Ndiye, nchifukwa ninji liwiro la kutumizirana kwa fiber-optic kuyankhulana kuli mwachangu kwambiri?Kodi fiber communication ndi chiyani?Kodi ubwino ndi zofooka zake ndi ziti poyerekeza ndi njira zina zolankhulirana?Kodi luso laukadaulo likugwiritsidwa ntchito pati?
Kutumiza uthenga ndi kuwala mu fiberglass.
Monga netiweki yamawaya, kulumikizana kwa fiber-optic sikungakwaniritse zosowa za mafoni.M'moyo watsiku ndi tsiku, kulumikizana kwathu kwa mafoni kumagwiritsa ntchito maukonde opanda zingwe, ndipo kupezeka kwa kulumikizana kwa kuwala sikukuwoneka kolimba.
“Koma zenizeni, zoposa 90% za chidziwitsocho zimafalitsidwa kudzera mu fiber optics.Foni yam'manja imagwirizanitsidwa ndi malo oyambira kudzera pa intaneti yopanda zingwe, ndipo kutumiza zizindikiro pakati pa malo oyambira nthawi zambiri kumadalira fiber optical."He Zhixue, wachiwiri kwa director of Optical System Research Office of the State Key Laboratory of Optical Fiber Communication Network Technology, adatero poyankhulana ndi Science and Technology Daily.
Optical fiber ndi chingwe cha kuwala chomwe chimakhala chochepa kwambiri ngati tsitsi, chikhoza kukwiriridwa mwachindunji, pamwamba, kapena kuikidwa pansi pa nyanja. ngati njira yayikulu yotumizira ma signal.
Kunena mophweka, kuwala CHIKWANGWANI kulankhulana ndi ntchito wamba wa kuwala kulankhulana, monga nyali zoyendera telesikopu, etc., iwo ntchito mlengalenga kufalitsa kuwala looneka, ndi wa zithunzi kufala kuwala kulankhulana ndi ntchito galasi CHIKWANGWANI mu kuwala. mauthenga opatsirana.
Katswiri wolumikizana ndi mawonedwe adauza sci-tech tsiku lililonse kuti ma siginecha amawola amawola pang'ono pakupatsirana kuposa ma siginecha amagetsi.Iye anafotokoza kuti, mwachitsanzo, chizindikiro cha kuwala chimawola kuchokera ku 1 mpaka 0,99 pambuyo pa makilomita 100, pamene chizindikiro cha magetsi chimawola kuchokera ku 1 mpaka 0,5 pambuyo pa kilomita imodzi yokha.
Kuchokera pamalingaliro a mfundo, zinthu zoyambira zomwe zimapanga kulumikizana kwa fiber ndi kuwala kwa fiber ndi chowunikira chowunikira.
Kuthekera kwakukulu komanso kuthekera kotumiza mtunda wautali
Malinga ndi malipoti, njira yabwino kwambiri yopezera fiber-optic broadband access ndi fiber-to-the-home, ndiko kuti, kulumikiza ulusi mwachindunji kumalo ofunikira kwa wogwiritsa ntchito, kuti athe kupeza zambiri zambiri pogwiritsa ntchito fiber.
"Njira yolumikizirana opanda zingwe imatha kusokonezedwa ndi ma electromagnetic, ndipo njira yotumizira chingwe ndiyokwera mtengo kuyiyala.Mosiyana ndi izi, kuyankhulana kwa fiber optical kuli ndi ubwino wokhala ndi mphamvu zazikulu, kutha kutumizira mtunda wautali, chinsinsi chabwino, ndi kusinthasintha kwakukulu.Komanso, ulusiwo ndi wocheperako komanso wosavuta kugwiritsa ntchito.Zomanga ndi kukonza, mitengo ya zinthu zopangira ndi yotsika kwambiri. ”Adatero Zhixue.
Ngakhale kulumikizana kwa fiber-optic kuli ndi zabwino zomwe zili pamwambapa, bolodi lake lalifupi silinganyalanyazidwe.Mwachitsanzo, ulusiwo ndi wophwanyika komanso wosweka mosavuta.Kuphatikiza apo, kudula kapena kulumikiza ulusi kumafuna kugwiritsa ntchito chipangizo china.Ndikoyenera kudziwa kuti zomangamanga m'matauni kapena masoka achilengedwe angayambitse kulephera kwa fiber line.
