Kodi EDFA Amplifier ndi chiyani?

EDFA (Erbium-doped Fiber Amplifier), yomwe idapangidwa koyamba mu 1987 kuti igwiritsidwe ntchito pamalonda, ndiyo amplifier yowunikira yomwe imagwiritsidwa ntchito kwambiri mu DWDM system yomwe imagwiritsa ntchito ulusi wopangidwa ndi Erbium ngati njira yowunikira yowunikira kuti iwonjezere mwachindunji zizindikiro. Imalola kukulitsa nthawi yomweyo kwa zizindikiro zokhala ndi mafunde ambiri, makamaka mkati mwa magulu awiri. Limodzi ndi Conventional, kapena C-band, pafupifupi kuyambira 1525 nm mpaka 1565 nm, ndipo linalo ndi Long, kapena L-band, pafupifupi kuyambira 1570 nm mpaka 1610 nm. Pakadali pano, ili ndi magulu awiri opompa omwe amagwiritsidwa ntchito kwambiri, 980 nm ndi 1480 nm. Gulu la 980nm lili ndi gawo lolowera kwambiri lomwe nthawi zambiri limagwiritsidwa ntchito popanga phokoso lotsika, pomwe gulu la 1480nm lili ndi gawo lolowera lolowera lotsika koma lalikulu lomwe nthawi zambiri limagwiritsidwa ntchito popanga ma amplifier amphamvu kwambiri.

Chithunzi chotsatirachi chikuwonetsa mwatsatanetsatane momwe amplifier ya EDFA imakulitsira zizindikiro. Pamene amplifier ya EDFA ikugwira ntchito, imapereka laser ya pampu yokhala ndi 980 nm kapena 1480 nm. Pamene laser ya pampu ndi zizindikiro zolowera zimadutsa mu coupler, zidzawonjezeredwa pa ulusi wopangidwa ndi Erbium. Kudzera mu kulumikizana ndi ma ions a doping, kukulitsa chizindikiro kumatha kuchitika. Amplifier iyi ya all-optical sikuti imangochepetsa mtengo komanso imawongolera kwambiri magwiridwe antchito a optical signal amplification. Mwachidule, amplifier ya EDFA ndi gawo lofunika kwambiri m'mbiri ya fiber optics yomwe imatha kukulitsa zizindikiro mwachindunji ndi ma wavelength angapo pa ulusi umodzi, m'malo mwa optical-electric-optical signal amplification.

Kampani ya Beijing Rofea Optoelectronics Co, Ltd yomwe ili ku "Silicon Valley" ku China - Beijing Zhongguancun, ndi kampani yapamwamba kwambiri yodzipereka kutumikira mabungwe ofufuza akunja ndi akunja, mabungwe ofufuza, mayunivesite ndi ogwira ntchito zofufuza zasayansi. Kampani yathu imagwira ntchito yofufuza ndi kupanga zinthu za optoelectronic payokha, kupanga, kupanga, kugulitsa zinthu za optoelectronic, ndipo imapereka mayankho atsopano komanso ntchito zaukadaulo kwa ofufuza asayansi ndi mainjiniya amakampani. Pambuyo pa zaka zambiri zodzipangira zinthu payokha, yapanga mndandanda wolemera komanso wangwiro wazinthu zamagetsi, zomwe zimagwiritsidwa ntchito kwambiri m'maboma, asilikali, mayendedwe, mphamvu zamagetsi, ndalama, maphunziro, zamankhwala ndi mafakitale ena. Ubwino waukulu mumakampaniwa, monga kusintha, mitundu, mawonekedwe, magwiridwe antchito apamwamba, ntchito yabwino kwambiri. Ndipo mu 2016 idapambana satifiketi yamakampani apamwamba ku Beijing, ili ndi ziphaso zambiri za patent, mphamvu zamphamvu, zinthu zogulitsidwa m'misika yakunja ndi kunja, ndi magwiridwe ake okhazikika, apamwamba kwambiri kuti ipambane chiyamiko cha ogwiritsa ntchito kunyumba ndi kunja!
