Amandla wePoe Onus: Ukuhanjiswa Kwedatha Kuthuthukisiwe kanye nokulethwa kwamandla

Emkhakheni wezokuxhumana nokuhanjiswa kwedatha, ukuhlanganiswa kwamandla ngaphezulu kobuchwepheshe be-Ethernet (Poe) ubuchwepheshe obushintshile ngokuphelele indlela amadivaysi anikwe amandla futhi axhunyiwe. Okukodwa okunjalo yiyonaPoe on, idivaysi enamandla ehlanganisa amandla wenethiwekhi ye-Passive Optical Network (PON) ngokusebenziseka kalula kokusebenza kwe-poe. Le bhulogi izohlola imisebenzi nezinzuzo zePoe Onu nokuthi ishintsha kanjani isimo sokudluliselwa kwedatha nokunikezwa kwamandla.

I-Poe Onu iyithuluzi elisebenzayo elinemisebenzi eminingi elinikezela nge-1 g / eptive entenative port port ye-uplink kanye ne-8 10 / 100/1000base-T kagesi kagesi ye-Downlink. Lokhu kucushwa kuvumela ukudluliswa kwedatha okungenamthungo kanye nokuxhumana kwamadivayisi ahlukahlukene. Ngaphezu kwalokho, i-Poe Onu isekela ukusebenza kwePoe / Poe +, ukuhlinzeka inketho yamakhamera axhunyiwe amandla, amaphuzu wokufinyelela (ama-APS) namanye ama-terminals namanye ama-terminals namanye ama-terminals. Lo msebenzi ombaxambili wenza i-poe kusu iyingxenye ebalulekile yenethiwekhi yanamuhla kanye nezinhlelo zokubhekwa.

Enye yezinzuzo eziphambili zePoe Onus yikhono labo lokwenza lula futhi zenze lula ukuthunyelwa kwamadivayisi afakiwe. Ngokuhlanganisa ukuhanjiswa kwedatha kanye nemisebenzi yokunikezela kwamandla kudivayisi eyodwa, i-Poe Onus isusa isidingo sempahla ehlukile yamandla kanye nama-cabling amadivayisi axhunyiwe. Lokhu akupheleli nje kuphela isikhathi sokufaka nezindleko, kepha futhi kwandisa ukusebenza kahle kanye nokwethenjwa kwengqalasizinda yenethiwekhi.

I-Poe Onus ilungele ikakhulukazi izinhlelo zokusebenza ezifana nokubhekwa kwe-IP lapho ukuxhumana kwedatha nezidingo zamandla zibalulekile. Ukufakwa nokulungiswa kwenziwa lula ngekhono lamakhamera anamandla neminye imishini yokubheka ngqo kusuka ku-ONU. Lokhu kuzuzisa ikakhulukazi ezindaweni ezingaphandle noma ezikude lapho ukufinyelela kwamandla kungakhawulelwa.

Amadivayisi anikwe amandla e-PoE angahlanganiswa kalula futhi anikiswe amandla ngaphandle kwesidingo sama-adaptha angeziwe wamandla noma ingqalasizinda. Lokhu kwenza lula ukunwetshwa kwenethiwekhi kanye nokuphathwa, okuvumela ukuhlanganiswa okungenamthungo kwamadivayisi amasha njengoba inethiwekhi ikhula.

Kafushane,Poe onImele ukuhlanganiswa okunamandla kokudluliselwa kwedatha namandla okuhambisa amandla. Amandla alo okuhlinzeka ngokuxhumana okusheshayo nokulethwa kwamandla kudivayisi eyodwa, ecwecwecwecwenzi kwenza kube yimpahla ebalulekile yokuxhumana kwezimanje nezinhlelo zokusebenza zokubhekwa. Njengoba isidingo sengqalasizinda yenethiwekhi esebenza kahle nethembekile iyaqhubeka nokukhula, i-poe onus iba yisixazululo esiguquguqukayo nesibalulekile sokuhanjiswa kwedatha okuthuthukisiwe kanye nokunikezwa kwamandla.
