Ingabe umthengisi ukhohlisile ikhasimende? Ungesabi, sizokuchazela imininingwane.
Okokuqala, izingxenye zeisiphindaphindo sesiginali yefayibha yokukhanya
I-optical fiber repeater yakhiwe kakhulu ngezingxenye ezinhlanu: umshini we-optical fiber oseduze, i-optical fiber jumper, umshini we-remote optical fiber, i-feeder jumper kanye ne-antenna yokwamukela nokudlulisa.
Okwesibili, isimiso sokusebenza se-optical fiber repeater Ngemva kokuthi isignali engenantambo ihlanganiswe esiteshini sesisekelo, ingena kwi-near-end optical fiber repeater. I-near-end optical fiber repeater iguqula isignali ye-RF ibe isignali ye-optical, bese iyidlulisela kwi-remote optical fiber repeater nge-optical fiber jumper, i-remote optical fiber repeater ibuyisela isignali ye-optical esignalini ye-RF, bese ingena kwiyunithi ye-RF ukuze ikhuliswe, bese isignali ithunyelwa kwi-antenna edlulisa ngemuva kokukhulisa, imboze indawo eqondiwe.
Okwesithathu, izici eziyinhloko zeisiphindaphindi sefayibha ye-optical
1. Sebenzisa isihlungi se-duplex esinokwehlukaniswa okuphezulu kanye nokulahlekelwa okuphansi kokufakwa ukuze ususe ukuxoxa okungaphezulu nangaphansi komfula.
2. Uhlelo lunomsindo ophansi, ukulingana okuhle, umphumela omuhle wokuxhumana, futhi aluphazamisi iziteshi zesisekelo neminye imishini engenantambo.
3. Inesistimu yokuqapha ephelele, ingaqapha futhi isethe amapharamitha amaningi esistimu, ngenkathi isekela ukuqapha okungenantambo okude, inamandla.
4. Imicu yokubona isetshenziswa ukuxhumanisa iziphetho zendawo nezikude, okunikeza ibanga elide lokudlulisa kanye nokulahlekelwa okuncane. Ngaphezu kwalokho, inethiwekhi yokudonsa kanye ne-multiple isekelwa ukuze kube lula futhi kube nokuguquguquka.
5. Imodyuli ihlakaniphile futhi ihlanganiswe kahle kakhulu, okulula ukuyinakekela, ukuyithuthukisa nokuyifaka.
Okokugcina, umehluko phakathi kwe-fiber repeater kanye ne-wireless signal repeater
Ngenxa yokuthi ukudluliselwa kwe-optical fiber repeater akusiyona eyondlayo, akukho ukulahlekelwa okubangelwa ukudluliselwa kwesignali yebanga elide kakhulu, futhi kufaneleka kakhulu kumaphrojekthi okumboza isignali yebanga elide kakhulu. I-wireless repeater isebenzisa ukudluliselwa kwe-feeder, kuzoba nokulahlekelwa enkambisweni yesignali yokuthutha, futhi ukulahlekelwa kuyanda ngokwanda kwebanga, futhi ibanga lokuhamba alinakuqhathaniswa ne-optical fiber repeater.
Kodwa-ke, intengo ye-optical fiber repeater nayo iphakeme kuneye-wireless repeater, engakhethwa ngokuya ngendawo kanye nesabelomali.
