Amplifier ya EDFA ni iki?

EDFA (Erbium-doped Fiber Amplifier), yavumbuwe bwa mbere mu 1987 kugira ngo ikoreshwe mu bucuruzi, ni yo amplifier y'amajwi ikoreshwa cyane muri sisitemu ya DWDM ikoresha fibre ya Erbium-doped nk'uburyo bwo kongera ingufu z'amajwi kugira ngo yongere ubushobozi bw'amajwi. Ituma habaho amplifier yihuse ku majwi afite uburebure bwinshi bw'umurambararo, muri rusange mu mirongo ibiri. Imwe ni Conventional, cyangwa C-band, iri hagati ya 1525 nm na 1565 nm, indi ni Long, cyangwa L-band, iri hagati ya 1570 nm na 1610 nm. Hagati aho, ifite imirongo ibiri ikoreshwa cyane yo gupompa, 980 nm na 1480 nm. Umurongo wa 980nm ufite igice cyo hejuru cyo kwinjiza gikunze gukoreshwa mu gukoresha urusaku ruke, mu gihe umurongo wa 1480nm ufite igice cyo hasi ariko kinini cyo kwinjiza gikunze gukoreshwa mu byuma bitanga ingufu nyinshi.

Ishusho ikurikira igaragaza neza uburyo amplifier ya EDFA yongera ibimenyetso. Iyo amplifier ya EDFA ikoze, itanga lazeri ya pompe ifite 980 nm cyangwa 1480 nm. Iyo lazeri ya pompe n'ibimenyetso byinjira binyuze muri coupler, bizashyirwa kuri fibre ya Erbium-doped. Binyuze mu guhuza na iyoni za doping, kongera ibimenyetso bishobora kugerwaho. Iyi amplifier ya optique yose ntabwo igabanya cyane ikiguzi ahubwo yongera cyane imikorere yo kongera ibimenyetso bya optique. Muri make, amplifier ya EDFA ni intambwe ikomeye mu mateka ya fibre optique ishobora kongera ibimenyetso mu buryo butaziguye hamwe n'uburebure bwinshi bw'umuraba kuri fibre imwe, aho kongera ibimenyetso bya optique-electric-optical.

Beijing Rofea Optoelectronics Co, Ltd iherereye mu "Silicon Valley" mu Bushinwa - Beijing Zhongguancun, ni ikigo gikoresha ikoranabuhanga rihanitse cyihaye inshingano zo gukorera ibigo by'ubushakashatsi byo mu gihugu no mu mahanga, ibigo by'ubushakashatsi, za kaminuza n'abakozi b'ubushakashatsi bwa siyansi mu bigo. Isosiyete yacu ikora cyane cyane ubushakashatsi bwigenga n'iterambere, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi itanga ibisubizo bishya na serivisi z'umwuga, zihariye ku bashakashatsi ba siyansi n'abahanga mu nganda. Nyuma y'imyaka myinshi y'udushya twigenga, yakoze urukurikirane rw'ibicuruzwa bikungahaye kandi byuzuye by'amashanyarazi, bikoreshwa cyane mu nganda z'umujyi, igisirikare, ubwikorezi, ingufu z'amashanyarazi, imari, uburezi, ubuvuzi n'izindi nganda. Ibyiza bikomeye mu nganda, nko guhindura ibintu, ubwoko butandukanye, imiterere, imikorere myiza, serivisi nziza. Kandi mu 2016 yegukanye icyemezo cy'ubucuruzi buhanitse bwa Beijing, ifite ibyemezo byinshi bya patenti, imbaraga zikomeye, ibicuruzwa bigurishwa mu masoko yo mu gihugu no mu mahanga, hamwe n'imikorere yayo ihamye kandi ihebuje yo gushimirwa n'abakoresha mu gihugu no mu mahanga!
