Ma kēia ʻatikala e kamaʻilio wau e pili ana i ke kumu o ka nalo ʻana i ka hoʻouna ʻana i ka fiber optics.E aʻo kākou…
ʻO ke kumu o ka hoʻololi ʻana o ka fiber optical i ka medium a me ka lōʻihi o ka hoʻouna ʻana i nā uwea pūnaewele no ka mea he haʻahaʻa loa ka hoʻoili ʻana o ka fiber optical, a ua māhele ʻia kona poho i kēia mau mea:
ʻO ka poho ka nalowale o ka ikehu māmā ma muli o ka absorption, scattering a me ka leakage o ka waena (air) i ka wā e hoʻouna ʻia ai ke kukui i loko o ka fiber optical (ʻaʻole hiki i ka fiber optical ke hoʻokaʻawale loa i ke kukui, e alakaʻi i ka leakage māmā).Hoʻonui ka nalowale o kēia ʻāpana o ka ikehu me ka mamao o ka lawe ʻana.Hoʻopau ʻia ka piʻi ʻana ma kahi kikoʻī.
No ka laʻana: 1310nm optical module e helu i ka nalowale o ka hoʻouna ʻana i ka loulou ma 0.35dBm/km,
Hoʻohālikelike ka module optical 1550nm i ka nalowale o ka hoʻouna ʻana i ka loulou ma 0.20dBm/km.A e hoʻopili pū ʻia kēia poho e nā uku like ʻole, a ʻo ka nalowale o ka hoʻouna ʻana o ka loulou e like me ka uku.
ʻO ka hoʻopuehu ʻia ma muli o ka hele ʻana o nā hawewe electromagnetic o nā nalu like ʻole i ke ʻano like ʻole i nā wikiwiki like ʻole, ka hopena i nā ʻāpana hawewe like ʻole o ka hōʻailona optical e hōʻea ana i ka hopena e loaʻa ai i nā manawa like ʻole ma muli o ka hōʻiliʻili ʻana o nā mamao hoʻouna, ka hopena i ka pulse. ka laulā a me ka hiki ʻole ke hoʻokaʻawale i ka hōʻailona.waiwai.He paʻakikī loa ka helu ʻana i ka waiwai hoʻopuehu a maʻamau wale nō no ka ʻike.
ʻO ka poho o ka hoʻokomo ʻana, ʻoiai ka lōʻihi o ka pau ʻana o ke kikowaena i loko o ka fiber optical i hoʻopaʻa ʻia, ʻaʻole i hoʻopaʻa paʻa ʻia, ka hopena o ka leakage māmā a me nā mea ʻē aʻe, e hopena i kēia poho hoʻokomo.ʻO ka maʻamau, ʻo ka poho hoʻokomo ma waena o 0.15-0.35dbm.
ʻO ka mea i luna nei he wehewehe ʻana o ka ʻike nalowale o ka lawe ʻana i ka fiber optical i lawe ʻia e Shenzhen HDV photoelectric Technology Co., Ltd. ʻO nā huahana module i hana ʻia e ka uhi ʻoihana. nā modules fiber optical, Nā modules Ethernet, nā modules transceiver fiber optical, nā modules komo fiber optical, SSFP mau modula optical, aʻO nā fiber optical SFP, etc. Hiki i nā huahana module i luna ke hāʻawi i ke kākoʻo no nā hiʻohiʻona pūnaewele like ʻole.Hiki i kahi hui R&D ʻoihana a ikaika ke kōkua i nā mea kūʻai aku me nā pilikia ʻenehana, a hiki i kahi hui ʻoihana noʻonoʻo a ʻoihana ke kōkua i nā mea kūʻai aku e loaʻa nā lawelawe kiʻekiʻe i ka wā o ka kūkākūkā mua a me ka hana ma hope o ka hana.Welina mai iā ʻoe kāhea iā mā˚ou no kēlā me kēia ʻano nīnau.