Muzochita zogwira ntchito, kukwaniritsidwa kwa ma transmitter optical fiber makamaka kumadalira makina omaliza otumizira optical ndi makina omaliza olandila.Chipangizo chakumapeto kwa magetsi chimatha kusintha bwino ndikusintha chizindikiro cha electro-optical, potero kutembenuza chizindikiro chamagetsi kukhala chizindikiro cha kuwala chomwe chimatengedwa ndi fiber optical.Mapeto olandila owoneka amatha kusinthanso kutembenuka ndipo amathanso kutsitsa chizindikiro chamagetsi.Mapeto olandila optical ndi optical transmitting end amalumikizidwa ndi cholumikizira ku chingwe chowunikira kuti azindikire kutumiza, kutumiza, kulandira ndikuwonetsa chidziwitso.
Zida zopangira zida zapamwamba zogwirizana zimadalira zogulitsa kunja
Ulusi wowoneka bwino womwe umagwiritsidwa ntchito nthawi zambiri ndi ulusi wamtundu umodzi wokha.Mwachidziwitso, kuthamanga kwa chidziwitso pa nthawi ya unit ndi pafupifupi 140 Tbit / s.Ngati liwiro la kutumiza uthenga lifika pamlingo uwu, zingayambitse kusokonezeka kwa chidziwitso.Single mode fiber nthawi zambiri imakhala CHIKWANGWANI chomwe chimatha kufalitsa njira imodzi yokha.
Pakali pano, njira yolumikizirana ya single-mode optical fiber ndi imodzi mwa njira zoyankhulirana zomwe zimagwiritsidwa ntchito kwambiri ndi ogwira ntchito.Mphamvu yotumizira yamtunduwu ndi 16 Tbit / s, yomwe siinafike pamlingo wowerengera."Nkhani yatsopano ya 1.06Pbit / s, yomwe idasindikizidwa kumayambiriro kwa chaka chino, ndi zotsatira za luso loyankhulana la fiber-optic la single-mode fiber-optic, koma kuthamanga koteroko n'kovuta kukwaniritsa malonda mu nthawi yochepa. nthawi.”Adatero Zhixue.
Mwaukadaulo, poyerekeza ndi single-mode, multi-core fiber transmission mode ili ndi zabwino zambiri pakukwaniritsa liwiro lalikulu, koma njirayi ikadali patsogolo, ndipo zotsogola zina zimafunikira paukadaulo wapakatikati, zida zazikulu, ndi zida za Hardware..
Pambuyo pa zaka 5 mpaka 10, mothandizidwa ndi zofunikira zogwiritsira ntchito, matekinoloje ofunikira a 1.06Pbit/s ultra-large capacity single-mode multi-core optical fiber transmission system atha kugwiritsidwa ntchito pazochitika zina zapadera, monga transoceanic transmission ndi zina. wamkulu wa Data Center. ”Adatero Zhixue.
Pakali pano, China kuwala kulankhulana luso akhoza kupikisana ndi mlingo wapadziko lonse lapansi, koma akukumana ndi mavuto ambiri.Mwachitsanzo, maziko a mafakitale ofunikira ndi ofooka, alibe ukadaulo wodziyimira pawokha, komanso ukadaulo wosakwanira wa fiber optic."Pakadali pano, zida zapamwamba zomwe zimafunikira popanga zida za fiber monga kujambula mawaya ndi kutsekereza kwa fiber zimadalira kuchokera kunja."Adatero Zhixue.
Nthawi yomweyo, zida zapamwamba komanso tchipisi chokhudzana ndi kulumikizana kwa fiber optical zimayendetsedwa makamaka ndi mayiko otukuka monga United States ndi Japan.
Pachifukwa ichi, He Zhixue adanenanso kuti ndikofunikira kulimbikitsa kafukufuku wofunikira, kuchita ntchito yabwino yakusanjika kwanthawi yayitali kwaukadaulo wapakatikati, kulosera za chitukuko chaukadaulo, ndikudumpha kuchoka pamayendedwe aukadaulo a "kutsata. -kuchedwa-kutsata-ndi kubwerera m'mbuyo".
Kuonjezera apo, He Zhixue anatsindika kuti ndikofunikira kuonjezera ndalama zofufuza ndi chitukuko, kupanga ndi kukonza tchipisi tapamwamba ndi zipangizo zamakono, kulimbikitsa chidwi cha matalente a R & D, ndikuyang'ana pa kuteteza zomwe zachitika poyamba."Makamaka, tiyenera kupanga mapangidwe apamwamba, kukwaniritsa mgwirizano ndi luso la anthu ogwira ntchito, zomangamanga, ndi ndondomeko, komanso kupititsa patsogolo luso lothandizira mafakitale omwe akugwirizana nawo," adatero.
