Ulwakhiwo olusisiseko lwefiber optical ngokubanzi luqulunqwe sisilaphu sangaphandle, isigqubuthelo, undoqo kunye nomthombo wokukhanya.Ifiber yemowudi enye kunye nefiber yemowudi eninzi inomahluko ulandelayo: Umahluko wombala weSheath: Kwizicelo ezisebenzayo, umbala wesheath wangaphandle wefiber ca...

Ikwaziwa njengesoftware-echaziweyo Uthungelwano lwendawo ebanzi, i-SD-WAN ibe yenye yezona zihloko zishushu phakathi kwabaqhubi benethiwekhi yeshishini kunye nababoneleli benkonzo.Kutheni le nto isenzeka?Kwelinye icala, inani elandayo lezicelo ezisekwe kwi-Intanethi, iinkonzo kunye ne-app ebanzi...

Xa unikezelo lwamandla lwe-PoE lusilela, lunokuphandwa kwezi nkalo zine zilandelayo.• Jonga ukuba isixhobo sokuphela kokufumana siyakuxhasa unikezelo lombane lwe-PoE.Kuba ingezizo zonke izixhobo zenethiwekhi ezinokuxhasa itekhnoloji yamandla e-PoE, jonga izixhobo zetekhnoloji yamandla e-POE ngaphambi...

I-PPPoE imele i-point-to-point protocol kwi-Ethernet.I-protocol ye-tunnel yenethiwekhi edibanisa i-point-to-point protocol (PPP) kwisakhelo se-Ethernet.Ivumela iinginginya ze-Ethernet ukuba ziqhagamshele kwindawo yokufikelela kwindawo ekude ngesixhobo esilula sokudibanisa.

Unikezelo lwamandla lwe-POE luphunyezwa ngentambo yothungelwano, kwaye intambo yothungelwano iqulunqwe ngamaqela amane ezibini ezijijekileyo (iingcingo eziyi-8 ezingundoqo), ngoko ke iingcingo ezisibhozo ezingundoqo kwintambo yomnatha zilutshintsho lwePoE ukubonelela ngedatha kunye nemidiya yokuhambisa amandla ifumana isixhobo....

Inyathelo 1: Khangela isixhobo esifumanayo (PD).Ikakhulu ukufumanisa ukuba isixhobo esiqhagamshelweyo sisixhobo sokufumana ngokwenene (PD) (enyanisweni, kukufumanisa isixhobo esifumanayo esinokuxhasa i-Power over Ethernet standard).Ukutshintsha kwePoE kuya kukhupha amandla ombane amancinci kwi ...
