1. Gulu la bizinesi yolumikizana
Malingana ndi mitundu yosiyanasiyana ya mautumiki oyankhulana, njira zoyankhulirana zikhoza kugawidwa m'magulu olankhulana ndi telegraph, machitidwe oyankhulana ndi telefoni, njira zoyankhulirana za data, ndi njira zoyankhulirana ndi zithunzi.Chifukwa chakuti maukonde olankhulirana pa telefoni ndiwo otukuka kwambiri ndi otchuka kwambiri, njira zina zoyankhulirana kaŵirikaŵiri zimafalitsidwa kudzera m’njira zoyankhulirana zapagulu, monga kuyankhulana kwa telegalafu ndi kulankhulana kwautali wautali, zingathe kufalitsidwa kudzera mu njira ya telefoni.Integrated service digital communication network ndiyoyenera kufalitsa uthenga wamitundu yosiyanasiyana ya mautumiki.
2. Kusinthasintha kozikidwa pagulu
Malingana ndi ngati chizindikiro chomwe chimaperekedwa mu njirayo chimasinthidwa, njira yolankhulirana imatha kugawidwa mu njira yotumizira ma baseband ndi njira yotumizira bandpass.Kutumiza kwa Baseband ndikutumiza kwachindunji kwa ma siginecha osasinthika, monga mafoni am'deralo ndi kuwulutsa kwa chingwe;bandpass kufala ndi mawu wamba kufala modulated wa zizindikiro zosiyanasiyana.Pali njira zambiri zosinthira mawu.Gulu 1-1 tchulani njira zosinthira mawu.
3. Gulu molingana ndi mawonekedwe azizindikiro
Njira yolankhuliranayo imagawidwa mofanana ndi njira yolankhulirana ya analogue ndi njira yolankhulirana ya digito malinga ngati chizindikiro cha analogi kapena chizindikiro cha digito chimaperekedwa mu njira.
4. Kupatsirana sing'anga gulu
Malingana ndi njira yotumizira mauthenga, njira zoyankhulirana zikhoza kugawidwa m'magulu awiri: machitidwe oyankhulana ndi mawaya ndi machitidwe oyankhulana opanda zingwe.Kuyankhulana kwa mawaya kumagwiritsira ntchito mawaya (monga mawaya apamutu, zingwe zoyanika, ulusi wopenya, ma waveguides, ndi zina zotero) monga njira yotumizira mauthenga kuti amalize kulankhulana, monga telefoni yam'deralo, wailesi yakanema, kulankhulana kwapansi pamadzi, ndi zina zotero. mafunde a electromagnetic amayenera kuyenda mumlengalenga.Izi zimachitika kudzera pakufalitsa kwa ionospheric wawave-wave, microwave line-of-sight propagation, ndi satellite relay, mwa zina.
5. Gulu lamagulu ogwira ntchito
Zipangizo zoyankhulirana zimagawidwa m'magulu olankhulana atalitali, kuyankhulana kwapakatikati, kulankhulana kwafupipafupi, kulankhulana kwakutali, ndi zina zotero, kutengera mafupipafupi kapena kutalika kwake komwe kumagwira ntchito.
6. Gulu ndi ma sign multiplexing
Pali njira zitatu zoyambira zochulukitsa zotumizira ma siginoloji ambiri, zomwe ndi ma frequency division multiplexing, magawano a nthawi, ndi ma code division multiplexing.Frequency division multiplexing ndikugwiritsa ntchito njira yosinthira sipekitiramu kuti ma sikelo osiyanasiyana azikhala ndi ma frequency osiyanasiyana;kugawa nthawi kuchulukitsa ndikugwiritsa ntchito njira yosinthira kugunda kuti apange mazizindikiro osiyanasiyana kukhala mosiyanasiyana;ndi ma code division multiplexing ndi kugwiritsa ntchito zizindikiro za orthogonal kunyamula zizindikiro zosiyanasiyana, motsatira.Chizindikiro.Frequency division multiplexing imagwiritsidwa ntchito mukulankhulana kwachikhalidwe kwa analogi.Ndi chitukuko cha kulumikizana kwa digito, njira yolumikizirana yogawa nthawi zambiri ikugwiritsidwa ntchito kwambiri.Kuchulukitsa kwa ma code kumagwiritsidwa ntchito kwambiri polumikizirana ma spectrum ndi njira zoyankhulirana zam'manja polumikizirana mlengalenga.Kuphatikiza apo, pali magawano amtundu wochulukirachulukira, komanso kugawa kwapang'onopang'ono.
Zomwe zili pamwambazi ndi nkhani yakuti "Magulu a Njira Zolankhulana" zomwe zabweretsedwa kwa inu ndi Shenzhen HDV phoelectron Technology Co., Ltd. ndikuyembekeza kuti nkhaniyi ingakuthandizeni kuonjezera chidziwitso chanu.Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
Malingaliro a kampani Shenzhen HDV phoelectron Technology Co., Ltd.makamaka amapanga zinthu zoyankhulirana.Pakadali pano, zida zomwe zimapangidwa zimakwiriraZithunzi za ONU, Optical module mndandanda, Zithunzi za OLT,nditransceiver mndandanda.Titha kupereka ntchito makonda pazochitika zosiyanasiyana.Mwalandiridwafunsani.
