad uga yar qalabka cod-weyneeyaha ee fiber-ka, taasina waxay leedahay saameyn muhiim ah oo ku saabsan isgaarsiinta fiber-ka indhaha.
