Abasebenzi bokhuseleko abenze inethiwekhi yePON ngokusisiseko bayazi malunga ne-ONU, esisixhobo sofikelelo esisetyenziswa kuthungelwano lwePON, elilingana nokutshintsha ukufikelela kwinethiwekhi yethu yesiqhelo.
Inethiwekhi yePON yinethiwekhi yamehlo esebenzayo.Isizathu sokuba kuthiwe i-passive kukuba ukuhanjiswa kwe-fiber optical phakathi kwe-ONU kunye ne-OLT ayifuni naziphi na izixhobo zombane.I-PON isebenzisa i-fiber enye ukuxhuma kwi-OLT, edibanisa kwi-ONU.
Nangona kunjalo, i-ONU yokubeka iliso inobunye bayo.Umzekelo, i-ONU-E8024F enomsebenzi we-PoE esanda kuqaliswa ngu-Sushan Weida yi-industrial-grade 24-port 100M EPON-ONU.Ziqhelanise nemeko yokusebenza ye-minus -18 ℃ - ubushushu obuphezulu be-55 ℃.Ifanelekile kubukrelekrele benkqubo kunye nokubeka iliso kwimiba yokhuseleko phantsi kweemfuno ezibanzi zobushushu.Oku akufumaneki kwizixhobo eziqhelekileyo ze-ONU.I-ONU eqhelekileyo ngokuqhelekileyo i-port ye-PON, kwaye ine-port ye-PON kunye ne-port ye-PoE ngexesha elifanayo, elingenzi nje ukuba i-networking ibe bhetyebhetye, kodwa igcina enye i-power supply yekhamera 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 inika amandla kwikhamera nge-port yayo ye-PoE.Akubonakali ngathi lutshintsho olukhulu, kodwa kwezinye iindawo ezikhethekileyo, ezinjengendawo engqongileyo enzima, ukungakwazi ukugrumba iitonela zobonelelo lwamandla, kunye nonikezelo lwamandla olungalunganga, kunenzuzo enkulu.
Ndicinga ukuba lo ngumahluko phakathi kwe-PON kwintsimi yokufikelela kwi-broadband kunye nokubeka iliso.Ngokuqinisekileyo, i-ONU enomsebenzi we-PoE inokusetyenziswa kwakhona kwibala le-broadband.
Nangona usetyenziso lwendlela yokufikelela kwi-PON ekubekeni iliso alubanzi kakhulu ngoku, kunokubonwa ukuba ngophuhliso lwezixeko ezikhuselekileyo kunye nezixeko ezihlakaniphile, ukusetyenziswa kwe-PON yendlela yokufikelela iya kuba yinto eqhubekayo.
