He aha ka mea hoʻonui EDFA

ʻO EDFA (Erbium-doped Fiber Amplifier), i hana mua ʻia i ka makahiki 1987 no ka hoʻohana ʻana i ke kālepa, ʻo ia ka mea hoʻonui optical i hoʻolaha nui ʻia ma ka ʻōnaehana DWDM e hoʻohana ana i ka fiber Erbium-doped ma ke ʻano he mea hoʻonui optical e hoʻonui pololei i nā hōʻailona. Hiki iā ia ke hoʻonui koke no nā hōʻailona me nā nalu he nui, ma loko o ʻelua mau kāʻei. ʻO kekahi ka Conventional, a i ʻole C-band, ma kahi o 1525 nm a i 1565 nm, a ʻo kekahi ʻo Long, a i ʻole L-band, ma kahi o 1570 nm a i 1610 nm. I kēia manawa, he ʻelua mau kāʻei pumping i hoʻohana pinepine ʻia, 980 nm a me 1480 nm. ʻO ka kāʻei 980nm kahi ʻāpana absorption kiʻekiʻe aʻe i hoʻohana pinepine ʻia i ka noi haʻahaʻa-walaʻau, ʻoiai ʻo ka kāʻei 1480nm kahi ʻāpana absorption haʻahaʻa akā ākea i hoʻohana pinepine ʻia no nā amplifiers mana kiʻekiʻe.

Hōʻike kikoʻī ke kiʻi ma lalo nei pehea e hoʻonui ai ka mea hoʻonui EDFA i nā hōʻailona. Ke hana ka mea hoʻonui EDFA, hāʻawi ia i kahi laser pamu me 980 nm a i ʻole 1480 nm. Ke hele ka laser pamu a me nā hōʻailona hoʻokomo ma o ka coupler, e hoʻonui ʻia lākou ma luna o ka fiber Erbium-doped. Ma o ka launa pū ʻana me nā ion doping, hiki ke hoʻokō hope ʻia ka hoʻonui ʻana i ka hōʻailona. ʻAʻole wale kēia mea hoʻonui optical āpau e hoʻohaʻahaʻa nui i ke kumukūʻai akā hoʻomaikaʻi nui i ka pono no ka hoʻonui ʻana i ka hōʻailona optical. I ka pōkole, ʻo ka mea hoʻonui EDFA kahi hanana koʻikoʻi i ka mōʻaukala o nā fiber optics hiki ke hoʻonui pololei i nā hōʻailona me nā nalu he nui ma luna o hoʻokahi fiber, ma kahi o ka hoʻonui ʻana i ka hōʻailona optical-electrical-optical.

ʻO Beijing Rofea Optoelectronics Co, Ltd aia ma "Silicon Valley" o Kina - Beijing Zhongguancun, he ʻoihana ʻenehana kiʻekiʻe i hoʻolaʻa ʻia no ka lawelawe ʻana i nā ʻoihana noiʻi kūloko a me nā ʻāina ʻē, nā ʻoihana noiʻi, nā kulanui a me nā limahana noiʻi ʻepekema ʻoihana. Ke komo nui nei kā mākou hui i ka noiʻi kūʻokoʻa a me ka hoʻomohala ʻana, ka hoʻolālā, ka hana ʻana, ke kūʻai aku ʻana i nā huahana optoelectronic, a hāʻawi i nā hoʻonā hou a me nā lawelawe ʻoihana, pilikino no nā mea noiʻi ʻepekema a me nā ʻenekinia ʻoihana. Ma hope o nā makahiki o ka hana hou kūʻokoʻa, ua hoʻokumu ʻia kahi moʻo waiwai a kūpono hoʻi o nā huahana photoelectric, i hoʻohana nui ʻia ma ke kūlanakauhale, ka pūʻali koa, ka halihali, ka mana uila, ke kālā, ka hoʻonaʻauao, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. Nā pono nui i ka ʻoihana, e like me ka hoʻopilikino ʻana, nā ʻano like ʻole, nā kikoʻī, ka pono kiʻekiʻe, ka lawelawe maikaʻi loa. A i ka makahiki 2016 ua lanakila ʻo ia i ka palapala hōʻoia ʻoihana ʻenehana kiʻekiʻe ʻo Beijing, he nui nā palapala hōʻoia patent, ikaika ikaika, nā huahana i kūʻai ʻia ma nā mākeke home a me nā ʻāina ʻē, me kāna hana paʻa, ʻoi aku ka maikaʻi e lanakila ai i ka hoʻomaikaʻi ʻana o nā mea hoʻohana ma ka home a ma waho!
