Umehluko phakathi kwe-OLT, i-ONU, irutha nokushintsha
Okokuqala, i-OLT iyitheminali yomugqa obonakalayo, futhi i-ONU iyiyunithi yenethiwekhi yokubona (ONU).Zombili ziyimishini yokuxhuma inethiwekhi yokudlulisa amehlo.Kungamamojula amabili adingekayo ku-PON: I-PON (Inethiwekhi Yokungaboni ngaso linye: Inethiwekhi ye-Passive Optical).I-PON (inethiwekhi ye-passive optical) isho ukuthi (...Funda kabanzi -
Ingabe ukhona umehluko phakathi kwe-FTTB ne-FTTH?
1. Imishini ehlukene Uma i-FTTB ifakiwe, kudingeka okokusebenza kwe-ONU;Impahla ye-FTTH ye-ONU ifakwe ebhokisini engxenyeni ethile yesakhiwo, futhi umshini ofakiwe womsebenzisi uxhunywe ekamelweni lomsebenzisi ngezintambo zeSigaba 5.2. Umthamo ofakiwe ohlukile I-FTTB iyi-fiber optic...Funda kabanzi -
Hlaziya izidingo ezine ezinkulu zezikhungo zedatha zamamojula optical
Njengamanje, ithrafikhi yesikhungo sedatha ikhula ngokuqhubekayo, futhi umkhawulokudonsa wenethiwekhi uhlala uthuthukiswa, okuletha amathuba amahle okuthuthukiswa kwamamojula we-high-speed optical.Ake ngikhulume nawe ngezimfuneko ezine ezinkulu zesikhungo sedatha yesizukulwane esilandelayo...Funda kabanzi -
I-LightCounting: Uchungechunge lokuhlinzeka ngemboni yezokuxhumana emhlabeni wonke lungahlukaniswa kabili
Ezinsukwini ezimbalwa ezedlule, i-LightCounting ikhiphe umbiko wayo wakamuva mayelana nesimo somkhakha wezokuxhumana optical.Le nhlangano ikholelwa ukuthi uchungechunge lokuhlinzekwa kwemboni yezokuxhumana emhlabeni wonke lungahlukaniswa kabili, futhi ukukhiqizwa okuningi kuzokwenziwa ngaphandle kweChina kanye ne-Unite...Funda kabanzi -
Isimo Samanje Semboni: Izinsiza Zesistimu Yezokuthutha ze-DWDM
"Ukuncintisana kakhulu" kuyindlela engcono kakhulu yokuveza imakethe yemishini ye-Optical Transport DWDM.Nakuba iyimakethe enkulu, enesisindo esingamaRandi ayizigidi eziyizinkulungwane ezingu-15, kukhona abakhiqizi bezinhlelo abangaba ngu-20 ababamba iqhaza elibonakalayo ekuthengiseni imishini ye-DWDM futhi balwela ukwabelana ngemakethe.Lokho kusho,...Funda kabanzi -
Ukubuka kwe-Omdia: Opharetha benethiwekhi encane yaseBrithani neMelika baphromotha i-boom entsha ye-FTTP.
Izindaba zangomhla ziyi-13 (Ace) Umbiko wakamuva ovela enkampanini yocwaningo lwemakethe i-Omida ubonisa ukuthi eminye imizi yaseBrithani neyaseMelika iyazuza kumasevisi e-broadband e-FTTP ahlinzekwa o-opharetha abancane (kunokuba abaqhubi bezingcingo ezimisiwe noma ama-opharetha we-TV yekhebula).Abaningi balaba opharetha abancane ...Funda kabanzi -
