Ka hookahi aaeei puluniu a me ka multimode like

I ka wa e hele mai i ka ʻikepili EYI mai kekahi kākou wahi i kekahi, mahuahua kahi o ka kuʻuna keleawe uea i ka Customer nā kānaka kūkulu kono i ka hoomoe ana i ka'ōnohi uwea. About keia pīhoihoi 'enehana mākou i kēia lā, a mākou e'ōlelo.

Puluniu-optic kamailio ana o ka laina (FOL) hana ma luna o ka loina o ka EYI o ka malamalama nalu ma kūikawā kaha i ka loa, he pōaka aniani. Pou impulses o lolouila lako a pan i hoʻolako ai i ka hoailona mīkini hoʻololi, a paha ke ke kahawai o ka malamalama ka lāʻau ikiʻai a? Aaeaao ia i ka uwea. Ma ka kekahiʻaoʻao o ka malamalama pa alima hookipa mai i kekahi kahawai, a transcodes ia hoʻi i ka electromagnetic a lāʻau ikiʻai wale. No ka mea, ke kaʻina holoʻokoʻa ua electronically lāʻau a mea he kikohoʻe huli ana, haʻahaʻa ei.

E kūkulu i ka mīkini hoʻonoho, e hoʻohana i ka kūikawā mea - hookahi-aaeei puluniu a me ka multimode.

Optic laina he ai he ākea,ʻaʻole wale no i ka nele o ke 'ākeʻakeʻa a me ka EYI o ka neaiaea. Mawaena o ka indisputable pono o kēia 'enehana mea he palahalaha koa, he loa nawaliwali hoailona attenuation, unsurpassed ia'ku i kekahi' ākeʻakeʻa o electromagnetic a ano, ka nui EYI huahelu, e na mea he nui na umi o kilomika. A nui ka pono i ka lōʻihi manawa palapala hana, waiho ka hoʻohana 'ana i ka mīkini hoʻonoho, e ma ka liʻiliʻi 25 makahiki.

'ano o ka puluniu

I ka ka piʻiʻana nā loulou hoʻohana puluniu-optic laina ua wae paha multimode a hoʻokahi 'ano paha puluniu.

He aha ka keia uwea? Na kāna mau 'ōlelo o ka puluniu mea pōaka, ultrapure aniani, a i hele ma ka malamalama mea ulana lole. Aʻawa ka mea, aole ia i ana no ka mea, o ka iwi refractive inideka haʻahaʻa ma mua o ka Kora naʻEsau, nolaila, o ka malamalama kaola no ua ihola ia lewa mai o nā pā i loko o ka puluniu.

Multimode pono no laila, i ka mea hiki ke holo mau haneri malamalama 'ole i ka wahahee ma kekahi mau pana pua. Kēlā me kēia? Aaeei i kona mau alanui, a, me ia i kaʻilihune, ka hanana propagation manawa.

I ka papa kuhikuhiE drawback o kēia 'ano o ka puluniu - aaeei lakou hoopuehu, a narrows ka bandwidth a hoʻohaiki ana i ka i kā mākou laina lōʻihi. Transmitters no ka multimode kamailio ana o ka laina e hookuu i ka i kā mākou mamao o kahi o 5 kilomika.

Ka pilikia o ka hoemi aaeei lakou hoopuehu hoʻoholo uwea me keʻano piʻina refractive inideka holoʻokoʻa o ka Kora naʻEsau. Kēia puluniu, ma ka Akä naÿe i ka maʻamau koho koho refractive inideka emi mai ka piko kāna mau 'ōlelo a hiki i ka iwi, a haawi nui hana i loko o nā mea kiko'î o ka pū i hiki neaiaea.

Ka hookahi aaeei puluniu papahana, ma muli o ka hana, hele ma ka palapala Kanal wale kekahi 'ano (walaʻauʻana). Ua kokoke he nui kona pono. Kekahi mau 'ano i loko o ka uwea, i ka hookahi-aaeei enehana, ka mea o ka nui mamua o ia i laweʻia e multimode. 'O kēia ka mea kuleana ololi e loli ai i ka poʻe uʻi a ma ka lokomaikai o na nā kānakaʻenehana mua i loko o ke kau hou puluniu optic loulou. Ua, hookahi-aaeei puluniu hoʻolako attenuation ma 0,25db no kilomika, i ke ku ei o ia mea liʻiliʻi loa a me ka laula bandwidth hoʻolako i ka ike a me ka kokololio EYI o ka nui dala o kaʻikepili me ka ei.

Akā, he mea i loko o ka mea poni nalo, i loko o ka mea poni. Kēiaʻano mea nui oi pipiʻi ma mua o multimode puluniu. No ka mea uuku loa ka nui o ka malamalama-ana nō Kora naʻEsau i loko o ka hookahi-uwea, ka pāhawewe manaʻo kōkua i loko o ia ka uwea He hana nui a me ka pono loa akahele mana i loko o splicing. Ka hopena nā mea hoʻopili i mau laina, a ua ikaika nui ae pipiʻi ma mua o multimode kontseviki laina. Eia hou, i ka hope ku pono i ka pono io o ka malamalama nana i ulana manaʻo kōkua i loko o ka palahalaha kāna mau 'ōlelo o loa na mea, nike transmitters, a i hua mai i ka nui helu o ka hoʻokūkū ana poʻe.
