Ukubalwa Kokukhanya: Uchungechunge lokuhlinzekwa kwemboni yezokuxhumana kwe-optical yomhlaba wonke lungahlukaniswa kabili
Ezinsukwini ezimbalwa ezedlule, i-LightCounting ikhiphe umbiko wayo wakamuva ngesimo semboni yezokuxhumana kwe-optical. Le nhlangano ikholelwa ukuthi uchungechunge lokuhlinzekwa kwemboni yezokuxhumana kwe-optical yomhlaba wonke lungahlukaniswa kabili, futhi iningi lokukhiqiza lizokwenziwa ngaphandle kweShayina kanye ne-Unite...Funda kabanzi -
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
