Ukukhethwa kwemidiya yokudlulisela isikhungo sedatha kuhlale kuyisihloko esiyimpikiswano, ikakhulukazi ezindaweni ezizinikele (njengezikhungo zedatha). Izinkinga zobuchwepheshe nezebhizinisi zidinga ukucatshangelwa. Abanye abantu bacabanga ukuthi izintambo zethusi kufanele zikhethwe, kuyilapho abanye bethi...

Lapho uthenga iswishi yemboni, amakhasimende azobuzwa ukuthi afuna i-fiber eyodwa yemodi eyodwa, i-dual-fiber yemodi eyodwa, i-multi-mode dual-fiber, njll., nokuthi isetshenziswa kuphi. Lezi zizoqondwa kuphela lapho sebenokuqonda okucacile kwe-pu...

Ngabe injector ye-PoE isebenza kanjani? Uma amaswishi noma amanye amadivaysi angenawo umsebenzi wokuphakelwa kwamandla exhunywe kumadivayisi anamandla (njengamakhamera we-IP, ama-APs angenawaya, njll.), ukunikezwa kwamandla kwe-PoE kunganikeza amandla nokusekelwa kokudlulisa idatha kulawa madivaysi anamandla...

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 ...

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 ezijwayelekile zalezi zinguquko ze-Ethernet ezine-dif...

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 echwebeni kuye kwelinye ngentambo ye-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 ye...

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 ...

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.Izinsiza zamandla ezingadingekile ziyisixazululo esikahle ...

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. I-modu efanayo ye-SFP...
