    ʻO nā mea āu e ʻike ai he wi-fi, akā ʻo nā mea a pau āu e ʻike ai he kamaʻilio fiber-optic

    Ka manawa kau: Aug-08-2019

    WIFI

    No laila, no ke aha ka wikiwiki o ka hoʻouna ʻana o ke kamaʻilio fiber-optic? He aha ke kamaʻilio fiber? He aha nā mea maikaʻi a me nā hemahema ke hoʻohālikelike ʻia me nā ʻano kamaʻilio ʻē aʻe? Ma nā wahi hea e hoʻohana ʻia ai ka ʻenehana i kēia manawa?

    Ka hoʻouna ʻana i ka ʻike me ka māmā i ka fiberglass.

    Ma ke ʻano he uea, ʻaʻole hiki ke kamaʻilio fiber-optic i nā pono o ke kelepona. Ma ke ola o kēlā me kēia lā, hoʻohana kā mākou kamaʻilio kelepona i nā ʻupena uila, a ʻaʻole ikaika ka hele ʻana o ka kamaʻilio optical.

    Akā ʻo ka ʻoiaʻiʻo, ʻoi aku ka nui o ka 90% o ka ʻike ma o ka fiber optics. Hoʻopili ʻia ke kelepona paʻa i ka base station ma o kahi pūnaewele uea, a ʻo ka hoʻouna ʻana i nā hōʻailona ma waena o nā kahua kahua e hilinaʻi nui ʻia i ka fiber optical."He Zhixue, ka hope luna o ka Optical System Research Office o ka State Key Laboratory o Optical Fiber Communication Network Technology, i ʻōlelo ʻia ma kahi ninaninau me ka Science and Technology Daily.

    ʻO ka fiber Optical kahi fiber optical e like me ka lahilahi e like me ka lauoho, hiki ke kanu pololei ʻia, ma luna o ke poʻo, a kau ʻia paha ma ka papahele o ke kai. e like me ke ano o ka hoailona hoailona.

    No ka maʻalahi, ʻo ka kamaʻilio fiber optical ka noi maʻamau o ka kamaʻilio optical, e like me nā kukui uila telescope, a me nā mea ʻē aʻe, hoʻohana lākou i ka lewa e hoʻolaha i nā kukui ʻike ʻia, no ka ʻike ʻike optical kamaʻilio ka hoʻohana ʻana i ke aniani fiber i ka mālamalama. hoʻouna ʻike.

    Ua haʻi aku kekahi loea kamaʻilio optical i ka sci-tech i kēlā me kēia lā e emi ana nā hōʻailona optical i ka wā o ka lawe ʻana ma mua o nā hōʻailona uila. Ua wehewehe ʻo ia, no ka laʻana, hoʻopau ka hōʻailona optical mai 1 a 0.99 ma hope o 100 mau kilomita, aʻo kahi hōʻailona uila e pohō mai ka 1 a hiki i ka 0.5 ma hope o 1 kilomika.

    Mai ka manaʻo o ka manaʻo, ʻo nā mea kumu kumu i hoʻokumu ʻia i ke kamaʻilio fiber optical he kumu kukui fiber optical a me ka mea ʻike maka.

    ʻO ka mana nui a me ka hiki ke hoʻouna lōʻihi

    Wahi a nā hōʻike, ʻo ke ala hope loa o ke komo ʻana i ka fiber-optic broadband he fiber-to-the-home, ʻo ia hoʻi, e hoʻopili pololei i ka fiber i kahi i makemake ʻia e ka mea hoʻohana, i hiki ke loaʻa ka nui o ka ʻike ma o ka hoʻohana ʻana i ka. pulupulu.

    "He mea maʻalahi ke ala kamaʻilio uila i ka interference electromagnetic, a ʻoi aku ke kumu kūʻai o ke ala hoʻouna kelepona. ʻO ka ʻokoʻa, ʻoi aku ka maikaʻi o ke kamaʻilio fiber optical i ka mana nui, hiki ke hoʻouna i ka mamao lōʻihi, ka hūnā maikaʻi, a me ka hiki ke hoʻololi. Eia kekahi, liʻiliʻi ka nui o ka fiber a maʻalahi hoʻi e hoʻohana. ʻO ke kūkulu ʻana a me ka mālama ʻana, ʻoi aku ka haʻahaʻa o nā kumukūʻai maka. Ua ʻōlelo ʻo He Zhixue.

    ʻOiai ʻo ke kamaʻilio fiber-optic nā mea maikaʻi ma luna, ʻaʻole hiki ke mālama ʻia kāna papa pōkole ponoʻī. No ka laʻana, palupalu a maʻalahi ka haki ʻana o ka fiber. Eia kekahi, ʻo ka ʻoki ʻana a i ʻole ka hoʻopili ʻana i ka fiber pono e hoʻohana i kahi mea kikoʻī. Pono e hoʻomaopopo ʻia ʻo ke kūkulu ʻana i ke kūlanakauhale a i ʻole nā ​​pōʻino kūlohelohe hiki ke hana maʻalahi i ka hāʻule ʻana o ka laina fiber.

