Umhlahlandlela Wokufaka Esikhundleni we-Huanet OLT Uplink Board GE-10GE
1. Isimo Sokusebenza Njengamanje, inethiwekhi ekhona ihlelwe ngamabhodi e-GICF GE, futhi ukusetshenziswa kwe-bandwidth yamanje ephezulu kuseduze noma kudlula umkhawulo, okungafaneleki ekuhlinzekweni kwensizakalo kamuva; idinga ukushintshwa ngamabhodi aphezulu e-10GE. 2. Izinyathelo zokusebenza...Funda kabanzi -
Indlela yokubhanqa ama-transceivers e-fiber optic
Uma ufuna ukwazi ukuthi ungawabhangqa kanjani futhi uwasebenzise kanjani ama-transceiver e-fiber optic, kufanele uqale wazi ukuthi ama-transceiver e-fiber optic enzani. Kalula nje, umsebenzi wama-transceiver e-fiber optic ukuguqulwa okuhlangene phakathi kwamasignali optical namasignali kagesi. Isignali optical iwukufakwa okuvela ku-optical...Funda kabanzi -
Ukushintshana kwe-switch ngezindlela ezintathu ezilandelayo
1) I-Straight-through: I-switch ye-Ethernet e-straight-through ingaqondwa njenge-line matrix telephone switch ene-crossover phakathi kwama-port. Uma ithola iphakethe ledatha echwebeni lokufaka, ihlola i-packet header yephakethe, ithole ikheli lendawo yephakethe, iqale i-interna...Funda kabanzi -
Ithonya lokukhanya okubuthakathaka kwe-ONU kusivinini senethiwekhi
I-ONU yilokho esivame ukukubiza ngokuthi “ikati elikhanyayo”, ukukhanya okuphansi kwe-ONU kubhekisela esimweni sokuthi amandla okukhanya atholwe yi-ONU angaphansi kokuzwela okwamukelayo kwe-ONU. Ukuzwela okwamukelayo kwe-ONU kubhekisela emandleni amancane okukhanya angatholwa yi-ONU ngesikhathi sokujwayelekile...Funda kabanzi -
Iyini iswishi? Yenzelwe ini?
I-Switch (Switch) isho ukuthi “switch” futhi iyidivayisi yenethiwekhi esetshenziselwa ukudlulisa isignali kagesi (optical). Inganikeza indlela yesignali kagesi ekhethekile yanoma yimaphi ama-node amabili enethiwekhi yeswitch yokufinyelela. Amaswitshi avame kakhulu amaswitshi e-Ethernet. Amanye avamile yi-vo yocingo...Funda kabanzi -
Mangaki ama-ONU i-OLT eyodwa engaxhuma kuwo?
64, ngokuvamile ngaphansi kuka-10. 1. Ngokwethiyori, u-64 ungaxhunywa, kodwa uma ucabangela ukuncishiswa kokukhanya kanye nokuzwela kwe-onu ekukhanyeni, ezisetshenzisweni ezingokoqobo ezijwayelekile, inani lokuxhumeka nge-port ngayinye lingaphansi kuka-10. Inani eliphezulu labasebenzisi abafinyelelwe yi-olt linqunyelwe kakhulu yizintathu...Funda kabanzi -
Ulwazi lwama-switch optical ports kanye nama-electrical ports
Kunezinhlobo ezintathu zamaswishi: ama-port kagesi amsulwa, ama-port optical amsulwa, kanye nama-port kagesi athile kanye nama-port optical. Kunezinhlobo ezimbili kuphela zama-port, ama-port optical kanye nama-port kagesi. 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.
