Kuyini i-RF ngaphezu kwe-Fiber

KuyiniI-Rof phezu kwe-Fiber
1, Incazelo ye-RF phezu kwe-Fiber (RFOF)
Imodyuli yokudlulisa i-RF phezu kwe-Fiberiyithuluzi lokudlulisa elikhethekile elihlanganisa ukucutshungulwa kwesignali ye-RF kanye nobuchwepheshe bokuxhumana be-fiber optic. Ingqikithi yalo ukuhlanganisa amasignali e-RF nezixhumanisi zokudlulisa i-fiber optic ngokusebenzisa izindlela zokuguqula i-optoelectronic, ukuphula imikhawulo yebanga kanye nokulwa nokuphazamiseka kwendabuko.Ukudluliswa kwesignali ye-RF.
2, Imisebenzi eyinhloko ye-RF phezu kwe-Fiber
Ukuguqulwa kwesignali ye-photoelectric ekabili kuqaphela ukuguqulwa kwesignali ye-RF kanye nezibonakaliso ze-optical okukabili: ukuphela kokudlulisa kuguqula futhi kulayishe isignali ye-RF yokufaka ku-optical carrier ngamadivayisi anjenge-laser diodes, kuyiguqule ibe isignali ye-optical, bese kuyithumela kusixhumanisi se-fiber optic; Ukuphela kokwamukela kusebenzisa izingxenye ezifana nama-photodiode ukuze kususwe futhi kubuyiselwe isignali ye-optical edluliselwa ngekhebula le-fiber optic ibe isignali ye-RF, etholwa futhi icutshungulwe yimishini yangemuva.
Ukudluliswa kwesignali ye-RF esezingeni eliphezulu ekude kuncike ezicini zokuncishiswa okuphansi kanye nokuphazamiseka okulwa nogesi kwezintambo ze-optical. Ngenxa yokuqinisekisa ukwethembeka nomsindo ophansi wamagagasi esignali ye-RF, kufeza ukudluliswa kwesignali ye-RF ekude. Ibanga lokudluliswa lingandiswa kusukela kumamitha angamakhulu kuya kumakhulu amakhilomitha, kuxazululwe izindawo ezibuhlungu zokuncishiswa kwesignali enkulu kanye nokuthambekela ekuphazamisekeni kwe-electromagnetic ekudlulisweni kwekhebula le-coaxial lendabuko.
Ukulungiswa kwesignali kanye nokulungiswa kwayo kufaka phakathi ama-amplifier akhelwe ngaphakathi, izihlungi, kanye nezinye izifunda zokulungisa isignali ukuze kukhuliswe futhi kuhlungwe izibonakaliso ze-RF ngaphambi nangemva kokudluliselwa, kuthuthukiswe ikhwalithi yesignali: ukuthuthukisa ububanzi obuguquguqukayo besignali, ukunciphisa isibalo somsindo, ukuqinisekisa amandla azinzile kanye nobumsulwa bezibonakaliso ngemva kokudluliselwa ibanga elide, kanye nokuhlangabezana nezidingo zokudluliselwa kwesignali ezimweni ezahlukene.
3. Isebenza kanjani
Isiteshi Esiphakathi: sinomthwalo wokukhiqiza nokucubungula izithwali ze-optical ezithwala amasignali e-RF, lapho imishini eyinkimbinkimbi igxilile khona.
Ukudluliswa kwe-fiber optic: Izimpawu ezibonakalayo zidluliselwa ekugcineni ngokusebenzisa imicu ye-optical.
Isiteshi sesisekelo esikude: senza ukuguqulwa kwe-photoelectric kuphela, sibuyisela izimpawu ezibonakalayo zibe izimpawu zikagesi zemvamisa yomsakazo, sizikhulise, futhi sizithumele kubasebenzisi ngama-antenna; Isixhumanisi sokuxhuma siyaguqulwa.
4, Isetshenziswa kuphi kakhulu
Ukuxhumana kwe-5G/Iselula: Ukusekela ukumbozwa okungenantambo okuvama kakhulu kanye ne-bandwidth ephezulu kungenye yezindlela zobuchwepheshe eziyinhloko zokusekela ze-5G.
Uhlelo lokusabalalisa i-WiFi: luhlinzeka nge-WiFi ebangeni elide nelibanzi emafektri amakhulu, ezibhedlela, ezakhiweni ezihlakaniphile, nakwezinye izindawo.
Igridi ehlakaniphile: inethiwekhi yokuxhumana esetshenziselwa ukudlulisa, ukuguqula, kanye nokusabalalisa ugesi.
Insimu yezokuthutha: Ukuxhumana ngesivinini esiphezulu kwezimoto ezisebenzisa izitimela nemigwaqo emikhulu enesivinini esikhulu.
Ukuxhumana ngesathelayithi kanye nezempi: ukudlulisa amasignali e-broadband microwave/radio frequency ukuthuthukisa ukuphepha kohlelo.
5, izinselele zobuchwepheshe zamanje
Ukuhlanganiswa kwama-optical kanye nama-wireless chips (SOC) kanye namadivayisi e-microwave asheshayo kusantuleka kakhulu.
Uhlelo lwe-60GHz lunomthamo omkhulu we-antenna, isisindo esinzima, kanye nezindleko eziphakeme.
Izimo zokusetshenziswa zisalokhu zifana futhi azinaso isisekelo sobuchwepheshe sentuthuko enkulu.
