Abasebenzi bokhuseleko abaye benza inethiwekhi ye-PON bayazi nge-ONU, esisixhobo sokufikelela esisetyenziswa kwinethiwekhi ye-PON, esilingana neswitshi yokufikelela kwinethiwekhi yethu eqhelekileyo.
Inethiwekhi yePON yinethiwekhi ye-optical engasebenziyo. Isizathu sokuba kuthiwe ayisebenzi kukuba ukudluliselwa kwefayibha ye-optical phakathi kwe-ONU kunye ne-OLT akudingi zixhobo zombane. I-PON isebenzisa ifayibha enye ukuqhagamshela kwi-OLT, ethi emva koko iqhagamshelane ne-ONU.
Nangona kunjalo, i-ONU yokubeka esweni inokwahluka kwayo. Umzekelo, i-ONU-E8024F enomsebenzi we-PoE osandul’ ukuqaliswa nguSushan Weida yi-EPON-ONU yomgangatho we-24-port eyi-100M EPON-ONU. Ziqhelanise nendawo yokusebenza ye-minus -18 ℃ – ubushushu obuphezulu be-55 ℃. Ifanelekile kwiindlela zobukrelekrele benkqubo kunye nokubeka esweni iimeko zokhuseleko phantsi kweemfuno zobushushu obubanzi. Oku akufumaneki kwizixhobo eziqhelekileyo ze-ONU. I-ONU eqhelekileyo ngokubanzi yi-PON port, kwaye ine-PON port kunye ne-PoE port ngaxeshanye, nto leyo engenzi nje kuphela ukuba inethiwekhi ibe bhetyebhetye ngakumbi, kodwa ikwagcina nombane omnye kwikhamera yokubeka esweni.
Umahluko omkhulu phakathi kwe-ONU eqhelekileyo kunye ne-ONU exhasa i-PoE kukuba eyokuqala ingasetyenziswa kuphela njengeyunithi yenethiwekhi ye-optical ukubonelela ngokudluliselwa kwedatha. Eyokuqala ayinako ukudlulisa idatha kuphela, kodwa ikwabonelela ngombane kwikhamera ngezibuko layo le-PoE. Akubonakali ngathi lutshintsho olukhulu, kodwa kwezinye iindawo ezikhethekileyo, ezifana neendawo ezinzima, ukungakwazi ukumba imigudu yokunikezelwa kombane, kunye nokunikezelwa kombane okungathandekiyo, inenzuzo enkulu.
Ndicinga ukuba lo ngumahluko phakathi kwe-PON kwicandelo lokufikelela kwi-broadband kunye nokubeka esweni. Kakade ke, umsebenzi we-ONU one-PoE ungasetyenziswa nakwicandelo le-broadband.
Nangona ukusetyenziswa kwendlela yokufikelela kwi-PON esweni kungabanzi kangako okwangoku, kunokubonwa ukuba ngophuhliso lwezixeko ezikhuselekileyo kunye nezixeko ezikrelekrele, ukusetyenziswa kwendlela yokufikelela kwi-PON kuya kuba yinto eqhelekileyo.
