Ifayibha mode elilodwa multimode ngokungafani

Xa kufikwa ukudluliselwa data ukusuka kwenye indawo ekude komnye, ukwandisa endaweni ucingo lobhedu yemveli ukuya iikontraki umthengi bayamenywa ukuba ekubekeni intambo optical. Malunga oku umdla esinalo namhlanje kwaye siza sithethe.

Ifayibha-optic umgca unxibelelwano (abazo) ukusebenza kumgaqo ukudluliselwa amaza okukhanya imijelo ezizodwa ezenziwe iglasi zwi kakhulu nyulu. Ukufuna zombane izixhobo yekhompyutha enikwe a Converter umqondiso, nto leyo elenza loqukuqelo pulses ukukhanya edlulisela ukuba le ntambo. Kwelinye icala yomfumani ukukhanya ifumana emfuleni transcode bazibuyisela pulses kagesi. Ngenxa yokuba inkqubo yonke ilawulwa ngekhompyutha kwaye ukuguqulwa wedijithali, uhlaba ephantsi.

Ukuze ukwakha Umfaki ezinjalo, sebenzisa izinto ezikhethekileyo - olunye-mode ifayibha kunye multimode.

imigca yokubona baba idumile, hayi nje kuphela ngenxa yokungabikho zokuphazamisana ukudluliselwa uphawu. Phakathi iingenelo echaza lo bugcisa a band ebanzi, umqondiso eziphango buthathaka kakhulu, ukumelana nanto naluphi na uphazamiseko semvelo magnetic, omkhulu uluhlu transmission, ukwenza amashumi ezininzi yeekhilomitha. Olunye uncedo okuphawulekayo inkonzo yonxibelelwano zexesha elide, wabeka usebenzisa lokulayisha, babe neminyaka engama-25.

iintlobo ifayibha

Xa amakhonkco obandayo usebenzisa umgca fibre-optic ikhethiwe okanye multimode okanye olunye ifayibha indlela.

Yintoni na le intambo? Undoqo ifayibha na zwi, iglasi ultrapure, nayo leyo ucanda kwavela ukukhanya. A wokutshiza ayithethi lonto kuba isalathiso iqokobhe zokunganyangeki ngaphantsi undoqo, ngoko, umqadi ukukhanya kubonakala ngokupheleleyo ukusuka iindonga ngaphakathi ifayibha.

Multimode kakuhle ukuze usebenzise iindlela amakhulu eziliqela ukukhanya ebiqaliswe kwi-engile ezahlukeneyo. indlela nganye indlela yayo kwaye, ngenxa yoko, ixesha andise ekhethekileyo.

Eyona ethile le hlobo ifayibha - mode eziziintsali, leyo linciphise lo bandwidth yaye kunciphisa ubude umgca ubuninzi. Zidlulisele imida zonxibelelwano multimode idla umgama ubuninzi malunga 5 eekhilomitha.

Ingxaki yokunciphisa imo nokusasazeka isigqibo USB index zokunganyangeki ithambeka ngeprofayili core. Le ifayibha, ngokuchaseneyo isalathisi iinketho iinketho zokunganyangeki standard kunciphisa ukusuka undoqo embindini ukuya iqokobhe, nto leyo enika ukuphucuka ebalulekileyo parameters yomqondiso ngesondo.

Ifayibha mode olunye eyenzelwe, ngokusekelwe umsebenzi udlula ijelo lonxibelelwano indlela enye kuphela (esisiseko). Le ndlela ineendlela ezininzi. Ezinye iimpawu intambo, eyenziwe ubugcisa olunye-imowudi, umyalelo sezingeni ngaphezu koko eziveliswa multimode. Le yayibaluleke ochaphazela ukhetho ngakwicala ezo njineli yokuqala ekubekeni amakhonkco ezintsha ezinesigqubuthelo seplastiki. Eneneni, omnye imo ifayibha ibonelela eziphango kwi 0,25db ngekhilomitha nganye, ukungavumelani kwayo lincinane kakhulu kwaye bandwidth ngokubanzi sibonelela transmission ecacileyo okukhawulezileyo izixa ezikhulu data ngaphandle Bill.

Kodwa kukho ngamafutha ngempukane ngamafutha lawo. Olu hlobo kakhulu kubiza ngaphezu multimode nefayibha. Ukususela ubungakanani umphakathi ukukhanya-babatyeleli single-ntambo mncinane kakhulu, igalelo radiation kwi intambo onjalo mngeni kwaye ifuna ulawulo ngenyameko kakhulu usifake. Le izihlanganisi ukuphela kwezi imigca kwaye kakhulu imali eninzi kakhulu imigca kontseviki multimode. Ukongeza, ngenxa yokugqibela ukuya elula input umqadi ukukhanya ibe engundoqo ebanzi zidlulisele elula kakhulu, cheap, nayo leyo yavelisa inani elikhulu leenkampani ezikhuphisanayo.