    Ma nā noi kūpono, ʻo ka hoʻokō ʻana i ka hoʻouna ʻana i ka fiber optical e hilinaʻi nui ʻia i ka mīkini hope hoʻouna optical a me ka mīkini hope loaʻa optical. Hiki ke hoʻololi a hoʻololi i ka hōʻailona electro-optical, a laila e hoʻololi i ka hōʻailona uila i kahi hōʻailona optical i lawe ʻia e ka fiber optical. ʻO ka hopena o kaʻikeʻike e hana i ka hoʻololi hoʻohuli a hiki ke hoʻohaʻahaʻa i ka hōʻailona uila.ʻO ka hopena o kaʻike a me ka hopena o ka hoʻounaʻana e pili ana i kahi mea hoʻohui i kahi kaula uila eʻike ai i ka laweʻana, ka laweʻana, ka hoʻokipa a me ka hōʻikeʻike.

    Pili nā lako hana kiʻekiʻe e pili ana i ka lawe ʻana mai

    ʻO nā fiber optical maʻamau i hoʻohana nui ʻia nā fiber optical mode hoʻokahi. Ma ke kumumanaʻo, ʻo ka wikiwiki o ka lawe ʻana i ka ʻike i kēlā me kēia manawa ma kahi o 140 Tbit/s. Inā hiki i kēia palena ka wikiwiki o ka hoʻouna ʻana i ka ʻike, e hōʻemi ia i ka ʻike. ʻO ka fiber mode hoʻokahi ka mea maʻamau he fiber hiki ke hoʻouna i hoʻokahi mode.

    I kēia manawa, ʻo ke kamaʻilio fiber optical mode hoʻokahi maʻamau kekahi o nā ala kamaʻilio maʻamau e hoʻohana ʻia e nā mea hana. ʻO ka mana hoʻoili o kēia ʻano he 16 Tbit/s, ʻaʻole i hiki i ka waiwai palena theoretical. "ʻO ka moʻolelo hou o 1.06Pbit / s, i paʻi ʻia i ka hoʻomaka ʻana o kēia makahiki, ʻo ia ka hopena o nā holomua i ka ʻenehana kamaʻilio fiber-optic mode hoʻokahi, akā paʻakikī kēlā wikiwiki e hoʻokō i ka hoʻohana ʻana i ka ʻoihana i kahi manawa pōkole o manawa. Ua ʻōlelo ʻo He Zhixue.

    Ma ke ʻano ʻenehana, i hoʻohālikelike ʻia me ka mode hoʻokahi, multi-core fiber transmission mode i ʻoi aku ka maikaʻi o ka loaʻa ʻana o ka wikiwiki kiʻekiʻe, akā aia nō kēia ʻano i ka mua, a pono nā holomua hou i nā ʻenehana koʻikoʻi, nā ʻāpana kī, a me nā lako lako. .

    Ma hope o 5 a 10 mau makahiki, ma lalo o ka ikaika o nā koi noi, hiki ke hoʻohana mua ʻia nā ʻenehana koʻikoʻi o 1.06Pbit/s ultra-large capacity single-mode multi-core optical fiber transmission system i kekahi mau hiʻohiʻona kūikawā, e like me ka transoceanic transmission a me kekahi. kikowaena ʻikepili nui. Ua ʻōlelo ʻo He Zhixue.

    I kēia manawa, hiki i ka ʻenehana kamaʻilio optical o Kina ke hoʻokūkū me ka pae kiʻekiʻe o ka honua, akā ke alo nei i nā pilikia he nui. No ka laʻana, nāwaliwali ka waihona ʻoihana pili, nele i ka ʻenehana kumu a me ka ʻenehana kūʻokoʻa, a ʻaʻole lawa ka fiber optic maka. "I kēia manawa, ʻo nā mea hana kiʻekiʻe e pono ai no ka hana ʻana i nā mea fiber e like me ke kaha kiʻi uea a me ka wili ʻana o ka fiber e hilinaʻi ʻia i ka lawe ʻana mai." Ua ʻōlelo ʻo He Zhixue.

    Ma ka manawa like, ʻo nā mea hana kiʻekiʻe a me nā chips e pili ana i ke kamaʻilio fiber optical e hoʻomalu nui ʻia e nā ʻāina i kūkulu ʻia e like me ʻAmelika Hui Pū ʻIa a me Iapana.

    Ma keia manao, ua manao o He Zhixue he mea pono e hooikaika i ka noiʻi kumu kumu pili, e hana i ka hana maikaʻi o ka lōʻihi lōʻihi hoʻonohonoho o nā 'ike loea, wānana i ka ulu ana o ka 'ike loea, a lele i waho o ka 'ike loea hou pōʻaiapuni o ka "tracking. -lag-re-tracking-a hoʻi hope".

    Eia hou, ua hoʻokūpaʻaʻo He Zhixue he mea pono e hoʻonui i ka hoʻokomoʻana i ka noiʻi a me ka hoʻomohalaʻana, ka hoʻolālā a me ka hanaʻana i nā'āpana kiʻekiʻe a me nā mea hana kiʻekiʻe, e hoʻoulu i ka hoihoi o nā kālena R&D, a me ka nānāʻana i ka paleʻana i nā mea i loaʻa mua. "ʻO ka mea nui, pono mākou e hana i kahi hoʻolālā kiʻekiʻe, e hoʻokō i ka synergy a me ka hana hou i ka manpower, nā ʻōnaehana, a me nā kulekele, a hoʻomaikaʻi i nā mana kākoʻo o nā ʻoihana pili," wahi āna.
