Hauv kev sib koom tes thiab cov ntaub ntawv sib kis, kev sib koom ua ke ntawm lub zog (PoE) thev naus laus zis tau hloov tag nrho cov khoom siv tau siv thiab txuas nrog. Ib qho kev tsim kho tshiab yog tusPohe onu, lub cuab yeej muaj zog uas sib xyaw ua ke lub zog ntawm lub qhov passive kho qhov muag network (pon) nrog kev yooj yim ntawm cov kev ua haujlwm poe. Cov blog no yuav tshawb txog cov haujlwm thiab cov txiaj ntsig ntawm PoE onu thiab li cas hloov cov toj roob hauv pes ntawm cov ntaub ntawv ntawm cov ntaub ntawv kis thiab fais fab.
Poe Onu yog ntau lub cuab yeej siv ntau uas muab 1 g / epon Haum Pon chaw nres nkoj rau Uplink thiab 8 10/1000base-t hluav taws xob ports rau downlink. Qhov kev teeb tsa no tso cai rau kev hloov cov ntaub ntawv hloov chaw thiab kev sib txuas ntawm ntau yam khoom siv. Tsis tas li ntawd, PoE ONU txhawb POE / POE + kev ua haujlwm, muab kev xaiv rau cov koob yees duab sib txuas, cov ntsiab lus nkag mus (APS) thiab lwm cov kev txiav txim siab. Qhov no ob txoj haujlwm ua rau poe onu ib qho tseem ceeb ntawm cov nruab nrab network thiab kev soj ntsuam cov tshuab.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm Poe Onting yog lawv lub peev xwm los ua kom yooj yim thiab yooj yim rau kev xa tawm ntawm cov khoom siv networked. Los ntawm kev sib xyaw cov ntaub ntawv sib kis thiab cov fais fab kev sib zog ua ke rau hauv ib lub cuab yeej, PoE onus tshem tawm qhov kev xav tau ntawm cov khoom siv hluav taws xob sib txuas. Qhov no tsis yog txo qis lub sijhawm ua haujlwm thiab cov nqi, tab sis kuj tseem nce cov txiaj ntsig zoo tag nrho thiab kev ntseeg tau ntawm cov network infrastrastructure.
Poe onus yog qhov tshwj xeeb rau cov ntawv thov xws li IP kev soj ntsuam qhov twg cov ntaub ntawv txuas thiab lub zog yuav tsum tseem ceeb. Kev teeb tsa thiab kev txij nkawm tau yooj yim dua nrog lub peev xwm rau cov khoom siv hluav taws xob ncaj ncees thiab lwm yam kev soj ntsuam sab nrauv ncaj qha los ntawm ONU. Qhov no yog qhov tseem ceeb tshwj xeeb rau sab nraum zoov lossis chaw taws teeb qhov chaw uas muaj peev xwm nkag tau tsawg.
Tsis tas li ntawd, POE ONU txoj kev txhawb nqa rau Poe / Poe + Functions ntxiv cov kev hloov pauv ntxiv thiab thev naus laus zis mus rau lub network. POE-enre-enabled cov cuab yeej tuaj yeem yooj yim sib xyaw thiab siv tau yam uas tsis muaj kev xav tau rau lub zog ntxiv lossis cov khoom siv hluav taws xob ntxiv. Qhov yooj yim ua kom yooj yim network nthuav dav thiab kev tswj hwm, tso cai rau kev sib xyaw ua ke ntawm cov khoom siv tshiab ua lub network loj tuaj.
Hauv ntej,Pohe onusawv cev rau ib qho muaj zog sib koom tes ntawm cov ntaub ntawv kis thiab fais fab muaj peev xwm ua tau. Nws lub peev xwm los muab kev sib txuas nrawm nrawm thiab cov khoom xa hluav taws xob hauv ib qho, cov cuab yeej ua kom sib xyaw ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov niaj hnub no. Raws li qhov kev thov kom muaj txiaj ntsig thiab txhim khu kev qha network txuas ntxiv mus ua cov ntaub ntawv kis thiab fais fab tuag.
