Iyini i-switch ephethwe&SNMP?
Iyini iswishi ephethwe?Umsebenzi wokushintsha okuphethwe ukugcina zonke izinsiza zenethiwekhi zisesimweni esihle.Imikhiqizo yokushintsha yokuphatha inethiwekhi ihlinzeka ngezindlela ezahlukene zokuphatha inethiwekhi ezisuselwe kutheminali yokulawula i-terminal (Console), ngokusekelwe ekhasini leWebhu futhi isekela i-Telnet ukuze ungene ku-n...Funda kabanzi -
Iyini i-Optical fiber transceiver?
I-Optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amade kanye namasiginali okubona amabanga amade.Ibizwa nangokuthi i-fiber converter ezindaweni eziningi.Umkhiqizo ngokuvamile usetshenziswa endaweni yangempela yenethiwekhi lapho...Funda kabanzi -
Iyini indandatho yesiphepho ne-Ethernet?
Siyini isiphepho sokusakaza?Isiphepho sokusakaza sisho nje ukuthi lapho idatha yokusakaza ikhukhula inethiwekhi futhi ayikwazi ukucutshungulwa, ithatha inani elikhulu lomkhawulokudonsa wenethiwekhi, okuholela ekungakwazini kwezinsizakalo ezijwayelekile ukusebenza, noma ngisho nokukhubazeka okuphelele, kanye "nesiphepho sokusakaza". .Funda kabanzi -
Izici eziyinhloko zobuchwepheshe be-GPON
(1) Umkhawulokudonsa ophezulu ongakaze ubonwe.Izinga le-GPON liphezulu njenge-2.5 Gbps, elingahlinzeka ngomkhawulokudonsa omkhulu owanele ukuhlangabezana nesidingo esikhulayo somkhawulokudonsa ophezulu kumanethiwekhi azayo, futhi izici zayo ze-asymmetric zingazivumelanisa kangcono nemakethe yesevisi yedatha ye-broadband.(2) Ukufinyelela ngesevisi ephelele...Funda kabanzi -
Yini i-GPON&EPON?
Yini i-Gpon?Ubuchwepheshe be-GPON (Gigabit-Capable PON) yisizukulwane sakamuva sobuchwepheshe bokufinyelela obuhlanganisiwe be-broadband passive optical obusekelwe kuzinga le-ITU-TG.984.x.Inezinzuzo eziningi ezifana nomkhawulokudonsa ophezulu, ukusebenza kahle okuphezulu, ukumbozwa okukhulu, nokuxhumana okucebile komsebenzisi.Iningi labasebenzisi libongela...Funda kabanzi -
Kuyini ukushintshwa kwe-PoE?Umehluko phakathi kwe-PoE switch ne-PoE+ switch!
I-PoE switch iyidivayisi esetshenziswa kabanzi embonini yezokuphepha namuhla, ngoba iwushintsho olunikeza amandla nokudluliswa kwedatha kumaswishi akude (njengamafoni we-IP noma amakhamera), futhi idlala indima ebaluleke kakhulu.Uma usebenzisa amaswishi e-PoE, amanye amaswishi e-PoE amakwe nge-PoE, kanti amanye a...Funda kabanzi -
