Kodi RF ndi chiyani kuposa Fiber?

Kodi ndi chiyaniRof pamwamba pa Ulusi
1, Tanthauzo la RF pa Ulusi (RFOF)
Gawo lotumizira la RF pamwamba pa Fiberndi chipangizo chapadera chotumizira mauthenga chomwe chimagwirizanitsa kukonza ma signal a RF ndi ukadaulo wolumikizirana ndi fiber optic. Cholinga chake chachikulu ndikuphatikiza ma signal a RF ndi ma fiber optic transmission links kudzera mu njira zosinthira ma optoelectronic, kudutsa malire a mtunda ndi kuletsa kusokonezedwa mu njira zachikhalidwe.Kutumiza kwa chizindikiro cha RF.
2, Ntchito zazikulu za RF pa Ulusi
Kusintha kwa chizindikiro chamagetsi cha mbali ziwiri kumazindikira kusintha kwa zizindikiro za RF ndi zizindikiro zowala: gawo lotumizira limasinthasintha ndikuyika chizindikiro cha RF cholowera pa chonyamulira chowala kudzera muzipangizo monga ma laser diode, ndikuchisintha kukhala chizindikiro chowala, ndikuchitumiza ku ulalo wa fiber optic; Gawo lolandira limagwiritsa ntchito zigawo monga ma photodiode kuti lichotse ndikubwezeretsa chizindikiro chowala chomwe chimatumizidwa kudzera mu chingwe cha fiber optic kukhala chizindikiro cha RF, chomwe chimalandiridwa ndikukonzedwa ndi zida za backend.
Kutumiza chizindikiro cha RF chapamwamba kwambiri pa mtunda wautali kumadalira makhalidwe a kuchepa kwa mphamvu ndi kusokoneza kwa maginito a kuwala. Pofuna kuonetsetsa kuti mafunde a maginito a RF ndi odalirika komanso otsika, zimathandiza kuti maginito a RF afalitsidwe pa mtunda wautali. Mtunda wotumizira ukhoza kufalikira kuchokera pa mamita mazana ambiri mpaka makilomita mazana ambiri, kuthetsa ululu wa kuchepa kwa mphamvu ya chizindikiro chachikulu komanso kusokonezeka kwa mphamvu yamagetsi mu kutumiza chingwe cha coaxial chachikhalidwe.
Kukonza ndi kukonza ma siginolo kumaphatikizapo ma amplifiers omangidwa mkati, zosefera, ndi ma circuits ena okonza ma siginolo kuti akweze ndikusefa ma siginolo a RF asanayambe komanso atangotumizidwa, kukonza bwino mtundu wa ma siginolo: kukonza mphamvu ya ma siginolo, kuchepetsa phokoso, kuonetsetsa kuti ma siginolo ali olimba komanso oyera bwino akatumizidwa mtunda wautali, komanso kukwaniritsa zosowa za ma siginolo m'malo osiyanasiyana.
3, Kodi imagwira ntchito bwanji
Siteshoni yapakati: yomwe imayang'anira kupanga ndi kukonza zonyamulira zamagetsi zomwe zimanyamula zizindikiro za RF, komwe zida zovuta zimakhala zodzaza.
Kutumiza kwa kuwala kwa fiber: Zizindikiro za kuwala zimatumizidwa kumadera akutali kudzera mu ulusi wa kuwala.
Siteshoni yakutali: imangosintha ma photoelectric, imabwezeretsa ma optical signals kukhala ma radio frequency electrical signals, imawonjezera, ndikutumiza kwa ogwiritsa ntchito kudzera mu ma antenna; uplink imasinthidwa.
4, Kodi imagwiritsidwa ntchito bwanji makamaka
Kulankhulana kwa 5G/Mafoni: Kuthandizira kufalikira kwa mawayilesi opanda zingwe pafupipafupi komanso pa bandwidth yayikulu ndi imodzi mwa njira zazikulu zothandizira 5G.
Njira yogawa WiFi: kupereka chithandizo cha WiFi chakutali komanso chachikulu m'mafakitale akuluakulu, zipatala, nyumba zanzeru, ndi malo ena.
Gridi yanzeru: netiweki yolumikizirana yomwe imagwiritsidwa ntchito potumiza, kusintha, ndi kugawa magetsi.
Malo oyendera: Kulankhulana kwa magalimoto mwachangu kwambiri pa sitima ndi misewu ikuluikulu.
Kulankhulana kwa satellite ndi asilikali: kutumiza zizindikiro za ma microwave/ma wailesi othamanga kwambiri kuti ziwonjezere chitetezo cha makina.
5, Mavuto aukadaulo omwe alipo panopa
Kuphatikiza ma chips optical ndi opanda waya (SOC) ndi zipangizo zama microwave zothamanga kwambiri sikukukwanirabe.
Dongosolo la 60GHz lili ndi mphamvu yaikulu ya antenna, kulemera kwakukulu, komanso mtengo wake ndi wokwera.
Zochitika zogwiritsira ntchito zidakali chimodzi chokha ndipo sizili ndi maziko aukadaulo oti pakhale chitukuko chachikulu.
