Hauv kev sib txuas lus thiab kev xa cov ntaub ntawv, kev koom ua ke ntawm Power over Ethernet (PoE) thev naus laus zis tau hloov pauv tag nrho txoj kev siv hluav taws xob thiab kev sib txuas ntawm cov khoom siv. Ib qho kev tsim kho tshiab no yogPOE ONU, ib lub cuab yeej muaj zog uas sib txuas lub zog ntawm lub network optical passive (PON) nrog rau qhov yooj yim ntawm PoE functionality. Cov blog no yuav tshawb nrhiav cov haujlwm thiab cov txiaj ntsig ntawm POE ONU thiab nws hloov pauv qhov toj roob hauv pes ntawm kev xa cov ntaub ntawv thiab kev muab hluav taws xob li cas.
Lub POE ONU yog ib lub cuab yeej ua haujlwm ntau yam uas muab 1 G/EPON adaptive PON port rau uplink thiab 8 10/100/1000BASE-T electrical ports rau downlink. Qhov kev teeb tsa no tso cai rau kev xa cov ntaub ntawv tsis muaj kev sib txuas thiab kev sib txuas ntawm ntau yam khoom siv. Tsis tas li ntawd, POE ONU txhawb nqa PoE/PoE+ functionality, muab kev xaiv los txuas lub koob yees duab, cov chaw nkag (APs) thiab lwm yam terminals. Qhov dual functionality ua rau POE ONU yog ib qho tseem ceeb ntawm cov network niaj hnub thiab kev saib xyuas systems.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm POE ONUs yog lawv lub peev xwm los ua kom yooj yim thiab yooj yim rau kev xa cov khoom siv network. Los ntawm kev koom ua ke cov ntaub ntawv xa mus thiab cov haujlwm muab hluav taws xob rau hauv ib lub cuab yeej, POE ONUs tshem tawm qhov xav tau cov khoom siv hluav taws xob sib cais thiab cabling rau cov khoom siv txuas nrog. Qhov no tsis tsuas yog txo lub sijhawm teeb tsa thiab cov nqi, tab sis kuj ua rau kom muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv network.
Cov POE ONUs yog qhov tsim nyog rau cov ntawv thov xws li IP saib xyuas qhov twg kev sib txuas lus ntawm cov ntaub ntawv thiab lub zog xav tau yog qhov tseem ceeb. Kev teeb tsa thiab kev saib xyuas tau yooj yim dua nrog lub peev xwm los muab lub zog rau cov koob yees duab thiab lwm yam khoom siv saib xyuas ncaj qha los ntawm ONU. Qhov no yog qhov tshwj xeeb tshaj yog rau sab nraum zoov lossis thaj chaw deb uas kev nkag mus rau lub zog yuav raug txwv.
Ntxiv mus, POE ONU txoj kev txhawb nqa rau PoE / PoE + cov haujlwm ntxiv qhov yooj yim thiab scalability rau lub network. PoE-enabled cov khoom siv tuaj yeem yooj yim koom ua ke thiab powered yam tsis tas yuav tsum tau ntxiv cov adapters fais fab lossis infrastructure. Qhov no ua kom yooj yim rau kev nthuav dav thiab kev tswj hwm network, tso cai rau kev sib koom ua ke ntawm cov khoom siv tshiab thaum lub network loj hlob.
Hauv luv luv,POE ONUsawv cev rau kev sib koom ua ke ntawm kev xa cov ntaub ntawv thiab lub zog muab hluav taws xob. Nws lub peev xwm los muab kev sib txuas ceev ceev thiab kev xa hluav taws xob hauv ib lub cuab yeej me me ua rau nws yog ib qho khoom muaj nqis rau kev sib txuas lus niaj hnub thiab kev saib xyuas. Raws li qhov kev thov rau cov khoom siv network zoo thiab txhim khu kev qha txuas ntxiv mus, POE ONUs dhau los ua qhov kev daws teeb meem ntau yam thiab tseem ceeb rau kev xa cov ntaub ntawv zoo dua thiab kev muab hluav taws xob.
