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.

Pekin Rofea Optoelectronics Co, Ltd iherereye mu Bushinwa “Silicon Valley” - Beijing Zhongguancun, Ni ikigo cy’ikoranabuhanga rikomeye ryita ku bigo by’ubushakashatsi mu gihugu no mu mahanga, ibigo by’ubushakashatsi, kaminuza ndetse n’abakozi bashinzwe ubushakashatsi mu bumenyi. Isosiyete yacu ikora cyane cyane mu bwigenge. ubushakashatsi niterambere, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi bitanga ibisubizo bishya hamwe na serivise zumwuga, zihariye kubashakashatsi ba siyanse naba injeniyeri mu nganda. Nyuma yimyaka yo guhanga udushya twigenga, yakoze urukurikirane rukungahaye kandi rwuzuye rwibicuruzwa bifata amashanyarazi, bikaba byinshi ikoreshwa mu makomine, igisirikare, ubwikorezi, ingufu z'amashanyarazi, imari, uburezi, ubuvuzi n'izindi nganda. Inyungu nini mu nganda, nko gutunganya ibicuruzwa, gutandukana, ibisobanuro, gukora neza, serivisi nziza.Kandi muri 2016 yatsindiye ikigo cy’ikoranabuhanga cya Beijing Icyemezo, gifite ibyemezo byinshi byipatanti, imbaraga zikomeye, ibicuruzwa bigurishwa kumasoko yimbere mugihugu ndetse no hanze yarwo, hamwe nibikorwa bihamye, byiza cyane kugirango ushimire abakoresha mugihugu ndetse no mumahanga!
