Ukushintshanisa kushintshwa ngezindlela ezintathu ezilandelayo
1) Iqonde ngqo: Iswishi ye-Ethernet eqondile ingaqondwa njengeswishi yocingo ye-matrix ene-crossover phakathi kwamachweba.Lapho ithola iphakethe ledatha embotsheni yokufaka, ihlola unhlokweni wephakethe wephakethe, ithola ikheli lendawo yephakethe, iqala i-interna...Funda kabanzi -
Umthelela wokukhanya okubuthakathaka kwe-ONU kusivinini senethiwekhi
I-ONU yilokho esivame ukukubiza ngokuthi "ikati elikhanyayo", ukukhanya okuphansi kwe-ONU kubhekisela kwinto yokuthi amandla okubona atholwe yi-ONU angaphansi kokuzwela kokuthola kwe-ONU.Ukuzwela kokwamukela kwe-ONU kubhekisela emandleni amancane okubona i-ONU engawathola ngesikhathi se-norma...Funda kabanzi -
Kuyini ukushintsha?Kwenzelweni?
Ukushintsha (Shintsha) kusho “ukushintsha” futhi kuyidivayisi yenethiwekhi esetshenziselwa ukudlulisa isignali kagesi (i-optical).Ingahlinzeka ngendlela yesignali kagesi ekhethekile yanoma yimaphi amanodi enethiwekhi amabili weswishi yokufinyelela.Izinguquko ezivame kakhulu amaswishi e-Ethernet.Ezinye ezijwayelekile ngocingo vo...Funda kabanzi -
Mangaki ama-ONU eyodwa i-OLT engaxhumeka kuwo?
64, ngokuvamile ngaphansi kuka-10. 1. Ngokombono, u-64 angaxhunywa, kodwa uma kucatshangelwa ukuncishiswa kokukhanya kanye nokuzwela kwe-onu ekukhanyeni, ngokujwayelekile ukusetshenziswa okungokoqobo, inani lokuxhuma ngembobo ngayinye lingaphansi kuka-10. Inombolo enkulu wabasebenzisi abafinyelelwe yi-olt ikakhulukazi bakhawulelwe kathathu...Funda kabanzi -
Ulwazi lokushintsha izimbobo zokukhanya nezimbobo zikagesi
Kunezinhlobo ezintathu zokushintsha: izimbobo zikagesi ezimsulwa, izimbobo zokukhanya okumsulwa, nezinye izimbobo zikagesi nezinye izimbobo zokubuka.Kunezinhlobo ezimbili kuphela zamachweba, izimbobo ezibonakalayo nezimbobo zikagesi.Okuqukethwe okulandelayo wulwazi olufanele lokushintshwa kwe-optical port kanye nembobo kagesi ehlelwe ...Funda kabanzi -
Iyiphi idivayisi ye-ONU engcono ohlelweni lokuqapha?
Namuhla, emadolobheni omphakathi, amakhamera okuqapha afakwa ngokuyisisekelo kuwo wonke amagumbi.Sibona amakhamera ahlukahlukene okuqapha ezakhiweni eziningi zokuhlala, ezakhiweni zamahhovisi, ezinxanxatheleni zezitolo, emahhotela nakwezinye izindawo ukuze kuvinjelwe ukwenzeka kwemisebenzi engekho emthethweni.Ngokuthuthuka okuqhubekayo kwe-ec...Funda kabanzi -
Yenzani "ukushintsha"?isetshenziswa kanjani?
1. Yazi iswishi Kuhlelo lokusebenza: inkinobho isetshenziselwa ukuxhuma amadivaysi amaningi, ukuze abe nemibandela yokusebenzisana kwenethiwekhi.Ngencazelo: iswishi iyidivayisi yenethiwekhi engaxhuma amadivayisi amaningi kunethiwekhi yekhompyutha futhi idlulisele idatha endaweni okuyiwa kuyo ngephakethe...Funda kabanzi -
Asetshenziswa kanjani amaphaneli enethiwekhi namaswishi?
Ukuxhumana phakathi kwephaneli yesichibi senethiwekhi kanye neswishi kudinga ukuxhunywa ngentambo yenethiwekhi.Ikhebula lenethiwekhi lixhuma uhlaka lokuchibiyela neseva, futhi ifreyimu yokuchibiyela egunjini lokuhlanganisa izintambo nalo lisebenzisa ikhebula lenethiwekhi ukuze lixhume ngokushintsha.Ngakho uxhuma kanjani?1.

Uyini umehluko phakathi kwe-ONU evamile kanye ne-ONU esekela i-PoE?
Abasebenzi bezokuphepha abenze inethiwekhi ye-PON ngokuyisisekelo bazi nge-ONU, okuyidivayisi yokufinyelela esetshenziswa kunethiwekhi ye-PON, elingana neswishi yokufinyelela kunethiwekhi yethu evamile.Inethiwekhi ye-PON iyinethiwekhi yokubona engenzi lutho.Isizathu sokuthi kungani kuthiwa ayisebenzi ukuthi i-optical fiber tran...Funda kabanzi -
Ithemba lokuthuthukiswa koshintsho
Ngokuthuthuka okusheshayo kobuchwepheshe bekhompuyutha yamafu kanye nokwenza izinto ezibonakalayo, ukuhlanganiswa kwezinsizakalo zesikhungo sedatha kubeke phambili izidingo eziphakeme zokusebenza, imisebenzi, nokuthembeka kwamaswishi.Kodwa-ke, ngenxa yokuthi ukushintshwa kwesikhungo sedatha kungathwala izinsizakalo ezahlukahlukene, i-data transmissi...Funda kabanzi -
