Ukukhethwa kwemithombo yeendaba yokuhanjiswa kwedatha ihlala iyisihloko esiphikisanayo, ngakumbi kwiindawo ezinikezelweyo (njengamaziko edatha). Imiba yobugcisa kunye neshishini kufuneka ithathelwe ingqalelo. Abanye abantu bacinga ukuba kufuneka kukhethwe iingcingo zobhedu, ngelixa abanye becinga ukuba...

Xa kuthengwa i-industrial switch, abathengi baya kubuzwa ukuba ngaba bafuna i-fiber eyodwa-mode enye, i-mode-mode-dual-fiber, i-multi-mode dual-fiber, njl., kunye nalapho zisetyenziswa khona. Ezi ziya kuqondwa kuphela xa benokuqonda okucacileyo kwepu...

Sisebenza njani isitofu se-PoE? Xa ukutshintshwa okanye ezinye izixhobo ezingenamsebenzi wokunikezelwa kwamandla zixhunywe kwizixhobo ezinamandla (ezifana neekhamera ze-IP, i-wireless APs, njl.), Umbane we-PoE unokubonelela ngenkxaso yombane kunye nokuhanjiswa kwedatha kwezi zixhobo ezinamandla ...

I-PoE (Amandla phezu kwe-Ethernet) ibhekisela kumandla phezu kweteknoloji ye-Ethernet ehambisa amandla kunye nedatha ngaxeshanye ngentambo ephothiweyo. Ukusetyenziswa kobu buchwepheshe kunokuphucula ngokufanelekileyo uzinzo kunye nokuguquguquka kwenethiwekhi, ngoko ke ku ...

Umyinge wothumelo ngumba obalulekileyo ekumiseleni uhlobo lwe-Ethernet switch port. Okwangoku, izinga lokudluliselwa kwe-Ethernet switches yi-1G/10G/25G/40G/100G okanye nangaphezulu. Oku kulandelayo ziindidi zezibuko ezingundoqo zezi zitshixo ze-Ethernet ezinedif...

Ukulinganisa njani ukulibaziseka kwenethiwekhi kwi-Ethernet switch? Njengoko kunokubonwa kwisahluko esidlulileyo, ukulibaziseka kokutshintsha yenye yezinto eziphambili ezikhokelela ekulibazisekeni kwenethiwekhi. Ke silinganisa njani iswitshi latency? Ukulibaziseka kokutshintsha kubalwa ukusuka kwizibuko ukuya kwizibuko kwi-Ethernet...

I-Network latency ibhekisa kwixesha lokulinda lothungelwano, elibhekiselele kwixesha lokuya nokubuya ukuze ipakethi yedatha ithunyelwe ukusuka kwikhompyuter yomsebenzisi ukuya kwiseva yewebhusayithi, kwaye kwangoko ukusuka kwiseva yewebhusayithi ukuya kwikhompyuter yomsebenzisi. Ulibaziseko lwenethiwekhi yenye ye...

Amandla phezu kwe-Ethernet (i-PoE) iteknoloji yokubonelela ngombane esekelwe kwinethiwekhi yendawo yendawo (LAN), enokudlulisa amandla kunye nedatha kwisixhobo ngentambo yenethiwekhi kwi-Ethernet. Ukusetyenziswa kobu buchwepheshe kunokunciphisa kakhulu iindleko zokusebenza kunye nokugcina ...

Okwangoku, uninzi lokutshintsha kwimarike, ngakumbi izitshixo ezindala, zisebenzisa umbane omnye kuphela. Ukuba unikezelo lwamandla luyasilela (njengokusilela kombane), iswitshi ayinakusebenza ngokuqhelekileyo, okanye ide ikhubaze uthungelwano.Ubonelelo lwamandla oluNgafunekiyo sisisombululo esifanelekileyo ...

Kutheni iimodyuli ezibonakalayo ze-SFP zithandwa? Umthamo wemodyuli ye-SFP optical iyancipha ngesiqingatha xa kuthelekiswa nomthamo we-GBIC optical module. Inani leezibuko ze-SFP kwiqela elinye liya kuba kabini kwimodyuli ye-GBIC optical. Kwale modu yokukhanya ye-SFP...
