Uyini umehluko phakathi kwe-ONU evamile ne-ONU esekela i-PoE?
Abasebenzi bezokuphepha abenze inethiwekhi ye-PON bayazi nge-ONU, okuyidivayisi yokufinyelela esetshenziswa kunethiwekhi ye-PON, okulingana nokushintsha kokufinyelela kunethiwekhi yethu evamile. Inethiwekhi ye-PON iyinethiwekhi ye-optical engasebenzi. Isizathu sokuthi kuthiwa ayisebenzi ukuthi i-optical fiber iyashintsha...Funda kabanzi -
Ithemba lokuthuthukiswa koshintsho
Ngokuthuthuka okusheshayo kobuchwepheshe be-cloud computing kanye ne-virtualization, ukuhlanganiswa kwezinsizakalo zesikhungo sedatha kubeke phambili izidingo eziphakeme zokusebenza, imisebenzi, kanye nokuthembeka kwamaswishi. Kodwa-ke, ngenxa yokuthi amaswishi esikhungo sedatha angathwala izinsizakalo ezahlukahlukene, ukudluliselwa kwedatha...Funda kabanzi -
Ukuthengwa okuhlanganisiwe kwemishini ye-PON yeselula yaseShayina: imishini ye-OLT engu-3269
I-China Mobile imemezele ukuthengwa kwemishini ye-PON okuhlanganisiwe kusukela ngo-2022 kuya ku-2023 - uhlu lwabaphakeli bemishini abavela emthonjeni owodwa, okuhlanganisa: i-ZTE, i-Fiberhome kanye ne-Shanghai Nokia Bell. Ngaphambilini, i-China Mobile ikhiphe ukuthengwa kwemishini ye-PON ka-2022-2023 okuhlanganisiwe okusha ...Funda kabanzi -
Yini okufanele ngiyenze uma i-transceiver ye-fiber optic iphahlazeka?
Ama-transceiver e-optical fiber ngokuvamile asetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingenakumbozwa khona futhi ama-optical fiber kumele asetshenziswe ukwandisa ibanga lokudlulisela. Ngesikhathi esifanayo, nawo adlale indima enkulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-optical fiber ...Funda kabanzi -
I-PON: Qonda i-OLT, i-ONU, i-ONT ne-ODN
Eminyakeni yamuva nje, i-fiber to the home (FTTH) isiqalile ukwaziswa yizinkampani zokuxhumana emhlabeni wonke, futhi ubuchwepheshe obuvumelayo buthuthuka ngokushesha. Kunezinhlobo ezimbili ezibalulekile zesistimu yokuxhumana kwe-FTTH broadband. Lezi yi-Active Optical Network (AON) kanye ne-Passive Optical Netwo...Funda kabanzi -
Ama-switch VLAN ahlukaniswe kanjani?
1. Hlukanisa i-VLAN ngokwe-port: Abathengisi abaningi benethiwekhi basebenzisa ama-switch port ukuhlukanisa amalungu e-VLAN. Njengoba igama lisikisela, ukuhlukanisa i-VLAN ngokusekelwe kuma-ports ukuchaza ama-port athile e-switch njenge-VLAN. Ubuchwepheshe be-VLAN besizukulwane sokuqala busekela kuphela ukuhlukaniswa kwama-VLAN kuma-port amaningi e-...Funda kabanzi -
Ingabe imodemu ye-optical ixhunywe kuswishi noma ku-router kuqala?
Xhuma i-router kuqala. I-modem ye-optical ixhunywe ku-router kuqala bese kuba ku-switch, ngoba i-router idinga ukwabela i-ip, futhi i-switch ayikwazi, ngakho-ke kumele ibekwe ngemuva kwe-router. Uma kudingeka ukuqinisekiswa kwephasiwedi, vele, xhuma kuqala echwebeni le-WAN le-ro...Funda kabanzi -
Ukubuka konke kanye nemisebenzi yamaswishi okukhanya
Ukubuka Konke Kokushintsha Kokukhanya: i-fiber optic switch iyidivayisi yokudlulisa ukudlulisa kwenethiwekhi ngesivinini esikhulu. Uma iqhathaniswa nezinkinobho ezijwayelekile, isebenzisa izintambo ze-fiber optic njengendlela yokudlulisa. Izinzuzo zokudlulisa i-fiber optic yisivinini esisheshayo kanye nekhono eliqinile lokuvimbela ukuphazamiseka. I-Fibre Channe...Funda kabanzi -
Amaphutha ayisithupha avamile e-fiber optic transceivers
I-Fiber optic transceiver iyiyunithi yokuguqula imidiya yokudlulisa ye-Ethernet eshintshana ngezibonakaliso zikagesi ezisontekile ezikude kanye nezibonakaliso ze-optical ezikude. Ibizwa nangokuthi i-photoelectric converter (i-Fiber Converter) ezindaweni eziningi. 1. Isibani se-Link asikhanyisi (1) C...Funda kabanzi -
Umehluko phakathi kweswishi ne-router
(1) Kusukela ekubukekeni, sihlukanisa phakathi kwama-Switch amabili ngokuvamile anezimbobo eziningi futhi abukeka elukhuni. Izimbobo ze-router zincane kakhulu futhi ivolumu incane kakhulu. Eqinisweni, isithombe ngakwesokudla akuyona i-router yangempela kodwa sihlanganisa umsebenzi we-router. Ngaphezu kwe-fu...Funda kabanzi -
Yimuphi umshini we-ONU ongcono ohlelweni lokuqapha?
Kulezi zinsuku, emadolobheni omphakathi, amakhamera okuqapha afakwa kuwo wonke amakhona.
