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.

Umehluko phakathi kweswishi nerutha
(1) Kusukela ekubukekeni, sihlukanisa phakathi kwamaShintshi amabili ngokuvamile anezimbobo eziningi futhi abukeka enzima.Izimbobo zomzila zincane kakhulu futhi ivolumu incane kakhulu.Eqinisweni, isithombe esingakwesokudla akusona i-router yangempela kodwa sihlanganisa umsebenzi we-router.Ngaphezu kwe-fu...Funda kabanzi -
Iyiphi impahla ye-ONU engcono ohlelweni lokuqapha?
Namuhla, emadolobheni omphakathi, amakhamera okuqapha afakwa ngokuyisisekelo kuwo wonke amagumbi.Sizobona amakhamera okuqapha ahlukahlukene ezakhiweni eziningi zokuhlala, ezakhiweni zamahhovisi, ezinxanxatheleni zezitolo, emahhotela nakwezinye izindawo ukuze sinqande ukwenzeka kwemisebenzi engekho emthethweni.Ngokuthuthuka okuqhubekayo ...Funda kabanzi -
Iyini idivayisi ye-ONU?
Iyunithi yenethiwekhi ye-ONU (Optical Network Unit), i-ONU ihlukaniswe yaba iyunithi yenethiwekhi yokubona esebenzayo kanye neyunithi yenethiwekhi ye-passive optical network.Ngokuvamile, amadivaysi afakwe ukuqapha kwenethiwekhi okuhlanganisa abamukeli be-optical, ama-transmitters optical akhuphukayo, nama-amplifiers amaningi amabhuloho abizwa ngokuthi i-optical node...Funda kabanzi -
I-OTN enkathini yenethiwekhi ye-All-Optical 2.0
Indlela yokusebenzisa ukukhanya ukudlulisa ulwazi kungathiwa inomlando omude.I-“Beacon Tower” yesimanje ivumele abantu ukuba bathole ukunethezeka kokudlulisa ulwazi ngokukhanya.Kodwa-ke, le ndlela yokuxhumana ye-primitive optical isemuva kakhulu, inomkhawulo...Funda kabanzi -
Ungahlukanisa kanjani ngokushesha phakathi kokushintsha nama-routers
Iyini irutha?Ama-routers asetshenziswa kakhulu kumanethiwekhi endawo kanye namanethiwekhi endawo ebanzi.Ingakwazi ukuxhuma amanethiwekhi amaningi noma izingxenye zenethiwekhi ukuze “zihumushe” ulwazi lwedatha phakathi kwamanethiwekhi ahlukene noma izingxenye zenethiwekhi, ukuze “bafunde” idatha yomunye nomunye ukuze ...Funda kabanzi -
Yiziphi izinhlobo eziyinhloko zemishini ye-ONU esetshenziswa amaklayenti e-fiber-optic broadband?
1. Izinto ze-ONU ezisetshenziswa iklayenti ngokuyinhloko zimi kanje: 1) Ngokwenombolo yezimbobo ze-LAN, kukhona imbobo eyodwa, izimbobo ezi-4, izimbobo eziyisi-8 kanye nezimbobo eziningi ze-ONU.Imbobo ngayinye ye-LAN ingahlinzeka ngemodi yokubhukha kanye nemodi yomzila ngokulandelanayo.2) Ngokuya ngokuthi inomsebenzi we-WIFI noma cha, inga...Funda kabanzi -
Uyini umehluko phakathi kwe-ONU ejwayelekile kanye ne-ONU esekela i-POE?
Abantu bezokuphepha abake basebenza kumanethiwekhi e-PON ngokuyisisekelo bayayazi i-ONU, okuyisisetshenziswa sokugcina sokufinyelela esisetshenziswa kunethiwekhi ye-PON, elingana neswishi yokufinyelela kunethiwekhi yethu evamile.Inethiwekhi ye-PON iyinethiwekhi yokubona engenzi lutho.Isizathu sokuthi kungani kuthiwa ayisebenzi ukuthi i-optical fibe...Funda kabanzi
