EDFA (Erbium-doped Fiber Amplifier), yomwe idapangidwa koyamba mu 1987 kuti igwiritsidwe ntchito pazamalonda, ndiyomwe imagwiritsidwa ntchito kwambiri pamagetsi a DWDM omwe amagwiritsa ntchito Erbium-doped fiber ngati sing'anga yokulitsa mawonekedwe kuti apititse patsogolo ma signature.Imathandizira kukulitsa nthawi yomweyo kwa ma siginecha okhala ndi mafunde angapo, makamaka mkati mwamagulu awiri.Imodzi ndi Conventional, kapena C-band, pafupifupi kuchokera 1525 nm mpaka 1565 nm, ndipo ina ndi Long, kapena L-band, pafupifupi kuchokera 1570 nm mpaka 1610 nm.Pakadali pano, ili ndi magulu awiri omwe amagwiritsidwa ntchito kwambiri, 980 nm ndi 1480 nm.Gulu la 980nm lili ndi mayamwidwe apamwamba kwambiri omwe nthawi zambiri amagwiritsidwa ntchito popanga phokoso lochepa, pomwe gulu la 1480nm limakhala ndi gawo lotsika koma lalitali lomwe limagwiritsidwa ntchito ngati zokulitsa mphamvu zapamwamba.
Chithunzi chotsatirachi chikuwonetsa mwatsatanetsatane momwe EDFA amplifier imakwezera ma sign.EDFA amplifier ikagwira ntchito, imapereka laser pump yokhala ndi 980 nm kapena 1480 nm.Laser yapampu ndi zizindikiro zolowera zikadutsa pa coupler, zidzachulukitsidwa pamtundu wa Erbium-doped fiber.Kupyolera mu kuyanjana ndi ma doping ions, kukulitsa chizindikiro kumatha kukwaniritsidwa.Amplifier ya all-optical amplifier iyi sikuti imangochepetsa mtengo koma imathandizira kwambiri pakukulitsa ma signature.Mwachidule, EDFA amplifier ndi chinthu chofunika kwambiri m'mbiri ya fiber optics yomwe imatha kukulitsa mwachindunji zizindikiro ndi mafunde angapo pa fiber imodzi, m'malo mwa optical-electrical-optical signal amplification.
Beijing Rofea Optoelectronics Co, Ltd yomwe ili ku China "Silicon Valley" - Beijing Zhongguancun, Ndi bizinesi yapamwamba kwambiri yodzipereka kutumikira mabungwe ofufuza zapakhomo ndi akunja, mabungwe ofufuza, mayunivesite ndi ogwira ntchito kafukufuku wa sayansi. kufufuza ndi chitukuko, kupanga, kupanga, kugulitsa zinthu za optoelectronic, ndikupereka njira zothetsera mavuto ndi akatswiri, ntchito zaumwini kwa ofufuza asayansi ndi mainjiniya a mafakitale.Pambuyo pa zaka zopanga zodziimira pawokha, zapanga mndandanda wolemera ndi wangwiro wa mankhwala opangidwa ndi photoelectric, omwe ali ambiri. amagwiritsidwa ntchito m'matauni, asitikali, zoyendera, mphamvu yamagetsi, ndalama, maphunziro, zamankhwala ndi mafakitale ena.Ubwino waukulu pamakampani, monga makonda, mitundu, mawonekedwe, magwiridwe antchito, ntchito yabwino kwambiri.Ndipo mu 2016 adapambana bizinesi yaukadaulo ya Beijing certification, ili ndi ziphaso zambiri za patent, mphamvu zolimba, zogulitsa kunyumba ndi misika yakunja, ndikuchita kwake kokhazikika, kopambana kuti mupambane kutamandidwa kwa ogwiritsa ntchito kunyumba ndi kunja!
