Isakhiwo esiyisisekelo se-fiber optical ngokuvamile sakhiwe umgodla wangaphandle, ukuvala, umgogodla, nomthombo wokukhanya.I-fiber yemodi eyodwa kanye ne-multi-mode fiber inomehluko olandelayo: Umehluko wombala we-sheath: Ezisetshenziswa ezingokoqobo, umbala we-sheath wangaphandle we-fiber ca...

Eyaziwa nangokuthi amanethiwekhi e-Wide area e-software, i-SD-WAN isibe ngesinye sezihloko ezishisayo phakathi kwama-opharetha enethiwekhi yebhizinisi nabahlinzeki besevisi.Kungani lokhu kwenzeka?Ngakolunye uhlangothi, inani elikhulayo lezinhlelo zokusebenza ezisekelwe ku-inthanethi, izinsiza nohlelo lokusebenza olujulile...

Uma ukunikezwa kukagesi kwe-PoE kwehluleka, kungaphenywa ngezici ezine ezilandelayo.• Hlola ukuthi idivayisi yokugcina eyamukelayo iyakusekela yini ukunikezwa kwamandla kwe-PoE.Njengoba kungewona wonke amadivaysi enethiwekhi angasekela ubuchwepheshe bamandla e-PoE, hlola okokusebenza kobuchwepheshe bamandla e-POE ngaphambi...

I-PPPoE imele iphrothokholi yephoyinti-kuya-iphuzu ku-Ethernet.Iphrothokholi yomhubhe wenethiwekhi ehlanganisa iphrothokholi ye-point-to-point (PPP) kuhlaka lwe-Ethernet.Inika amandla abasingathi be-Ethernet ukuthi baxhume kusixhumi sokufinyelela esikude ngedivayisi yokuhlanganisa ibhuloho.Us...

Ukunikezwa kwamandla kwe-POE kufinyelelwa ngekhebula lenethiwekhi, futhi ikhebula lenethiwekhi lakhiwe ngamapheya amane amapheya asontekile (8 core wire), ngakho izintambo eziyisishiyagalombili eziyinhloko kukhebula yenethiwekhi ziwukushintsha kwe-PoE ukuze kunikeze idatha nemidiya yokudlulisa amandla yamukela idivayisi....

Isinyathelo 1: Thola idivayisi eyamukelayo (PD).Ngokuyinhloko kuwukuthola ukuthi ingabe idivayisi exhunyiwe iyidivayisi eyamukelayo yangempela (i-PD) (eqinisweni, iwukuthola idivayisi eyamukelayo engasekela Amandla phezu kwe-Ethernet standard).I-PoE switch izokhipha i-voltage encane ku ...
