Abantu bokhuseleko abaye basebenza kuthungelwano lwe-PON bayayazi i-ONU, esisixhobo sokufikelela kwi-terminal esisetyenziswa kuthungelwano lwePON, elilingana nokutshintsha ukufikelela kwinethiwekhi yethu yesiqhelo.
Inethiwekhi ye-PON yinethiwekhi yamehlo esebenzayo.Isizathu sokuba kuthiwe i-passive kukuba ukuhanjiswa kwefiber optical phakathi kwe-ONU kunye ne-OLT ayifuni naziphi na izixhobo zamandla.I-PON isebenzisa i-fiber eyodwa ye-optical ukudibanisa kwi-OLT, kwaye i-OLT idibaniswe ne-ONU.
Nangona kunjalo, i-ONU yezempilo inobunye bayo.Inkqubo inokuqonda kuphela kwaye ibeke iliso kwiimeko zokhuseleko phantsi kweemfuno ezibanzi zobushushu.Oku akufumaneki kwizixhobo eziqhelekileyo ze-ONU.I-ONU eqhelekileyo liqosha le-PON, kwaye nayo inePON.Kwaye i-port ye-POE, kwaye ine-PON port kunye ne-port ye-PoE ngexesha elifanayo, elingenzi nje ukuba inethiwekhi iguquguquke, kodwa igcina amandla ongezelelweyo kwikhamera yokucupha.
Umahluko omkhulu phakathi kwe-ONU eqhelekileyo kunye ne-ONU exhasa i-PoE kukuba yangaphambili inokusetyenziswa kuphela njengeyunithi yenethiwekhi ye-optical ukubonelela ukuhanjiswa kwedatha.Eyangaphambili ayikwazi ukuhambisa idatha kuphela, kodwa inokuxhuma kwikhamera ngokusebenzisa i-port yayo ye-PoE ukubonelela amandla.Isenokungabonakali ngathi lutshintsho olukhulu, kodwa kwezinye iindawo ezikhethekileyo, njengendawo embi, ukungakwazi ukumba unikezelo lwamandla, unikezelo lwamandla olungafanelekanga, njl. njl., luneenzuzo ezinkulu.
Ndicinga ukuba lo ngumahluko phakathi kwe-PON kwintsimi yokufikelela ngokukhawuleza kunye nokubeka iliso.Ngokuqinisekileyo, i-ONU enomsebenzi we-POE inokusetyenziswa kwakhona kwibala le-broadband.
Nangona ukusetyenziswa kwendlela yokufikelela kwi-PON ekubekeni iliso akubanzi kakhulu, kunokubonwa ukuba ngophuhliso lwezixeko ezikhuselekileyo kunye nezixeko ezihlakaniphile, ukusetyenziswa kweendlela zokufikelela kwi-PON kuya kuba yinto eqhubekayo.
