1. Ukushintsha kwezimboni kubizwa nangokuthi ama-switch Ethernet yezimboni. Ngaphansi kwesimo samanje, ngokuthuthuka okuqhubekayo nokushesha kanye nokuthuthuka kobuchwepheshe benethiwekhi, isidingo samanethiwekhi emkhakheni wezimboni, ikakhulukazi emkhakheni we-indus...

I-Optical transceiver iyisisetshenziswa esiguqula amasiginali amaningi we-E1 abe amasignali abonakalayo. I-Optical Transceiver ibizwa nangokuthi imishini yokudlulisa amehlo. Ama-transceivers okubona anezintengo ezihlukene ngokwenani lama-E1 (okungukuthi, 2M) adluliselwe....

Ama-transceivers optical angahlukaniswa abe yizigaba ze-3 ngokusho kobuchwepheshe: i-PDH, i-SPDH, i-SDH, i-HD-CVI. I-PDH optical transceiver: PDH (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) i-optical transceiver iyi-transceiver ebonakalayo enamandla amancane...

Irutha iyidivayisi yenethiwekhi yesendlalelo 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 ukuthi...

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. Acc...

Ukushintsha Umthamo Umthamo wokushintsha weswishi, owaziwa nangokuthi umkhawulokudonsa ongemuva noma umkhawulokudonsa oshintshayo, inani eliphakeme ledatha elingasingathwa phakathi kwephrosesa yesixhumi esibonakalayo noma ikhadi lesixhumi esibonakalayo kanye nebhasi ledatha. Ikepisi yokushintshisana...

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. Lokhu...

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 njenge-module optical ehleliwe. Kwesinye isikhathi kuphinde kubizwe...

1. Amaleveli okusebenza ahlukene: Amaswishi esendlalelo sesi-2 asebenza kusendlalelo sesixhumanisi sedatha, futhi amaswishi Esendlalelo sesi-3 asebenza kungqimba yenethiwekhi. Ukushintsha kwe-Layer 3 akuphumeleli nje kuphela ukudlulisela phambili amaphakethe edatha ngesivinini esiphezulu, kodwa futhi kuzuzisa ukusebenza kahle kwenethiwekhi ngokuya ngokuhlukahluka...

Ama-transceivers okusebenza ngocingo ezwe lethu athuthuke ngokushesha ngokuthuthukiswa kwemboni yokuqapha. Ukusuka ku-analog kuye kudijithali, bese kusuka kudijithali kuya ekuchazeni okuphezulu, aqhubeka ethuthuka. Ngemuva kweminyaka yokuqongelela ubuchwepheshe, ba...
