Buyini ubuchwepheshe be-POE?

I-PoE (Power Over Ethernet) ibhekisela kubuchwepheshe obunikeza amandla e-DC kwamanye amatheminali asekelwe ku-IP (isb. izingcingo ze-IP, izindawo zokungena ezingenantambo ze-LAN, amakhamera enethiwekhi, njll.) kuyilapho idlulisela amasignali edatha kulawo madivayisi ngaphandle kwanoma iyiphi enye indlela.

izinguquko kwingqalasizinda yekhebula ehleliwe ekhona.

Izingxenye zesistimu ye-PoE.

Isistimu yonke iqukethe i-PSE (Isisetshenziswa Sokuhlinzeka Amandla) kanye ne-PD (Idivayisi Yamandla).I-PSE iyidivayisi enikeza amandla kumadivayisi eklayenti le-Ethernet futhi ingumphathi wayo yonke inqubo ye-POE Amandla phezu kwe-Ethernet.Ukudluliswa

medium siquketheamakhanda ekristalu, amamojula (i-POE), amaphaneli okuchibiyela nezintambo zenethiwekhi.

b

Izimo zohlelo lomkhiqizo.

Isetshenziswa ezinhlelweni zemishini ehlukahlukene ezinikezwa ubuchwepheshe be-POE.Njengoba izinto zikagesi ezisebenza nge-Ethernet zingasetshenziswa ngaphandle kwezindawo zikagesi ezengeziwe, isikhathi nemali echithwa ukulungisa izintambo zikagesi kungonga futhi

izindleko zalo lonke uhlelo zingancishiswa.

Izicelo ze-POE wireless APs

Ukusetshenziswa kokuqapha okukude kwe-POE

Ukusetshenziswa kwamatheminali ahlakaniphile e-POE

Njengamanje, izingxenye eziningi zamandla asekhaya kanye nezintambo zokuxhumana zaseShayina ziqukethe i-halogen, kuzo zonke izingozi zomlilo eziningana ezinkulu zasekhaya eminyakeni yamuva nje, izisulu azikwazi ukubalekela i-90% ngoba ukushiswa kwekhebula kukhipha igesi enobuthi enobuthi, futhi ukushiswa kukhishwe ukushisa okuningi, intuthu, bangela izisulu izinkinga zokuphefumula, kuholele enhlekeleleni!Kwezinye izindawo ezinokuminyana okukhulu kwezimoto, njengeziteshi zesitimela, izikhumulo zezindiza, izikhungo zezingqungquthela nemibukiso, izibhedlela, izakhiwo zamahhovisi ezisezingeni eliphezulu, njll., i-Datang Cable ikuncoma izintambo ze-LSZH.Imikhiqizo yekhebula ye-Datang Telecom ephansi yentuthu ye-halogen yekhwalithi ephezulu kakhulu, izinto ezinhle kakhulu, ukuvikelwa kwemvelo okuluhlaza, ayikwazi nje kuphela ukuhlangabezana nezindinganiso zebanga lomlilo lezwe nelezimboni ezihlakaniphile, okubaluleke kakhulu, ukuphelezela ukuphepha kwakho.
