Ukusebenza kwamanje kwenethiwekhi ye-DCI (Ingxenye Yokuqala)
Ngemva kokuba inethiwekhi ye-DCI yethule ubuchwepheshe be-OTN, kufana nokwengeza umsebenzi wonke owawungekho ngaphambili maqondana nokusebenza. Inethiwekhi yesikhungo sedatha yendabuko iyinethiwekhi ye-IP, engeyezobuchwepheshe benethiwekhi enengqondo. I-OTN ku-DCI ubuchwepheshe bezendlalelo ezibonakalayo, ...Funda kabanzi -
Kuyini i-DCI Box
Umsuka wenethiwekhi ye-DCI Ekuqaleni, isikhungo sedatha sasilula, sinamakhabethe ambalwa + ama-air conditioner ambalwa ane-P ephezulu ekamelweni elingahleliwe, bese kuba namandla edolobha elilodwa + ama-UPS ambalwa, futhi saba isikhungo sedatha. Kodwa-ke, lolu hlobo lwesikhungo sedatha sincane kakhulu futhi siphansi ngokwethembekile...Funda kabanzi -
Inzuzo ye-WIFI 6 ONT
Uma kuqhathaniswa nezizukulwane zangaphambilini zobuchwepheshe be-WiFi, izici eziyinhloko zesizukulwane esisha se-WiFi 6 yilezi: Uma kuqhathaniswa nesizukulwane sangaphambilini se-802.11ac WiFi 5, izinga eliphezulu lokudluliswa kwe-WiFi 6 likhushulwe lisuka ku-3.5Gbps langaphambili laya ku-9.6Gbps, futhi ijubane lethiyori li...Funda kabanzi -
Ingabe kukhona amamojula optical e-QSFP28?
I-QSFP28 optical module ingathiwa iyisizukulwane esisha se-optical module, ethandwa abakhiqizi abaningi ngenxa yezinzuzo zayo njengosayizi omncane, ukuminyana kwe-port ephezulu, kanye nokusetshenziswa kwamandla aphansi. Ngakho-ke, yiziphi izinhlobo zama-QSFP8 optical module akhona? I-QSFP28 optical module yaziwa nangokuthi...Funda kabanzi -
Izimo zohlelo lokusebenza lwe-OTN
I-OTN ne-PTN Kufanele kushiwo ukuthi i-OTN ne-PTN ubuchwepheshe obubili obuhlukene ngokuphelele, futhi uma sikhuluma ngobuchwepheshe, kufanele kushiwo ukuthi akukho ukuxhumana. I-OTN iyinethiwekhi yezokuthutha ebonakalayo, ethuthukiswe kusukela kubuchwepheshe bendabuko bokuhlukanisa ubude be-wavelength. Ngokuyinhloko yengeza ubuhlakani...Funda kabanzi -
I-OTN (i-Optical Transport Network) iyinethiwekhi yokudlulisa ehlela amanethiwekhi kungqimba lwe-optical ngokusekelwe kubuchwepheshe be-multiplexing division wavelength.
Yinethiwekhi yokudlulisa umgogodla wesizukulwane esilandelayo. Kalula nje, iyinethiwekhi yokuthutha yesizukulwane esilandelayo esekelwe kubude be-wavelength. I-OTN iyinethiwekhi yokuthutha esekelwe kubuchwepheshe bokuphindaphindwa kwe-wavelength division ehlela inethiwekhi kungqimba olubonakalayo, futhi iyinethiwekhi yokuthutha umgogodla...Funda kabanzi -
Umehluko phakathi kwe-DWDM ne-OTN
I-DWDM kanye ne-OTN ziyizinhlelo ezimbili zobuchwepheshe ezakhiwe ubuchwepheshe bokudlulisa ukuhlukaniswa kwe-wavelength eminyakeni yamuva nje: I-DWDM ingabhekwa njenge-PDH yangaphambilini (ukudluliselwa kwe-point-to-point), kanti izinsizakalo eziku-inthanethi nezingaxhunyiwe ku-inthanethi ziqedwa ku-ODF ngama-hard jumpers; I-OTN ifana ne-SDH (izinhlobo ezahlukene...Funda kabanzi -
Ukuhlukaniswa kwekhebula elisheshayo le-DAC elivamile
Ikhebula le-DAC elisheshayo (Ikhebula Elinamathisela Ngokuqondile) ngokuvamile lihunyushwa ngokuthi ikhebula eliqondile, ikhebula lethusi elixhuma ngqo noma ikhebula lesivinini esikhulu. Lichazwa njengohlelo lokuxhuma ibanga elifushane olungabizi kakhulu oluthatha indawo yamamojula e-optical. Zombili iziphetho zekhebula lesivinini esikhulu zinamamojula Ukuhlanganiswa kwekhebula, okungamele...Funda kabanzi -
Ukuhlaziywa okujulile kwama-transceivers e-fiber optic
Ngenxa yobubanzi be-bandwidth obuphezulu kanye nokuncipha okuphansi okulethwa yi-optical fiber, ijubane lenethiwekhi lithatha igxathu elikhulu.
