O le a le EDFA Amplifier

O le EDFA (Erbium-doped Fiber Amplifier), na muamua faia i le 1987 mo le faʻaaogaina faapisinisi, o le faʻapipiʻi faʻapipiʻi sili ona faʻapipiʻiina i le DWDM system lea e faʻaogaina ai le fiber Erbium-doped e pei o le faʻapipiʻi faʻapipiʻi faʻapipiʻi e faʻaleleia saʻo ai faailoilo. E mafai ai ona fa'ateleina fa'avave mo fa'ailo e tele galu umi, fa'atatau i totonu o fusi e lua. O le tasi o le Faiga masani, poʻo le C-band, pe a ma le 1525 nm i le 1565 nm, ma le isi o le Long, poʻo le L-band, pe a ma le 1570 nm i le 1610 nm. I le taimi nei, e lua e masani ona faʻaaogaina pamu pamu, 980 nm ma 1480 nm. O le 980nm band e maualuga atu le absorption cross-section e masani ona faʻaaogaina i le maualalo o le pisa, ae o le 1480nm band o loʻo i ai se laʻititi laʻititi ae sili atu le lautele o le absorption cross-section lea e masani ona faʻaaogaina mo le maualuga o le eletise.

O le ata o lo'o i lalo o lo'o fa'amatala manino mai ai le fa'asiliina o fa'ailoga e le amplifier EDFA. A galue le EDFA amplifier, e ofoina atu le laser pamu ma le 980 nm poʻo le 1480 nm. O le taimi lava e pasi atu ai le laser pamu ma faʻailoga faʻapipiʻi i totonu o le mea faʻapipiʻi, o le a faʻapipiʻiina i luga o le fiber Erbium-doped. E ala i le fegalegaleai ma le doping ions, e mafai ona ausia mulimuli ane le faʻalauteleina o faʻailoga. O lenei mea fa'apipi'i fa'apitoa uma e le gata ina fa'aitiitia ai le tau ae fa'aleleia atili ai le lelei mo le fa'alauteleina o fa'ailoga. I se faapuupuuga, o le EDFA amplifier o se mea taua i le tala faasolopito o fiber optics e mafai ona faʻalauteleina faʻailoga ma le tele o galu i luga o le tasi fiber, nai lo le faʻapipiʻiina o faʻailoga eletise-eletise-optical.

Beijing Rofea Optoelectronics Co, Ltd o loʻo i totonu o Saina "Silicon Vanu" - Beijing Zhongguancun, O se atinaʻe tekonolosi maualuga e tuʻuina atu i le tautua i totonu o fale ma fafo faʻalapotopotoga suʻesuʻe, inisitituti suʻesuʻe, iunivesite ma atinaʻe suʻesuʻega faasaienisi personnel.Our kamupani e tele lava ina auai i le suʻesuʻega tutoʻatasi ma atinaʻe, mamanu, gaosiga, faʻatauga o oloa optoelectronic, ma tuʻuina atu fofo fou ma faʻainisinia faʻainisinia faʻainisinia tausaga faʻapolofesa. fou, ua fausia ai se faasologa mauoa ma atoatoa o oloa photoelectric, lea e masani ona faaaoga i le municipal, militeli, felauaiga, malosiaga eletise, tupe, aoaoga, faafomai ma isi alamanuia.Great lelei i le alamanuia, e pei o customization, eseese, specifications, maualuga le lelei, auaunaga sili.Ma i le 2016 manumalo le Beijing maualuga-tech faamaonia pisinisi, ua i ai le tele o oloa gaosi oloa faʻatau atu, pateni faʻatau oloa, faʻatau oloa faʻatau, faʻatau oloa i fafo ma le tele manumalo i le viia o tagata faaaoga i le fale ma fafo!
