Halaye naNa'urar ƙara haske ta EDFA
Tsawon aiki na EDFANa'urar ƙara haske ta ganiYa faɗi daidai a cikin mafi kyawun kewayon tsawon zango na 1330-1600nm don sadarwa ta fiber optic. An yi amfani da na'urar ƙara girman haske ta EDFA da ke aiki a cikin C-band (1530-1565nm) tare da mafi ƙarancin taga asarar fiber sosai. Domin cikakken amfani da albarkatun bandwidth na zaruruwan gani, mutane kuma sun himmatu wajen haɓaka na'urar ƙara girman haske ta EDFA a cikin L-band (1570-1610nm). L-band yana nan a wutsiyar ƙarfin ƙarfin haske na EDFA, don haka L-band EDFA Optical Amplifier dole ne ya yi amfani da zaruruwa masu tsayi da ƙarfin famfo mai girma, ko kuma ya yi amfani da zaruruwa masu yawan doping.
EDFA Optical Amplifier yana da babban riba (fiye da 30-50dB) kuma yana ba da fa'ida mai faɗi akan faɗin mitar mita (har zuwa 30nm), wanda hakan ya dace da siginar ƙara girma a cikin tashoshi da yawa na gani, musamman a cikin tsarin multiplexing mai yawa na tsawon rai (DWDM). Ƙarancin hayaniya (4-8dB), yana kusantar iyakar adadi. Lokacin da aka yi amfani da shi ga tsarin WDM, ana rage magana tsakanin tashoshi kuma ana iya haɗa amplifiers da yawa. Yana da ƙarfin fitarwa mai yawa (10-20 dBm), ana iya amfani da shi azaman amplifier mai ƙarfi bayan mai watsawa don ƙara nisan watsawa ko adadin nodes na gani da aka ware ba tare da layukan relay ba. Ƙarfin famfon da ake buƙata yana da ƙasa (dubun milliwatts). Ribar ba ta dogara da yanayin polarization na zaren ba, don haka yana da kyakkyawan kwanciyar hankali. Sauƙin haɗawa da zaruruwan gani na watsawa, tare da ƙarancin asarar haɗin gwiwa (<1dB). Banda tushen famfon,Amplifier na EDFAya ƙunshi sassa marasa aiki.
