E hoʻomaopopo i nā lōʻihi nalu o 850nm, 1310nm a me 1550nm i ka fiber optical

Ua wehewehe ʻia ka mālamalama e kona lōʻihi nalu, a ma nā kamaʻilio fiber optic, aia ka mālamalama i hoʻohana ʻia ma ka ʻāpana infrared, kahi i ʻoi aku ka nui o ka nalu o ka mālamalama ma mua o ka mālamalama ʻike. Ma ke kamaʻilio fiber optical, ʻo 800 a 1600nm ka lōʻihi hawewe maʻamau, a ʻo nā nalu maʻamau i hoʻohana ʻia ʻo 850nm, 1310nm a me 1550nm.

Ke koho ʻo fluxlight i ka lōʻihi o ka hawewe, e noʻonoʻo nui ia i ka nalowale a me ka lūlū ʻana. ʻO ka pahuhopu ka hoʻouna ʻana i ka ʻikepili nui loa me ka liʻiliʻi o ka nalo fiber ma kahi mamao loa. ʻO ka nalo ʻana o ka ikaika hōʻailona i ka wā o ka lawe ʻana he attenuation. Hoʻopili ka attenuation i ka lōʻihi o ka nalu, ʻoi aku ka lōʻihi o ka nalu, ʻoi aku ka liʻiliʻi o ka attenuation. ʻO ke kukui i hoʻohana ʻia i ka fiber he lōʻihi hawewe ma 850, 1310, 1550nm, no laila ʻoi aku ka liʻiliʻi o ka attenuation o ka fiber, ʻo ia hoʻi ka hopena i ka emi ʻana o ka fiber. A ʻo kēia mau hawewe ʻekolu he ʻaneʻane ʻaʻohe absorption, ʻo ia ka mea kūpono loa no ka hoʻouna ʻana i nā fiber optical e like me nā kumu kukui i loaʻa.

I ke kamaʻilio fiber optical, hiki ke hoʻokaʻawale ʻia ka fiber optical i ka mode-mode a me ka multi-mode. ʻO ka ʻāpana hawewe 850nm ka mea maʻamau i ke ʻano kamaʻilio fiber optical multi-mode, ʻo 1550nm kahi ʻano hoʻokahi, a ʻo 1310nm ʻelua mau ʻano o ka mode-mode a me ka multi-mode. E pili ana i ka ITU-T, ua ʻōlelo ʻia ka attenuation o 1310nm e ≤0.4dB / km, a ʻo ka attenuation o 1550nm ʻo ≤0.3dB / km. A ʻo ka poho ma 850nm he 2.5dB/km. Hoʻemi maʻamau ka nalowale o ka fiber i ka piʻi ʻana o ka nalu. ʻO ka nalu waena o 1550 nm a puni ka C-band (1525-1565nm) ka mea maʻamau i kapa ʻia ʻo ka zero loss window, ʻo ia hoʻi, ʻo ka attenuation o ka fiber quartz ka mea liʻiliʻi loa ma kēia lōʻihi hawewe.

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 keʻena noiʻi kūloko a me nā ʻāina ʻē, nā keʻena noiʻi, nā kulanui a me nā limahana noiʻi ʻepekema ʻoihana. Ke hana 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 ʻoihana, nā lawelawe pilikino no nā mea noiʻi ʻepekema a me nā ʻenehana ʻenehana. Ma hope o nā makahiki o ke kūʻokoʻa kūʻokoʻa, ua hoʻokumu ʻo ia i kahi ʻano waiwai a maikaʻi loa o nā huahana photoelectric, i hoʻohana nui ʻia i ke kaona, ka pūʻali koa, ka halihali, ka mana uila, kālā, hoʻonaʻauao, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.
