1. Yintoni i-Traditional Fiber Optic Repeater?
Ngokwesiqhelo, xa abantu bebhekisa kwi-fiber optic repeater kweli shishini, bathetha nge-analog signal fiber optic repeater.
Zisebenza njani ii-fiber optic repeaters?
I-analog fiber optic repeater iguqula imiqondiso yeselula (imiqondiso ye-RF analog) ibe yimiqondiso ye-optical ukuze idluliselwe nge-fiber optics, ize emva koko iziguqulele kwimiqondiso ye-RF ekupheleni. Lo mgaqo uboniswe ngezantsi.
Xa isignali ye-analog iguqulwe yaba kukukhanya, umgangatho wesignali ye-optical uxhomekeka kakhulu kwiimpawu zokudluliselwa kwefayibha, nto leyo edla ngokubangela ukuphazamiseka kwesignali, ingxolo, kunye neminye imiba.
Umgaqo oSebenzayo weFiber Optic Repeater
Ngaphezu koko, ii-repeaters ze-analog fiber optic zemveli zihlala zinengxaki yokulawula i-gain control kunye ne-ingxolo depress, nto leyo eyenza kube nzima ukufikelela kuhlengahlengiso oluchanekileyo lwesignali kunye nokulungiswa kwayo.
Umzekelo, ii-analog fiber optic repeaters zeLintratek zinomgama ophezulu wokudlulisela we-5km kuphela, kwaye ukudluliselwa kwe-multi-band kusengozini yokuphazamiseka. Kwiimeko ezinama-frequency bands amaninzi, ukuba ama-band amabini ane-frequency efanayo, ukuphazamiseka kwesignali kunye nokuphazamiseka kunokwenzeka ngokulula ngexesha lokudlulisela.

2. Yintoni iDigital Fiber Optic Repeater?
Njengoko igama lisitsho, i-digital fiber optic repeater yinguqulelo ephuculweyo ye-analog fiber optic repeater yendabuko. Uphuculo oluphambili kukuba iqale iguqule imiqondiso yeselula (ii-RF analog signals) ibe yimiqondiso yedijithali ngaphambi kokuba iziguqule zibe yimiqondiso ye-optical yokudlulisela. Ekugqibeleni, imiqondiso ibuyiselwa njengemiqondiso yedijithali ize iguqulwe ibe yimiqondiso yeselula yokuhanjiswa kwiifowuni zabasebenzisi. Lo mgaqo uboniswe ngezantsi.
Ngokwenyani, i-digital fiber optic repeater yongeza inyathelo elongezelelweyo lokuguqula imiqondiso ibe yimo yedijithali ngaphambi kokuba idluliselwe.
Umgaqo oSebenzayo weDigital Fiber Optic Repeater
Ngokuphathelele umgangatho wesignali, iteknoloji yokucubungula isignali yedijithali (i-DSP) isusa ngokufanelekileyo ingxolo kunye nokuphazamiseka ngexesha lokusasazwa, nokuba kwiimeko ezinamabhendi amaninzi apho amabhendi eefrikhwensi asondelelene, okuqinisekisa ukusasazwa kwesignali okuthembekileyo kwaye kugcinwa uzinzo kunye nokuthembeka konxibelelwano.
Ukongeza, ii-repeaters ze-fiber optic zedijithali zibonelela ngokuchanekileyo okuphezulu kunye nokuguquguquka ekulawuleni i-gain kunye nokukhetha amaza. Ezi repeaters zinokulungisa kwaye ziphucule umgangatho wesignali ngokusekelwe kwindawo ethile yenethiwekhi kunye neemfuno zeshishini.
