Niki Amplifier ya EDFA

EDFA (Erbium-Dope Fibre Amplifier), yahimbwe bwa mbere mu 1987 kugirango ikoreshwe mu bucuruzi, niyo ikoreshwa cyane ya optique amplifier muri sisitemu ya DWDM ikoresha fibre ya Erbium ikoreshwa nka optique ya amplification optique kugirango izamure neza ibimenyetso. Ifasha guhita yongerera ibimenyetso ibimenyetso bifite uburebure bwinshi, cyane mubice bibiri. Imwe ni Ibisanzwe, cyangwa C-band, hafi ya 1525 nm kugeza 1565 nm, indi ni Long, cyangwa L-band, hafi kuva 1570 nm kugeza 1610 nm. Hagati aho, ifite ibice bibiri bikunze gukoreshwa kuvoma, 980 nm na 1480 nm. Itsinda rya 980nm rifite igice kinini cyo kwinjiza igice gisanzwe gikoreshwa mugukoresha urusaku ruke, mugihe 1480nm band ifite igice cyo hasi ariko cyagutse cyo kwinjizamo igice gikunze gukoreshwa mubyongerewe imbaraga.

Igishushanyo gikurikira kirerekana neza uburyo amplifier ya EDFA yongera ibimenyetso. Iyo amplifier ya EDFA ikora, itanga pompe laser ifite 980 nm cyangwa 1480 nm. Iyo pompe laser hamwe nibimenyetso byinjira byanyuze kuri kupler, bizagwiza hejuru ya fibre ya Erbium. Binyuze mu mikoranire na doping ion, ibimenyetso byongera ibimenyetso birashobora kugerwaho amaherezo. Ibi byose-optique amplifier ntabwo igabanya cyane ikiguzi ahubwo izamura cyane imikorere ya optique ya signal optique. Muri make, amplifier ya EDFA nintambwe yibanze mumateka ya fibre optique ishobora kongera ibimenyetso byerekana uburebure bwumurongo mwinshi hejuru ya fibre imwe, aho kuba optique-amashanyarazi-optique yerekana ibimenyetso.

Beijing Rofea Optoelectronics Co, Ltd iherereye mu Bushinwa “Silicon Valley” - Beijing Zhongguancun, Ni uruganda rukora ubuhanga buhanitse bwita ku bigo by’ubushakashatsi bw’imbere mu gihugu ndetse n’amahanga, ibigo by’ubushakashatsi, kaminuza ndetse n’abakozi bashinzwe ubushakashatsi mu bya siyansi. uruhererekane rw'ibicuruzwa bifotora, bikoreshwa cyane mu makomine, igisirikare, ubwikorezi, ingufu z'amashanyarazi, imari, uburezi, ubuvuzi n'izindi nganda. Inyungu nini mu nganda, nko gutunganya ibicuruzwa, ibintu bitandukanye, ibisobanuro, gukora neza, serivisi nziza. Kandi mu mwaka wa 2016 yatsindiye icyemezo cya tekinoloji y’ibigo by’ikoranabuhanga rya Beijing, gifite ibyemezo byinshi by’ipatanti, imbaraga zikomeye, ibicuruzwa bigurishwa mu mahanga ndetse no mu mahanga bikoresha amasoko mu gihugu ndetse no mu mahanga, kugira ngo bitsindire, bikoresha neza mu mahanga ndetse no mu mahanga, kandi bifite umusaruro ushimishije, bikoresha neza mu gihugu no mu mahanga.
