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 -
Kuyini i-AOC
Ikhebula le-AOC Active Optical, elaziwa nangokuthi amakhebula e-Active Optical, libhekisela kumakhebula okuxhumana adinga amandla angaphandle ukuguqula amasignali kagesi abe amasignali okukhanya noma amasignali okukhanya abe amasignali kagesi. Ama-transceiver okukhanya kuzo zombili izinhlangothi zekhebula ahlinzeka ngokuguqulwa kwe-photoelectric...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. Ubuchwepheshe be-fiber optic transceiver bushintsha ngokushesha ukuze kuhlangatshezwane nezidingo ezikhulayo zesivinini kanye nomthamo. Ake sibheke ukuthi lokhu kuthuthuka kuzothinta kanjani...Funda kabanzi -
Uyini umehluko phakathi kwama-transceivers e-fiber optic nama-transceivers e-Ethernet?
Ama-transceiver e-FC (Fibre Channel) ayingxenye ebalulekile yengqalasizinda ye-Fibre Channel, futhi ama-transceiver e-Ethernet ahlanganiswe nama-switch e-Ethernet ayinhlanganisela ethandwayo yokufanisa lapho kusetshenziswa i-Ethernet. Ngokusobala, lezi zinhlobo ezimbili zama-transceiver zisebenza ngezinhlelo zokusebenza ezahlukene, kodwa yini ngempela...Funda kabanzi -
Umehluko phakathi kwamaswishi e-fiber optic nama-transceivers e-fiber optic!
Ama-transceiver e-optical nama-switch womabili abalulekile ekudlulisweni kwe-Ethernet, kodwa ahlukile ngokusebenza kanye nokusetshenziswa. Ngakho-ke, uyini umehluko phakathi kwama-transceiver e-fiber optic nama-switch? Uyini umehluko phakathi kwama-transceiver e-fiber optic nama-switch? I-transceiver ye-fiber optic iyi...Funda kabanzi -
Ungawahlola kanjani ama-transceivers e-fiber optic?
Ngokuthuthuka kwenethiwekhi kanye nokuthuthuka kobuchwepheshe, abakhiqizi abaningi bezingxenye ze-fiber optic bavele emakethe, bezama ukuthola ingxenye yomhlaba wenethiwekhi. Njengoba laba bakhiqizi bekhiqiza izingxenye ezahlukahlukene, umgomo wabo ukwenza ikhwalithi ephezulu futhi ivumelane...Funda kabanzi -
Izinsiza zokusekela ama-transceiver e-fiber optic: Izisekelo ze-Optical Distribution Frame (ODF)
Ukufakwa kwe-fiber optics kuye kwanda, kuqhutshwa isidingo samazinga edatha asheshayo. Njengoba i-fiber efakiwe ikhula, ukuphathwa kwamanethiwekhi okuthutha kwe-optical kuba nzima kakhulu. Kunezinto eziningi okufanele zicatshangelwe ngesikhathi sokufakwa kwezintambo ze-fiber, njengokuguquguquka, ukwenzeka kwesikhathi esizayo, ukuthunyelwa...Funda kabanzi -
