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 faʻapipiʻi saʻo 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 tautuaina o faʻalapotopotoga suʻesuʻe i totonu ma fafo, suʻesuʻega inisitituti, iunivesite ma tagata faigaluega suʻesuʻega faasaienisi. suʻesuʻega ma atinaʻe, mamanu, gaosiga, faʻatauga o oloa optoelectronic, ma tuʻuina atu fofo fou ma faʻapolofesa, auaunaga faʻapitoa mo tagata suʻesuʻe faasaienisi ma inisinia alamanuia.After tausaga o faʻafouga tutoʻatasi, ua fausia ai se faasologa mauoa ma atoatoa o oloa photoelectric, lea e lautele lautele. faʻaaogaina i le municipal, militeri, felauaiga, eletise eletise, tupe, aʻoaʻoga, fomaʻi ma isi alamanuia.Great lelei i le alamanuia, e pei o customization, eseese, faʻamatalaga, maualuga maualuga, auaunaga sili.Ma i le 2016 manumalo i le pisinisi maualuga-tech Beijing faʻamaonia, e tele tusi pasi pateni, malosi malosi, oloa faʻatau atu i le fale ma fafo maketi, faʻatasi ai ma lona mautu, faʻatinoga sili atu e manumalo ai i le viia o tagata faʻaoga i le fale ma fafo!
