He aha ka EDFA Amplifier

ʻO EDFA (Erbium-doped Fiber Amplifier), i hana mua ʻia ma 1987 no ka hoʻohana ʻana i ka ʻoihana, ʻo ia ka mea hoʻonui optical i hoʻopili ʻia ma ka ʻōnaehana DWDM e hoʻohana ana i ka fiber Erbium-doped e like me ka mea hoʻonui optical e hoʻonui pololei i nā hōʻailona. Hāʻawi ia i ka hoʻonui koke ʻana i nā hōʻailona me nā lōʻihi hawewe he nui, ma loko o ʻelua mau kaha. ʻO kekahi ka Conventional, a i ʻole C-band, ma kahi o 1525 nm a 1565 nm, a ʻo kekahi ʻo ka Long, a i ʻole L-band, ma kahi o 1570 nm a 1610 nm. Eia nō naʻe, ʻelua mau puʻupuʻu maʻamau i hoʻohana ʻia, 980 nm a me 1480 nm. ʻO ka band 980nm kahi ʻāpana absorption kiʻekiʻe i hoʻohana pinepine ʻia i ka noi haʻahaʻa haʻahaʻa, ʻoiai ʻo 1480nm band he haʻahaʻa haʻahaʻa akā ʻoi aku ka laulā absorption cross-section i hoʻohana mau ʻia no nā mea hoʻonui mana kiʻekiʻe.

Hōʻike kikoʻī ke kiʻi ma lalo nei pehea e hoʻonui ai ka amplifier EDFA i nā hōʻailona. Ke hana nei ka amplifier EDFA, hāʻawi ia i ka laser pump me 980 nm a i ʻole 1480 nm. Ke hele ka laser pump a me nā hōʻailona hoʻokomo i ka hui, e hoʻonui ʻia lākou ma luna o ka fiber Erbium-doped. Ma o ka launa pū ʻana me nā iona doping, hiki ke hoʻokō ʻia ka hoʻonui ʻana i ka hōʻailona. ʻAʻole hoʻohaʻahaʻa loa kēia amplifier āpau āpau i ke kumukūʻai akā hoʻomaikaʻi nui i ka pono no ka hoʻonui ʻana i ka hōʻailona optical. I ka pōkole, ʻo ka EDFA amplifier kahi mea nui i ka mōʻaukala o ka fiber optics hiki ke hoʻonui pololei i nā hōʻailona me nā lōʻihi hawewe 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 Kina "Silicon Valley" - Beijing Zhongguancun, He ʻoihana ʻenehana kiʻekiʻe i hoʻolaʻa ʻia no ka lawelawe ʻana i nā hale noiʻi kūloko a me nā ʻāina ʻē, nā keʻena noiʻi, nā kulanui a me nā limahana noiʻi ʻepekema ʻoihana. noiʻi a me ka hoʻomohala ʻana, hoʻolālā, hana, kūʻai aku i nā huahana optoelectronic, a hāʻawi i nā hoʻonā hou a me ka ʻoihana, nā lawelawe pilikino no nā mea noiʻi ʻepekema a me nā ʻenehana ʻenehana. hoʻohana ʻia i ke kaona, ka pūʻali koa, ka halihali, ka mana uila, ke kālā, ka hoʻonaʻauao, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. ʻO nā pōmaikaʻi nui i ka ʻoihana, e like me ka hana maʻamau, nā ʻano like ʻole, nā kikoʻī, ka hana kiʻekiʻe, ka lawelawe maikaʻi loa. ka palapala hōʻoia, he nui nā palapala patent, ikaika ikaika, nā huahana i kūʻai ʻia ma ka home a me nā mākeke ʻē aʻe, me kāna hana paʻa, ʻoi aku ka maikaʻi e lanakila ai ka mahalo o nā mea hoʻohana ma ka home a ma waho!
