Okuqukethwe okulandelayo ulwazi olufanele lwe-switch optical port kanye ne-electrical port ehlungwe ...Funda kabanzi -
Iyiphi idivayisi ye-ONU engcono kakhulu ohlelweni lokuqapha?
Kulezi zinsuku, emadolobheni omphakathi, amakhamera okuqapha afakwa kuwo wonke amakhona. Sibona amakhamera ahlukahlukene okuqapha ezakhiweni eziningi zokuhlala, ezakhiweni zamahhovisi, ezitolo ezinkulu, emahhotela nakwezinye izindawo ukuvimbela ukwenzeka kwemisebenzi engekho emthethweni. Ngokuthuthuka okuqhubekayo kwe-ec...Funda kabanzi -
Yini eyenziwa yi-"switch"? kanjani ukuyisebenzisa?
1. Yazi iswishi Kusukela kumsebenzi: iswishi isetshenziselwa ukuxhuma amadivayisi amaningi, ukuze abe nezimo zokusebenzisana kwenethiwekhi. Ngokwencazelo: iswishi iyidivayisi yenethiwekhi engaxhuma amadivayisi amaningi kunethiwekhi yekhompyutha bese idlulisela idatha endaweni oya kuyo ngephakethe...Funda kabanzi -
Asetshenziswa kanjani amaphaneli e-network patch kanye nama-switch?
Ukuxhumana phakathi kwephaneli ye-patch yenethiwekhi kanye neswishi kudinga ukuxhunywa ngekhebula lenethiwekhi. Ikhebula lenethiwekhi lixhuma uhlaka lwe-patch neseva, kanti uhlaka lwe-patch egumbini lokuxhuma izintambo lusebenzisa nekhebula lenethiwekhi ukuze luxhume neswishi. Ngakho-ke uxhuma kanjani? 1.

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
