Yini okufanele ngiyenze uma i-fiber optic transceiver iphahlazeka?
Ama-transceivers e-fiber optical ngokuvamile asetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela.Ngasikhathi sinye, baphinde babamba iqhaza elikhulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optical ...Funda kabanzi -
I-PON: Qonda i-OLT, i-ONU, i-ONT ne-ODN
Eminyakeni yamuva nje, i-fiber to the home (FTTH) isiqalile ukuba yigugu izinkampani zokuxhumana emhlabeni wonke, futhi ubuchwepheshe obuvumelayo buthuthuka ngokushesha.Kunezinhlobo ezimbili zesistimu ezibalulekile zokuxhunywa kwe-broadband ye-FTTH.Lezi yi-Active Optical Network (AON) kanye ne-Passive Optical Network...Funda kabanzi -
Ahlukaniswa kanjani ama-switch VLAN?
1. Hlukanisa i-VLAN ngokusho kwechweba: Abathengisi abaningi benethiwekhi basebenzisa izimbobo zokushintsha ukuze bahlukanise amalungu e-VLAN.Njengoba igama liphakamisa, ukuhlukanisa i-VLAN ngokusekelwe kumachweba ukuchaza izimbobo ezithile zokushintsha njenge-VLAN.Ubuchwepheshe be-VLAN besizukulwane sokuqala busekela kuphela ukuhlukaniswa kwama-VLAN kumachweba amaningi we...Funda kabanzi -
Ingabe imodemu yokubona ixhunywe kusiwishi noma kumzila kuqala
Xhuma irutha kuqala.Imodemu ye-optical ixhunywe ku-router kuqala bese ishintsha, ngoba i-router idinga ukwaba i-ip, futhi inkinobho ayikwazi, ngakho-ke kufanele ibekwe ngemuva komzila.Uma ukuqinisekiswa kwephasiwedi kudingekile, vele, qala ngokuxhuma embobeni ye-WAN ye-ro...Funda kabanzi -
Uhlolojikelele kanye nemisebenzi yokushintsha optical
Uhlolojikelele lwe-Optical Switch: i-fiber optic switch iyithuluzi lokudlulisa inethiwekhi elinesivinini esikhulu.Uma kuqhathaniswa namaswishi ajwayelekile, isebenzisa izintambo ze-fiber optic njengendawo yokudlulisela.Izinzuzo zokudluliswa kwe-fiber optical isivinini esisheshayo nekhono eliqinile lokulwa nokuphazamiseka.I-Fiber Channe...Funda kabanzi -
Amaphutha ayisithupha ajwayelekile ama-fiber optic transceivers
I-Fiber optic transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasignali kagesi asontekile amabanga amafushane kanye namasignali okubona amabanga amade.Ibizwa nangokuthi i-photoelectric converter (I-Fiber Converter) ezindaweni eziningi.1.
