Izici ze-OSI Physical Layer
Isendlalelo esibonakalayo singezansi kwemodeli ye-OSI, futhi umsebenzi waso oyinhloko ukusebenzisa isikhungo sokudlulisa esingokoqobo ukuze sinikeze uxhumano oluphathekayo lwesendlalelo sesixhumanisi sedatha ukuze sidlulise ukusakaza okuncane. Isendlalelo esibonakalayo sichaza ukuthi intambo ixhunywe kanjani kunethiwekhi c...Funda kabanzi - Ngu-Admin / 28 Jul 22 /0Amazwana
I-Electric Port Module kanye Nomehluko we-Optical Port Module
Abantu abaningi abacaci kahle mayelana namamojula we-port kagesi, noma bavame ukudideka namamojula optical, futhi abakwazi ukukhetha amamojula embobo kagesi ngendlela efanele ukuze bahlangabezane nenzuzo efanayo yezidingo zebanga lokudlulisela kanye nokwenza ngcono izindleko. Ngakho-ke, kulobu buciko ...Funda kabanzi

Iyini i-IPTV? Yini I-IPTV Izici Nezinzuzo?
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...Funda kabanzi - Ngu-Admin / 26 Jul 22 /0Amazwana
Ulwazi Oluyisisekelo Mayelana ne-GPON optical module
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...Funda kabanzi - Ngu-Admin / 25 Jul 22 /0Amazwana
Umsebenzi we-Optical module FEC
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. .Funda kabanzi - Ngu-Admin / 22 Jul 22 /0Amazwana
Inhlangano yokusebenza ye-GPON FTTx
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...Funda kabanzi
