Optical kulankhulana mfundo
Mfundo yolankhulirana ili motere.Pamapeto otumiza, mauthenga opatsirana (monga mawu) ayenera kusinthidwa kukhala zizindikiro zamagetsi, ndiyeno zizindikiro zamagetsi zimasinthidwa ku mtengo wa laser wotulutsidwa ndi laser (gwero la kuwala), kotero kuti mphamvu ya kuwala imasiyanasiyana ndi matalikidwe (mafupipafupi) a zizindikiro zamagetsi ndipo kupyolera mu mfundo ya kuwonetsetsa kwathunthu kwa kuwala, chizindikiro cha kuwala chimaperekedwa mu fiber optical. kufooka ndi kupotoza pambuyo popatsira patali. Chizindikiro chododometsa chimakulitsidwa pa optical repeater kuti akonze mawonekedwe osokonekera. Pamapeto olandira, chojambulira chimalandira chizindikiro cha kuwala ndikuchitembenuza kukhala chizindikiro chamagetsi, chomwe chimachotsedwa kuti chibwezeretse chidziwitso choyambirira.
Ubwino wotumizira ma fiber optic:
● Kulankhulana kwakukulu, mtunda wautali wolankhulana, kukhudzidwa kwakukulu, ndipo palibe kusokonezedwa ndi phokoso
● Kukula kochepa, kulemera kochepa, moyo wautali, khalidwe labwino komanso mtengo wotsika
● Kutsekereza, kukana kuthamanga kwambiri, kutentha kwakukulu, dzimbiri, kusinthasintha kwamphamvu
● Kusunga chinsinsi kwambiri
● Zida zopangira zinthu zambiri komanso zotsika kwambiri: Chinthu chofunika kwambiri popanga ulusi wa quartz ndi silika, womwe ndi mchenga, ndipo mchenga ndi abun.
Optical fiber communication imapangidwa ndi zida zingapo zolumikizirana.dant mwachilengedwe, kotero mtengo wake ndi wotsika.Zipangizo zowoneka bwino zimagawidwa kukhala zida zogwira ntchito komanso zida zongogwira. chizindikiro chamagetsi kukhala chizindikiro cha kuwala kapena kutembenuza chizindikiro cha kuwala kukhala chizindikiro chamagetsi, ndipo ndi mtima wa optical transmission system.Optical passive components ndi zipangizo zomwe zimafuna mphamvu yochuluka mu makina olankhulana ndi kuwala koma zilibe photoelectric kapena electro- kutembenuka kwa optic. Ndiwo ma node ofunikira a makina otumizira optical, kuphatikiza zolumikizira za fiber optic, ma wavelength division multiplexers, splitter optical, ndi kuwala.masiwichi. , zozungulira za kuwala ndi zodzipatula zamaso.
● Zingwe za fiber optic patch (zomwe zimadziwikanso kuti zolumikizira za fiber optic) zimatanthawuza mapulagi olumikizira mbali zonse ziwiri za chingwe cholumikizira. Pulagi yomwe ili kumapeto kwake imatchedwa pigtail.
● Wavelength division multiplexer (WDM) imagwirizanitsa zizindikiro za kuwala kosiyanasiyana ndi kutalika kwake kosiyanasiyana ndikuzitumiza pamodzi ndi fiber imodzi yokha. Njira yolankhulirana momwe zizindikiro za kuwala za kutalika kosiyanasiyana zimasiyanitsidwa ndi njira zina pamapeto olandira.
● Optical splitter (yomwe imadziwikanso kuti splitter) ndi chipangizo cha fiber-optic tandem chokhala ndi zolowetsa zambiri komanso zotulutsa zambiri. Malinga ndi mfundo yogawanitsa, optical splitter akhoza kugawidwa m'mitundu iwiri: mtundu wa taper wosungunuka ndi mtundu wa waveguide planar ( Mtundu wa PLC).
● Kuwalakusinthandi chipangizo chosinthira, chomwe ndi chipangizo chowunikira chokhala ndi madoko amodzi kapena angapo osankha. ntchito yake ndi thupikusinthakapena gwiritsani ntchito ma siginecha owoneka bwino mumizere yotumizira kapena njira zophatikizika za kuwala.
● The optical circulator ndi chipangizo cha multiport optical chokhala ndi makhalidwe osasinthasintha.
● Pamene chizindikiro cha kuwala chikulowetsedwa kuchokera ku doko lililonse, chimachokera ku doko lotsatira ndikutayika pang'ono mu dongosolo la digito. Ngati chizindikirocho chikulowetsedwa kuchokera ku doko 1, chikhoza kutulutsidwa kuchokera ku doko 2. Mofananamo, ngati chizindikirocho chikulowetsedwa kuchokera ku doko 2, chikhoza kutulutsidwa kuchokera ku doko 3.
● Optical isolator ndi kachipangizo kamene kamalola kuwala kopanda mbali zonse kudutsa ndi kulepheretsa kuwalako kupita kwina. Mfundo yake yogwirira ntchito imachokera ku kusafanana kwa kuzungulira kwa Faraday.
