Isimo Semboni Yamanje: Ezokuthutha Okubonakalayo Imishini Yezinhlelo ze-DWDM
"Ukuncintisana kakhulu" kuyindlela engcono kakhulu yokuchaza imakethe yemishini ye-Optical Transport DWDM. Nakuba kuyimakethe enkulu, enesisindo esingamaRandi ayizigidi eziyizinkulungwane ezingu-15, kunabakhiqizi bezinhlelo abangaba ngu-20 abahlanganyela ngenkuthalo ekuthengiseni imishini ye-DWDM futhi bancintisana ngamandla ukuthola isabelo semakethe. Lokho kusho ukuthi,...Funda kabanzi -
Ukuqaphela kuka-Omdia: Abasebenzi benethiwekhi encane ye-optical baseBrithani naseMelika bakhuthaza ukukhula okusha kwe-FTTP.
Izindaba ngomhlaka-13 (i-Ace) Umbiko wakamuva ovela enkampanini yocwaningo lwemakethe i-Omida ukhombisa ukuthi eminye imindeni yaseBrithani naseMelika izuza ezinsizakalweni ze-FTTP broadband ezinikezwa ngabasebenzi abancane (kunokuba ngabasebenzi bezokuxhumana abasunguliwe noma abaqhubi be-cable TV). Iningi lalaba basebenzi abancane ...Funda kabanzi -
I-CFP/CFP2/CFP4 Optical Module
I-CFP MSA iyindinganiso yokuqala embonini yokusekela ama-transceivers e-optical e-40 kanye ne-100Gbe Ethernet. Iphrothokholi yemithombo eminingi ye-CFP iwukuchaza imininingwane yokupakisha yamamojula e-optical angashintshwa ashisayo ukukhuthaza izinhlelo zokusebenza ze-40 kanye ne-100Gbit/s, kufaka phakathi uhlelo lokusebenza lwe-Ethernet olusheshayo lwesizukulwane esilandelayo...Funda kabanzi -
Umehluko phakathi kwe-CWDM ne-DWDM
Ngokuthuthuka okuqhubekayo komkhakha wokuxhumana kwe-optical, ubuchwepheshe obusha kanye nezixazululo zokonga izindleko ziyaqhubeka nokutholwa. Isibonelo, imikhiqizo ye-CWDM kanye ne-DWDM isetshenziswa kabanzi, ngakho-ke namuhla sizofunda ngemikhiqizo ye-CWDM kanye ne-DWDM! I-CWDM iwubuchwepheshe bokudlulisa i-WDM obungabizi kakhulu...Funda kabanzi -
Kuyini i-xPON
Njengesizukulwane esisha sobuchwepheshe bokufinyelela i-optical fiber, i-XPON inezinzuzo ezinkulu ekulweni nokuphazamiseka, izici ze-bandwidth, ibanga lokufinyelela, ukugcinwa kanye nokuphathwa, njll. Ukusetshenziswa kwayo kudonsele ukunaka okukhulu kubasebenzisi bomhlaba wonke. Ubuchwepheshe bokufinyelela i-optical be-XPON bucishe bufane...Funda kabanzi -
Umehluko phakathi kwamamojula amane e-optical e-100G QSFP28
1. Izindlela ezahlukene zokudlulisa imojuli ye-optical ye-100G QSFP28 SR4 kanye nemojuli ye-optical ye-100G QSFP28 PSM4 zombili zisebenzisa isikhombimsebenzisi se-MTP esineziteshi eziyi-12, futhi zikwazi ukudlulisa i-100G eneziteshi eziyi-8 ngesikhathi esisodwa. Imojuli ye-optical ye-100G QSFP28 LR4 kanye nemojuli ye-optical ye-100G QSFP28 CWDM4...Funda kabanzi -
Umehluko phakathi kwe-2.4GHz ne-5GHz
Okokuqala, kufanele sicacise ukuthi ukuxhumana kwe-5G akufani ne-5Ghz Wi-Fi esizokhuluma ngayo namuhla. Ukuxhumana kwe-5G empeleni kuyisifinyezo samanethiwekhi eselula esizukulwane sesi-5, okubhekisela kakhulu kubuchwepheshe bokuxhumana beselula. Futhi i-5G yethu lapha ibhekisela...Funda kabanzi -
Umehluko wamaswishi
Izinkinobho zendabuko zakhiwe ngamabhuloho futhi zazingezendlalelo zesibili ze-OSI, imishini yesendlalelo sesixhumanisi sedatha. Ikheli layo lihambisana nekheli le-MAC, ikhethe umzila odlula etafuleni lesiteshi, futhi ukusungulwa nokugcinwa kwetafula lesiteshi kwenziwa ngokuzenzakalelayo yi-C...Funda kabanzi -
Ukuhlaziywa kwamasu kobuchwepheshe be-FTTH
Ngokusho kwedatha efanele, inani labasebenzisi be-broadband be-FTTH/FTTP/FTTB emhlabeni wonke lizofinyelela ku-59% ngo-2025. Imininingwane enikezwe yinkampani yocwaningo lwemakethe i-Point Topic ikhombisa ukuthi lo mkhuba wokuthuthukiswa uzoba ngaphezulu ngo-11% kunezinga lamanje. I-Point Topic ibikezela ukuthi kuzoba nezigidigidi eziyi-1.2 ze-b...Funda kabanzi -
I-FTTR ihola “inguquko” yesibili yokuguqulwa kokukhanya
Njengoba i-“Gigabit Optical Network” ibhalwe embikweni womsebenzi kahulumeni okokuqala, kanye nezidingo zabathengi ezikhulayo zekhwalithi yokuxhumeka, “inguquko” yesibili yokuguqulwa kwe-optical emlandweni we-broadband yezwe lami iyaqalwa. Ku...Funda kabanzi -
