Iifiber ze-Optical zizitshaneli ezinengcingo ezithumela imiqondiso yokukhanya. Sibhekisela kwiimpawu zombane ezingeyomfuneko kwitshaneli njengengxolo. Ingxolo kwinkqubo yonxibelelwano ibekwe ngaphezulu kumqondiso, kwaye kukho ingxolo kwinkqubo yonxibelelwano xa kungekho mqondiso wothumelo, a...

Ijelo lidibanisa isixhobo sonxibelelwano sesiphelo sokuthumela kunye nesiphelo sokufumana, kwaye umsebenzi walo kukudlulisa umqondiso ukusuka ekupheleni kokuthumela ukuya ekupheleni kokufumana. Ngokwamajelo osasazo osasazo ahlukeneyo, amajelo angohlulwa abe ngamacandelo amabini: iitshaneli ezingenazingcingo kunye ne-wireless cha...

1. Ihlelwa ngokwenkonzo yonxibelelwano Ngokweentlobo ngeentlobo zeenkonzo zonxibelelwano, iinkqubo zonxibelelwano zinokwahlulwa zibe ziinkqubo zonxibelelwano ngetelegraph, iinkqubo zonxibelelwano ngomnxeba, iinkqubo zonxibelelwano lwedatha, iinkqubo zonxibelelwano ngemifanekiso, njl.

(1) Ukukhowudwa komthombo kunye nokuguqula iikhowudi Imisebenzi emibini esisiseko: enye kukuphucula ukusebenza kakuhle kokuhanjiswa kolwazi, oko kukuthi, ngokusebenzisa uhlobo oluthile lobugcisa bokufaka ikhowudi yokuzama ukunciphisa inani leesimboli ukunciphisa izinga lesimboli. Okwesibini kukugqiba i-analog/digital (A/D) con...

Zombini umqondiso kunye nengxolo kunxibelelwano zingathathwa njengeenkqubo ezizenzekelayo eziguqukayo kunye nexesha. Inkqubo engaqhelekanga ineempawu zokuguquguquka okungahleliwe kunye nomsebenzi wexesha, onokuchazwa kwiimbono ezimbini ezahlukeneyo kodwa ezinxulumene ngokusondeleyo: (1) Inkqubo engaqhelekanga i...

Imo yonxibelelwano ibhekisa kwimowudi yokusebenza okanye imowudi yokuhanjiswa komqondiso phakathi kwamaqela amabini onxibelelwano. 1. I-Simplex, i-half-duplex, kunye ne-full-duplex yonxibelelwano Kunxibelelwano lwe-point-to-point, ngokwesikhokelo kunye nexesha lokuhanjiswa komyalezo, ...
