Kule mihla, kwiidolophu zentlalo, iikhamera zokucupha zifakwe kwikona nganye.Siza kubona iikhamera zokucupha ezahlukahlukeneyo kwizakhiwo ezininzi zokuhlala, izakhiwo zeofisi, kudederhu lweevenkile, iihotele kunye nezinye iindawo ukuthintela ukwenzeka kwemisebenzi engekho mthethweni.
Ngophuhliso oluzinzileyo lwezoqoqosho kunye nobuchwepheshe, ulwazi lwabantu lokubeka iliso lokhuseleko luhlala lusanda, kwaye uhlolo lokhuseleko luyafuneka kuyo nayiphi na indawo.Nangona kunjalo, ukuntsonkotha kophuhliso lwedolophu kwenza inkqubo yokubeka iliso yeendlela zokufikelela zemveli zingakwazi ukuhlangabezana ngokupheleleyo neemfuno, kwaye i-PON yamkelwa.Inkqubo yokubeka iliso yokufikelela kuthungelwano ngokuthe ngcembe idumile.
Njengesixhobo esibalulekileyo sokufikelela kwinkqubo ye-PON, ukhetho lwe-ONU lubalulekile, ngoko ke yiyiphi i-ONU engcono kunye nendlela yokukhetha?
I-ONU iyisixhobo sokuphela komsebenzisi kwizicelo ze-PON kunye ne-high-bandwidth kunye neendleko ze-terminal device eziyimfuneko ekutshintsheni ukusuka kwi "copper cable era" ukuya kwi "optical fiber era".Idlala indima eqinisekileyo kulwakhiwo lwenethiwekhi.
I-ONU yiyunithi yenethiwekhi ye-optical network, esebenzisa i-fiber yeyunithi ukudibanisa kwiofisi ephakathi ye-OLT ukubonelela ngeenkonzo ezifana nedatha, ilizwi kunye nevidiyo.Inoxanduva lokufumana idatha ethunyelwe yi-OLT, iphendula kwimiyalelo ethunyelwe yi-OLT, i-buffering data kwaye iyithumele kwi-OLT.Ifuna ubuntununtunu obuphezulu kwaye kulula ukuyisebenzisa.
Ii-ONU zohlulwe zibe zii-ONU eziqhelekileyo kunye nee-ONU ezine-PoE.Eyangaphambili sesona sixhobo sixhaphakileyo se-ONU kunye nesona sisetyenziswa kakhulu i-ONU.Le yokugqibela inomsebenzi we-PoE, oko kukuthi, inojongano oluninzi lwe-PoE.Ungaqhagamshela iikhamera zokucupha ngokusebenzisa olu nxibelelwano.Basebenza ngokuqhelekileyo kwaye bakhuphe iintambo zombane ezintsonkothileyo.
Ukongeza kwizibuko ze-PoE, ii-ONU ezine-PoE kufuneka zibe ne-PON.Ngale PON, banokudityaniswa kwi-OLT ukwenza inethiwekhi yePON iyonke.
