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

Ua wehewehe ʻia ke kukui e kona nalu lōʻihi, a i loko o nā kamaʻilio fiber optic, aia ke kukui i hoʻohana ʻia ma ka ʻāpana infrared, kahi i ʻoi aku ai ka nalu lōʻihi o ke kukui ma mua o ke kukui ʻike ʻia. I ke kamaʻilio fiber optical, ʻo ka nalu lōʻihi maʻamau he 800 a 1600nm, a ʻo nā nalu lōʻihi i hoʻohana pinepine ʻia he 850nm, 1310nm a me 1550nm.

Ke koho ke kukui uila i ka nalu hoʻoili, noʻonoʻo nui ia i ka nalowale o ka fiber a me ka hoʻopuehu ʻana. ʻO ka pahuhopu ka hoʻoili ʻana i ka ʻikepili nui loa me ka nalowale fiber liʻiliʻi loa ma luna o ka mamao lōʻihi loa. ʻO ka nalowale o ka ikaika hōʻailona i ka wā o ka hoʻoili ʻana he attenuation. Pili ka attenuation i ka lōʻihi o ke ʻano nalu, ʻo ka lōʻihi o ke ʻano nalu, ʻoi aku ka liʻiliʻi o ka attenuation. ʻOi aku ka lōʻihi o ka nalu o ke kukui i hoʻohana ʻia i loko o ka fiber ma 850, 1310, 1550nm, no laila ʻoi aku ka liʻiliʻi o ka attenuation o ka fiber, kahi e hopena ai i ka emi ʻana o ka nalowale fiber. A ʻaneʻane ʻole ka omo ʻana o kēia mau nalu ʻekolu, ʻo ia ka mea kūpono loa no ka hoʻoili ʻana i nā fiber optical ma ke ʻano he kumu kukui i loaʻa.

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