Iqhaza elibalulekile lokuhlola ukuhlakazeka ekuhlonzeni i-fiber
Ukuthi ukuxhumanisa imiphakathi noma amazwekazi adlulayo, isivinini nokunemba kuyizimfuneko ezimbili ezibalulekile zamanethiwekhi e-fiber optic aphatha ukuxhumana kwemisebenzi ebalulekile. Abasebenzisi badinga izixhumanisi ezisheshayo ze-FTTH kanye noxhumo lweselula lwe-5G ukuze bathole i-telemedicine, imoto ezimele, inkomfa ngevidiyo nezinye izinhlelo zokusebenza ezijulile zomkhawulokudonsa. Ngokuvela kwenani elikhulu lezikhungo zedatha kanye ne-rap...Funda kabanzi -
Ukuhlaziywa kochungechunge lwentambo ye-coaxial ye-LMR ngayinye ngayinye
Uma uke wasebenzisa ukuxhumana kwe-RF (ifrikhwensi yomsakazo), amanethiwekhi weselula, noma amasistimu e-antenna, ungase uhlangane negama elithi ikhebula le-LMR. Kodwa liyini ngempela futhi kungani lisetshenziswa kabanzi kangaka? Kulesi sihloko, sizohlola ukuthi iyini ikhebula le-LMR, izici zayo ezibalulekile, nokuthi kungani kuyisinqumo esikhethwayo sezinhlelo ze-RF, bese siphendula umbuzo othi 'Iyini ikhebula le-LMR?'.

Umehluko phakathi kwe-fiber optical engabonakali kanye ne-fiber optical evamile
Emkhakheni wezokuxhumana kanye nokudluliswa kwedatha, ubuchwepheshe be-fiber optic buye benza izinguquko endleleni esixhuma ngayo nesixhumana ngayo. Phakathi kwezinhlobo ezihlukahlukene ze-optical fibers, izigaba ezimbili ezivelele ziye zavela: i-fiber optical evamile kanye ne-fiber optical engabonakali. Nakuba inhloso eyisisekelo yakho kokubili iwukudlulisa idatha ngokukhanya, izakhiwo, izinhlelo zokusebenza, kanye ne-pe...Funda kabanzi -
