EDFA (Erbium-doped Fiber Amplifier), oo markii ugu horreysay la ikhtiraacay 1987 si loogu isticmaalo ganacsiga, ayaa ah cod-weyneeye indhaha ugu badan ee la geeyo nidaamka DWDM ee isticmaala fiber-ka Erbium-doped dhexdhexaad ah si toos ah kor loogu qaado calaamadaha. Waxa ay awood u siinaysaa in si degdeg ah loo kordhiyo calaamadaha leh mowjadaha dhaadheer ee badan, asal ahaan waxay ku dhex jiraan laba qaybood. Mid waa Conventional, ama C-band, qiyaastii min 1525 nm ilaa 1565 nm, ka kalena waa Long, ama L-band, qiyaastii min 1570 nm ilaa 1610 nm. Dhanka kale, waxay leedahay laba bamgareynta inta badan la isticmaalo, 980 nm iyo 1480 nm. Kooxda 980nm waxay leedahay qayb nuugista sare leh oo badanaa lagu isticmaalo codsiga dhawaaqa hooseeya, halka 1480nm band ay leedahay qayb nuugista hoose oo hoose oo ballaadhan taas oo guud ahaan loo isticmaalo cod-weyneyaasha awooda sare.
Jaantuska soo socda ayaa si faahfaahsan u sharaxaya sida cod-weyneeye EDFA u wanaajiyo calaamadaha. Marka cod-weyneeye EDFA uu shaqeeyo, wuxuu bixiyaa laser bamka oo leh 980 nm ama 1480 nm. Marka leysarka bamka iyo calaamadaha wax soo gelinta ay dhex maraan lammaane, waxaa lagu badinayaa fiber-ka Erbium-doped. Iyada oo la is dhexgalka ion-doping, kor u qaadista calaamadda ayaa ugu dambeyntii la gaari karaa. Cod-weyneeye-muuqaalkan oo dhan kaliya si weyn uma dhimo qiimaha laakiin wuxuu si aad ah u wanaajiyaa hufnaanta dhawaaq-weynida isha. Marka la soo koobo, cod-weyneeye EDFA waa taariikh taariikhi ah oo fiber optics-ka ah oo si toos ah u kordhin kara calaamadaha leh mawjado badan oo ka sarreeya hal fiber, halkii ay ka ahaan lahaayeen kor u qaadida calaamadaha indhaha-korontada-optical.
