Kulesi sihloko sizokwazi ukuthi iyini i-IPTV izici zayo kanye nezinzuzo zayo. I-IPTV iwumabonakude wenethiwekhi osebenzisanayo, okuwubuchwepheshe obusha sha obusebenzisa inethiwekhi ye-Broadband cable TV futhi obuhlanganisa ubuchwepheshe obuhlukahlukene njenge-inthanethi, i-multimedia, kanye nezokuxhumana...

Ezinsukwini zanamuhla, ngokusebenza kahle okuqhubekayo nokuthuthukiswa kwamamojula we-fiber optical, i-PON (i-passive optical fiber network) isiyindlela ebalulekile yokuthwala izinsizakalo zenethiwekhi yokufinyelela kwe-broadband. I-PON ihlukaniswe i-GPON ne-EPON. I-GPON ingashiwo ukuthi iyinguqulo ethuthukisiwe ye-EPON. Lesi sihloko, etu-l...

Ngokuthuthukiswa kwesistimu yokuxhumana ye-optical enebanga elide, umthamo omkhulu kanye nesivinini esiphezulu, ikakhulukazi uma izinga elilodwa lamagagasi lishintsha ukusuka ku-40g kuya ku-100g noma ngisho ne-super 100g, ukuhlakazeka kwe-chromatic, umphumela ongaqondile, ukuhlakazeka kwemodi ye-polarization kanye neminye imiphumela yokudlulisela ekukhetheni. .

Isandulelo esithi FTTH sisho ifayibha ekhaya futhi ngokuqondile kumatheminali abasebenzisi. Lobu futhi ubuchwepheshe ebesibuphishekela futhi sibuhlola iminyaka engaphezu kwengama-20. Ngenxa yokuphumelela okuqhubekayo kwezindleko, ubuchwepheshe, isidingo nokunye, lobu buchwepheshe buye bakhuthazwa futhi bathuthukiswa kabanzi. Kwabezindaba...

I-1) Isandulelo: Ngokuvela okusheshayo kwamabhizinisi ahlukahlukene, izimboni ezengeziwe ziyaqaphela ukuthi kuyadingeka ukugqekeza "ibhodlela" le-bandwidth ngokushesha ngangokunokwenzeka, futhi i-optical fiber iyindlela engcono kakhulu yokudlulisa. I-Optical fiber inezinzuzo ezimbili ngaphezu kwe ...

Umsebenzi wokubuka izibalo zomlayezo: faka "isikhombikubona sombukiso" kumyalo ukuze ubuke amaphakethe angalungile ngaphakathi nangaphandle kwechweba, bese wenza izibalo zokunquma ukukhula kwevolumu, ukuze wahlulele inkinga yephutha. 1) Okokuqala, i-CEC, ifreyimu, namaphakethe wephutha we-throttles avela ku-t...
