Ingaba umthengisi umkhohlisile umthengi? Ungoyiki, siza kukuchazela iinkcukacha.
Okokuqala, izinto eziyinxalenye yeisiphindaphindo sesignali yefayibha ye-optical
I-optical fiber repeater yenziwe ikakhulu ngamacandelo amahlanu: umatshini we-optical fiber optical okufutshane, i-optical fiber jumper, umatshini we-optical fiber okude, i-feeder jumper kunye ne-antenna yokufumana nokuthumela.
Okwesibini, umgaqo osebenzayo we-optical fiber repeater Emva kokuba isignali engenazingcingo idityaniswe ukusuka kwisiseko sesitishi, ingena kwi-near-end optical fiber repeater. I-near-end optical fiber repeater iguqula isignali ye-RF ibe yi-optical signal, ize emva koko iyithumele kwi-remote optical fiber repeater nge-optical fiber jumper, i-remote optical fiber repeater ibuyisela isignali ye-optical kwi-RF signal, ize ingene kwi-RF unit ukuze inyuswe, kwaye isignali ithunyelwa kwi-transmitter antenna emva kokwandiswa, igubungela indawo ekujoliswe kuyo.
Okwesithathu, iimpawu eziphambili zeisiphindaphindi sefayibha ye-optical
1. Sebenzisa isihluzi se-duplex esinokuzihlukanisa okuphezulu kunye nokulahleka okuncinci kokufakwa ukuze ususe i-crosstalk ephezulu neyasezantsi.
2. Le nkqubo inomsindo ophantsi, ulungelelwano oluhle, isiphumo esifanelekileyo sonxibelelwano, kwaye ayiphazamisi izikhululo zesiseko kunye nezinye izixhobo ezingenazingcingo.
3. Inenkqubo yokubeka esweni egqibeleleyo, inokubeka esweni kwaye isete iiparameter ezininzi zenkqubo, ngelixa ixhasa ukubeka esweni ngaphandle kwentambo okude, inamandla.
4. Iifayibha ezibonakalayo zisetyenziselwa ukudibanisa iziphelo zasekuhlaleni nezikude, nto leyo enika umgama omde wokudlulisela kunye nokulahleka okuncinci. Ukongeza, inethiwekhi yokutsala kunye neentlobo ngeentlobo iyaxhaswa ukuze kube lula kwaye kube lula.
5. Le modyuli ikrelekrele kwaye idityaniswe kakuhle, kulula ukuyigcina, ukuyiphucula nokuyifakela.
Okokugqibela, umahluko phakathi kwe-fiber repeater kunye ne-wireless signal repeater
Ngenxa yokuba ukuhanjiswa kwe-optical fiber repeater akuyonto yokuxhasa, akukho lahleko ngokusisiseko yokudluliselwa kwesignali yomgama omde kakhulu, kwaye ifanelekile ngakumbi kwiiprojekthi zokugubungela isignali yomgama omde kakhulu. I-wireless repeater isebenzisa ukuhanjiswa kwe-feeder, kuya kubakho ilahleko kwinkqubo yokuhanjiswa kwesignali, kwaye ilahleko iyanda ngokunyuka komgama, kwaye umgama wokuthutha awunakuthelekiswa ne-optical fiber repeater.
Nangona kunjalo, ixabiso le-optical fiber repeater liphezulu kunele-wireless repeater, enokukhethwa ngokwendawo kunye nohlahlo lwabiwo-mali.
