Waveband no ka fiber optical

Waveband no ka fiber optical

ʻO ke kamaʻilio ʻana o ka fiber Optical ka māmā ma ke ʻano he mea lawe ʻike e kamaʻilio.Hiki ke hoʻoili ʻia ma o ka fiber core.Eia naʻe, ʻaʻole kūpono kēlā me kēia kukuna kukui no ke kamaʻilio.'Oko'a ke poho o ka ho'ouna 'ana me ke kaula nalu like 'ole.No ka loaʻa ʻana o ka pohō liʻiliʻi a me ka maikaʻi, ʻimi mau nā ʻepekema i ke kukui kūpono loa.

  • 850nm Waveband

I ka hoʻomaka ʻana o nā makahiki 1980, ua hoʻomaka nā ʻepekema e ʻimi i ka ʻenehana o ke kamaʻilio fiber optical ma ke ʻano kūpono.ʻO ka fiber multi-mode ka mea a lākou e aʻo nui ai.Me ka nui o ka fiber cores, hiki i ka muti-mode fiber ke hoʻomaopopo i hoʻokahi hoʻouna fiber no nā kukui muti-mode.ʻO ka māmā nalu 850nm ka mea i hoʻopili mua ʻia.

  • O Waveband

I ka hoʻomaka ʻana o nā makahiki 1990, hoʻomaka ka hoʻohana nui ʻana o ka fiber mode hoʻokahi.

Ua ʻike nā kānaka ʻepekema ʻo 1260nm ~ 1360nm waveband kukui hiki ke loaʻa ka liʻiliʻi o ka distortion hōʻailona a me ka nalowale o ka lawe ʻana ma muli o ka hoʻopuehu ʻana ma o nā hoʻokolohua.Me nā hoʻāʻo a me ka hewa, ʻike nā ʻepekema ʻo ke kukui me 1260nm ~ 1625nm aia nō hoʻi i ka liʻiliʻi loa o ka poho a ʻo ia ke kukui kūpono loa no ka lawe ʻana i ka fiber.

1260nm ~ 1625nm waveband malamalama ua maheleia i elima-O waveband, E waveband, S waveband, C waveband a me L waveband.

Ua ʻike pū ka poʻe ʻepekema i ka pilina ma waena o ka nalowale o ka lawe ʻana a me ka lōʻihi o ka nalu.E hoike ana penei.

ʻO ka mea maʻamau i hoʻohana ʻia ʻo C waveband ((1530nm ~ 1565nm), kahi e kū nei no ka "maʻamau".Hiki i ka hui C ke hoʻokō i nā poho liʻiliʻi liʻiliʻi i hoʻohana nui ʻia i ka MAN, ka lōʻihi lōʻihi, ka lōʻihi loa, nā ʻōnaehana kelepona submarine a me ka ʻōnaehana WDM.

  • L Kaha nalu (1565nm~1625nm)

ʻO L no ka "lōʻihi hawewe lōʻihi".Hiki iā L waveband ke hoʻokō i ka lua o ka hoʻoili liʻiliʻi liʻiliʻi a ʻo ia kekahi o nā koho nui no nā ʻoihana.Inā ʻaʻole hiki iā C waveband ke hoʻokō i nā pono o ka bandwidth, lawe ka poʻe i ka L waveband i mea kōkua.

  • S Waveband (1460nm~1530nm)

ʻO S no ka "lōʻihi hawewe pōkole".I ka wā e pili ana i ka poho fiber, ʻoi aku ka kiʻekiʻe ma mua o ke kaula nalu O.Hoʻohana maʻamau ia i ka lōʻihi haʻahaʻa o PON.

  • E Wave Band

ʻO ia ka puʻupuʻu maʻamau liʻiliʻi ma waena o ʻelima ʻano o ka puʻupuʻu nalu.ʻO E kū nei no ka "extended". E like me ka hōʻike ʻana mai ke kiʻi 3, hiki ke ʻike ʻia kahi puʻupuʻu ma ka hawewe E.ʻO ia no ka mea ua komo ʻia e OH- e alakaʻi ana i ka nalowale nui o ka hoʻouna ʻana, ʻo ia hoʻi i kapa ʻia ʻo wai peak.

I ka wā kahiko, ma muli o ka liʻiliʻi o ka ʻenehana, ua hui pū ʻia ka wai i loko o ke aniani fiber optical i alakaʻi i ka nalowale nui o ka hoʻouna ʻana ma E waveband a ʻaʻole hiki ke hana maʻamau.Ma hope mai, ua hoʻomohala ka poʻe i ka ʻenehana dehydration i ka hana aniani, mai ia manawa, ʻoi aku ka haʻahaʻa o ka hāʻule ʻana o ka hawewe E ma mua o ka nalu O.Eia nō naʻe, ua loaʻa ka poho o ka hoʻouna ʻana ma ka waveband E ma ke kaula fiber optical i hoʻonohonoho ʻia ma mua o ka wehewehe ʻana aia nō nā palena no ka E waveband i hoʻohana ʻia i ke kamaʻilio fiber optical.

  • U Waveband(ʻano lōʻihi loa-lōʻihi hawewe, 1625-1675 nm)

Ma waho aʻe o kēia mau hawewe nalu i ʻōlelo ʻia, hoʻohana nui ʻia ʻo U waveband, ma ka nānā ʻana i ka pūnaewele.
