Uhlelo lwe-PON lusebenzisa ubuchwepheshe bokuhlukanisa isikhathi sokuphindaphinda ekuqondeni kwe-uplink, futhi i-ONU ithumela ama-datagrams ekuqondeni kwe-uplink ngokuvumelana nesitembu sesikhathi esinikezwe i-OLT. Uma i-ONU ikhipha ukukhanya ngaphandle kokunikeza isitembu sesikhathi, izongqubuzana nezimpawu zokukhishwa kwezinye ku...

Ngokuthuthukiswa kwezinhlelo zokuxhumana ezibonakalayo ezinebanga elide, umthamo omkhulu, kanye nesivinini esiphezulu, ikakhulukazi uma izinga legagasi elilodwa lishintsha ukusuka ku-40g kuya ku-100g noma ngisho ne-super 100g, ukuhlakazeka kwe-chromatic, imiphumela engaqondile, ukuhlakazeka kwemodi ye-polarization, neminye imiphumela yokudlulisela ku. ..

Ikhodi yokuthola iphutha (ikhodi yokuhlola ukulinganiswa): ikhodi yokuhlola ukulinganiswa iqukethe iyunithi yolwazi yebhithi elingu-n-1 kanye nesici sokuhlola esingu-1 bit. Iyunithi yolwazi lwebhithi ye-N-1 yidatha evumelekile kulwazi esiluthumelayo, futhi iyunithi yokuhlola ye-1-bit isetshenziselwa ukutholwa kwamaphutha kanye nekhodi yokuphinda isetshenziswe. Ukuhlola okungavamile: uma i-n...

Sawubona, Bafundi. Kulesi sihloko ngizoxoxa nge-OSI-Data Link Layer Error Control ngencazelo. Masiqale… Ukuze siqonde ukudluliswa kwesendlalelo sesixhumanisi sedatha ake sithathe isibonelo, uma idivayisi engu-A idinga ukuxhumana nedivayisi engu-B, isixhumanisi sokuxhumana ...

Sawubona Bafundi, Kulesi sihloko sizofunda ukuthi yini Ukulawula Amaphutha kanye nokuhlelwa kokulawula amaphutha. Enqubweni yokudluliswa kwedatha, ngenxa yethonya lomsindo esiteshini, i-waveform yesiginali ingase ihlanekezelwe lapho idluliselwa kumamukeli, kabusha...

Ohlelweni lokuxhumana lwe-digital division multiplexing zokuxhumana, ukuze kuhlukaniswe kahle amasiginali wesikhathi, isiphetho sokuthumela kufanele sinikeze uphawu lokuqala lohlaka ngalunye, futhi inqubo yokuthola nokuthola lolu phawu ekugcineni ibizwa ngokuthi ukuvumelanisa ifremu. .
