Kule mihla, kwizixeko zentlalo, iikhamera zokujonga ngokusisiseko zifakelwa kuzo zonke iikona. Siza kubona iikhamera ezahlukeneyo zokujonga kwiindawo ezininzi zokuhlala, izakhiwo zeeofisi, iivenkile ezinkulu, iihotele nakwezinye iindawo ukuthintela ukwenzeka kwemisebenzi engekho mthethweni.
Ngenxa yophuhliso oluqhubekayo loqoqosho kunye netekhnoloji, ulwazi lwabantu ngokubeka iliso kukhuseleko luyanda rhoqo, kwaye ukubeka iliso kukhuseleko kuyadingeka naphi na. Nangona kunjalo, ubunzima bophuhliso lwedolophu benza inkqubo yokubeka iliso yeendlela zokufikelela zemveli ingakwazi ukuhlangabezana ngokupheleleyo neemfuno, kwaye i-PON iyasetyenziswa. Inkqubo yokubeka iliso yokufikelela kwinethiwekhi iye yathandwa kancinci kancinci.
Njengesixhobo sokufikelela esibalulekileyo kwinkqubo ye-PON, ukukhetha i-ONU kubalulekile, ngoko ke yeyiphi i-ONU engcono kwaye ungayikhetha njani?
I-ONU sisixhobo esisetyenziswa ngabasebenzisi bezicelo ze-PON kunye nesixhobo sesiphelo esine-bandwidth ephezulu nesingabizi kakhulu esifunekayo ekutshintsheni ukusuka "kwixesha leentambo zobhedu" ukuya "kwixesha leentambo zokukhanya". Idlala indima ebalulekileyo ekwakheni inethiwekhi.
I-ONU yiyunithi yenethiwekhi ye-optical, esebenzisa i-unit fiber ukuqhagamshela kwi-central office OLT ukubonelela ngeenkonzo ezifana nedatha, ilizwi, kunye nevidiyo. Inoxanduva lokufumana idatha ethunyelwe yi-OLT, ukuphendula kwimiyalelo ethunyelwe yi-OLT, ukubhafa idatha kunye nokuyithumela kwi-OLT. Ifuna uvakalelo oluphezulu kwaye kulula ukuyisebenzisa.
Ii-ONU zahlulwe zaba zii-ONU eziqhelekileyo kunye nee-ONU ezine-PoE. Eyokuqala sesona sixhobo siqhelekileyo se-ONU kwaye sesona sisetyenziswa kakhulu yi-ONU. Eyokugqibela inomsebenzi we-PoE, oko kukuthi, inee-interfaces ezininzi ze-PoE. Ungaqhagamshela iikhamera zokujonga ngezi ndawo. Zisebenza ngokuqhelekileyo kwaye zisusa iingcingo zombane ezintsonkothileyo.
Ukongeza kwiiports zePoE, ii-ONU ezinePoE kufuneka zibe nePON. Ngale PON, zinokuqhagamshelwa kwi-OLT ukuze zenze inethiwekhi yePON iyonke.
