Ingabe imodi eyodwa kanye nemodi eminingi yokushintsha kwezimboni ingashintshana?
Lapho uthenga iswishi yezimboni, amakhasimende azobuzwa ukuthi afuna i-fiber eyodwa yemodi eyodwa, i-dual-fiber yemodi eyodwa, i-multi-mode dual-fiber, njll., nokuthi isetshenziswa kuphi.Lokhu kuzoqondwa kuphela uma sebenokuqonda okucacile kokuthengwa kwamaswishi ezimboni.Yini t...Funda kabanzi -
Ungayisebenzisa kanjani i-PoE Injector?
Ngabe injector ye-PoE isebenza kanjani?Lapho amaswishi noma amanye amadivaysi angenawo umsebenzi wokuphakelwa kwamandla exhunywe kumadivayisi anamandla (njengamakhamera e-IP, ama-APs angenawaya, njll.), ukunikezwa kwamandla kwe-PoE kunganikeza amandla nokusekelwa kokudlulisa idatha kulawa madivayisi anikwe amandla ngesikhathi esifanayo, nge-transmiss. ...Funda kabanzi -
Yini i-PoE injector?
I-PoE (Amandla phezu kwe-Ethernet) ibhekisela emandleni phezu kobuchwepheshe be-Ethernet adlulisela amandla kanye nedatha ngesikhathi esisodwa ngekhebula epheya esontekile.Ukusetshenziswa kwalobu buchwepheshe kungathuthukisa ngempumelelo ukuzinza nokuguquguquka kwenethiwekhi, ngakho-ke kuthandwa kakhulu ngabantu.Okwamanje, t...Funda kabanzi -
Hlukanisa uhlobo lwembobo yokushintsha ye-Ethernet ngokwezinga lokudlulisela
Izinga lokudlulisela liyisici esibalulekile ekunqumeni uhlobo lwembobo yokushintsha ye-Ethernet.Njengamanje, izinga lokudlulisela lokushintshwa kwe-Ethernet yi-1G/10G/25G/40G/100G noma ngaphezulu.Okulandelayo yizinhlobo zezimbobo ezivamile zalezi zinguquko ze-Ethernet ezinamazinga okudlulisela ahlukene.RJ45 kwe...Funda kabanzi -
Ungakuxazulula kanjani ukubambezeleka kwenethiwekhi okubangelwa iswishi ye-Ethernet.
Ungakukala kanjani ukubambezeleka kwenethiwekhi ekushintsheni kwe-Ethernet?Njengoba kungabonwa esahlukweni esandulele, ukushintsha ukubambezeleka kungenye yezinto ezibalulekile eziholela ekubambezelekeni kwenethiwekhi.Ngakho-ke siyikala kanjani i-switch latency?Ukulibaziseka kokushintsha kukalwa ukusuka kutheku kuye kwelinye kuswishi ye-Ethernet, futhi kungabikwa ngokuphindaphinda...Funda kabanzi -
Kuyini ukubambezeleka kwenethiwekhi ekushintsheni kwe-Ethernet?
Ukubambezeleka kwenethiwekhi kubhekisela esikhathini sokulinda senethiwekhi, esibhekisela esikhathini sokuya nokubuya ukuze iphakethe ledatha lithunyelwe lisuka kukhompyutha yomsebenzisi liye kuseva yewebhusayithi, bese ngokushesha lisuka kuseva yewebhusayithi liye kukhompyutha yomsebenzisi.Ukubambezeleka kwenethiwekhi kungenye yezinto ezithinta ingqikithi...Funda kabanzi -
Qhathanisa amaswishi e-PoE+ ne-PoE++
Amandla phezu kwe-Ethernet (i-PoE) ubuchwepheshe bokuhlinzeka ngogesi obusekelwe kunethiwekhi yendawo (LAN), engadlulisela amandla nedatha kudivayisi ngentambo yenethiwekhi eku-Ethernet.Ukusetshenziswa kwalobu buchwepheshe kunganciphisa kakhulu izindleko zokusebenza futhi konge isikhathi sokusebenza.Okwamanje, kukhona...Funda kabanzi -
Shintsha idizayini yokunikezela amandla engasasebenzi
Njengamanje, amaswishi amaningi emakethe, ikakhulukazi amaswishi amadala, asebenzisa ugesi owodwa kuphela.Uma ukunikezwa kwamandla kwehluleka (njengokuhluleka kwamandla), iswishi ayikwazi ukusebenza ngokujwayelekile, noma ngisho ikhubaze inethiwekhi.Amandla angadingekile ayisixazululo esikahle sale nkinga.Amaswishi aklanywe nge-wi...Funda kabanzi -
Kungani amamojula we-SFP optical edumile?
Kungani amamojula we-SFP optical edumile?Umthamo we-SFP optical module wehliswa ngesigamu uma kuqhathaniswa nevolumu ye-GBIC optical module.Inombolo yezimbobo ze-SFP kuphaneli efanayo izoba kabili kunaleyo ye-GBIC optical module.Imojuli efanayo ye-SFP ye-optical ine-plug-and-play mini optical f...Funda kabanzi -
Wazini ngemojuli ye-SFP?
Iyini imojuli ye-SFP?Imojula ye-SFP iyisisetshenziswa esibonakalayo esiguqula amasiginali kagesi wegigabit abe amasignali optical.Kuyimojula ye-gigabit optical transceiver esezingeni elijwayelekile embonini engaxhunywa ku-SFP yezinto zokusebenza zenethiwekhi ezinjengamaswishi, amarutha, ne-media con...Funda kabanzi -
Ibanga lokudlulisela eliphephile kanye nokukhethwa kwekhebula lenethiwekhi lokuphakelwa kwamandla kwe-POE
Ibanga eliphephile lokudlulisa amandla e-POE lingamamitha angu-100, futhi kuyanconywa ukusebenzisa intambo yenethiwekhi yethusi ye-Cat 5e.Kungenzeka ukudlulisa amandla e-DC ngentambo evamile ye-Ethernet ibanga elide, kungani-ke ibanga lokudlulisela lilinganiselwe kumamitha ayi-100?Okulandelayo, sizolandela i-JHA T...Funda kabanzi -
Ungakhetha kanjani i-fiber video converter ohlelweni lokuqapha ukuphepha?
Ama-transceivers optical wevidiyo yedijithali yamashaneli amaningi angaba nemisebenzi eminingi, futhi uhlobo ngalunye lomsebenzi lunezidingo zenkomba yezobuchwepheshe ehambisanayo, njengenkomba yevidiyo, inkomba yomsindo, inkomba yedatha ye-asynchronous, inkomba ye-Ethernet, inkomba yocingo nokunye.Izinkomba zobuchwepheshe ezithile zingadinga ...Funda kabanzi
