Isebenza kanjani i-router?
Irutha iyidivayisi yenethiwekhi yongqimba 3.Ihabhu lisebenza kungqimba lokuqala (isendlalelo esibonakalayo) futhi alinawo amandla okucubungula ahlakaniphile.Uma i-current yembobo eyodwa idluliselwa kuhabhu, ivele idlulisele okwamanje kwezinye izimbobo, futhi ayinandaba noma amakhompyutha axhumeke kwezinye...Funda kabanzi -
Ahlukaniswa kanjani ama-transceiver optical ngokuya ngezinhlobo zobuchwepheshe kanye nezinhlobo ze-interface?
Ama-transceivers optical angahlukaniswa ngezigaba ze-3 ngokusho kobuchwepheshe: i-PDH, i-SPDH, i-SDH, i-HD-CVI.I-PDH optical transceiver: I-PDH (i-Plesiochronous Digital Hierarchy, i-quasi-synchronous digital series) i-optical transceiver iyi-transceiver ebonakalayo enamandla amancane, evame ukusetshenziswa ngababili,...Funda kabanzi -
Isho ukuthini i-optical transceiver 2M, futhi buyini ubudlelwano phakathi kwe-optical transceiver E1 kanye ne-2M?
I-Optical transceiver iyisisetshenziswa esiguqula amasiginali amaningi we-E1 abe amasignali abonakalayo.I-Optical Transceiver ibizwa nangokuthi imishini yokudlulisa amehlo.Ama-Optical transceivers anamanani ahlukene ngokwenombolo ye-E1 (okungukuthi, i-2M) yamachweba adlulisiwe.Ngokuvamile, i-optical transn encane kakhulu...Funda kabanzi -
Ukuhlaziywa kwezinhlobo ze-fiber switch
Ukushintsha Kwesendlalelo Sokufinyelela Ngokuvamile, ingxenye yenethiwekhi exhunywe ngokuqondile kubasebenzisi noma efinyelela kunethiwekhi ibizwa ngokuthi isendlalelo sokufinyelela, futhi ingxenye ephakathi kwesendlalelo sokufinyelela nesendlalelo esiyinhloko ibizwa ngokuthi isendlalelo sokusabalalisa noma isendlalelo sokuhlangana.Amaswishi okufinyelela ngokuvamile asetshenziselwa uku...Funda kabanzi -
Iyini ikhebula le-Cat5e/Cat6/Cat7?
Uyini umehluko phakathi kwe-Ca5e, i-Cat6, ne-Cat7?Isigaba Sesihlanu (CAT5): Imvamisa yokudlulisa ingu-100MHz, esetshenziselwa ukudlulisa kwezwi nokudluliswa kwedatha ngezinga eliphezulu lokudlulisela elingu-100Mbps, elisetshenziswa kakhulu kumanethiwekhi angu-100BASE-T kanye ne-10BASE-T.Lena i-Ethernet esetshenziswa kakhulu ...Funda kabanzi -
Iyini imojuli ye-optical engu-1*9?
Umkhiqizo we-1*9 ohlanganisiwe we-optical module wakhiqizwa okokuqala ngo-1999. Ungumkhiqizo wemojula ye-fixed optical.Ivame ukuphulukiswa ngokuqondile (i-soldered) ebhodini lesifunda lemishini yokuxhumana futhi isetshenziswe njengemojula ye-optical engaguquki.Kwesinye isikhathi ibizwa nangokuthi i-9-pin noma i-9PIN optical module..A...Funda kabanzi -
Uyini umehluko phakathi kokushintsha kweLayer 2 kanye neLayer 3?
1. Amaleveli okusebenza ahlukene: Amaswishi esendlalelo sesi-2 asebenza kusendlalelo sesixhumanisi sedatha, futhi amaswishi Esendlalelo sesi-3 asebenza kungqimba yenethiwekhi.Ukushintsha kwesendlalelo sesi-3 akuphumeleli nje kuphela ukudlulisela phambili amaphakethe edatha ngesivinini esiphezulu, kodwa futhi kuzuzisa ukusebenza kahle kwenethiwekhi ngokwemibandela yenethiwekhi eyahlukene.2. Iphrinta...Funda kabanzi -
Ungayisebenzisa kanjani i-fiber optic transceivers?
Umsebenzi we-fiber optic transceivers ukuguqula phakathi kwamasignali optical kanye namasignali kagesi.Isignali yokubona okokufaka okuvela ku-optical port, futhi isignali kagesi iphuma embobeni kagesi, futhi ngokuphambene nalokho.Inqubo icishe ihambe kanje: guqula isignali kagesi ...Funda kabanzi -
Ukushintshwa Kwendandatho Ephethwe Kusebenza Kanjani?
Ngokuthuthuka kwemboni yezokuxhumana kanye nokwaziswa komnotho wezwe, imakethe yokushintshashintsha kwenethiwekhi yendandatho ephethwe ikhule kancane kancane.Ibiza kakhulu, iguquguquka kakhulu, ilula futhi kulula ukuyisebenzisa.Ubuchwepheshe be-Ethernet sebeyinethiwekhi ebalulekile ye-LAN...Funda kabanzi -
Ukuthuthukiswa kwe-transceiver optical yocingo
Ama-transceivers ocingo ezwe lethu athuthuke ngokushesha ngokuthuthukiswa kwemboni yokuqapha.Ukusuka ku-analog kuye kudijithali, bese kusuka kudijithali kuya ekuchazeni okuphezulu, ziqhubeka zithuthuka.Ngemuva kweminyaka yokuqongelelwa kobuchwepheshe, sebethuthuke baba ngabavuthwe kakhulu...Funda kabanzi -
Yini i-IEEE 802.3&Subnet Mask?
Iyini i-IEEE 802.3?I-IEEE 802.3 iyiqembu elisebenzayo elabhala isethi evamile ye-Institute of Electrical and Electronics Engineers (IEEE), echaza isilawuli sokufinyelela okumaphakathi (MAC) kuzo zombili izendlalelo zesixhumanisi esibonakalayo nedatha ye-Ethernet enezintambo.Lokhu ngokuvamile ubuchwepheshe benethiwekhi yendawo (LAN) obu...Funda kabanzi -
Uyini umehluko phakathi kwe-switch kanye ne-fiber converter?
I-Optical fiber transceiver iyithuluzi elibiza kakhulu futhi elivumelana nezimo.Ukusetshenziswa okuvamile ukuguqula amasignali kagesi ngamapheya asontekile abe amasignali okubona.Ngokuvamile isetshenziswa kuzintambo zethusi ze-Ethernet ezingakwazi ukumbozwa futhi kufanele zisebenzise imicu yokubona ukuze kunwetshwe ibanga lokudlulisela.E...Funda kabanzi
