I-OLT: Ibhekisa kwitheminali yomgca we-optical esiyisebenzisayo, kwaye ikwasisixhobo sokugqibela esisetyenziselwa ukudibanisa isiqu sefiber optical.
I-ONU: I-ONUibhekisa kwiyunithi yomsebenzi womnatha obonakalayo.I-ONUyahlulwe ikakhulu kwiyunithi yenethiwekhi esebenzayo kunye neyunithi yothungelwano engabonakaliyo.Ngokubanzi, izixhobo ezixhotyiswe ngokujongwa kwenethiwekhi kubandakanya i-optical receiver, i-uplink optical transmitter kunye ne-amplifiers ezininzi zebhulorho zibizwa ngokuba yi "optical node".
I-OLT sisixhobo seofisi kwi-EPON passive optical network system.Liqonga elibonelela ngeenkonzo ezininzi, elinokuxhasa iinkonzo ze-IP kunye neenkonzo zeTDM zemveli ngexesha elinye.Sisixhobo esibekwe kumda wothungelwano lommandla we-metropolitan kunye nokuphuma kwinethiwekhi yokufikelela kuluntu, enokuthi idibanise iinkonzo zokufikelela kwaye ihanjiswe kwinethiwekhi ye-IP ngokulandelanayo.
II-ONUI-1001i uplink idibanisa kwiofisi ephakathi nge-port ye-GEPON, kwaye i-downlink inokubonelela nge-gigabit Ethernet port kubasebenzisi ngabanye okanye abanye abasebenzisi.Njengesisombululo sexesha elizayo seFTTx,I-ONUI-1001i inikezela ngelizwi elinamandla, idatha yesantya esiphezulu kunye neenkonzo zevidiyo nge-GEPON ye-fiber eyodwa.I-ONUumsebenzi: khetha ukufumana idatha ethunyelwe yiOLT;Phendula kuluhlu kunye nemiyalelo yolawulo lwamandla ethunyelwe yiOLT;Kwaye wenze uhlengahlengiso oluhambelanayo;Idatha ye-Ethernet yomsebenzisi igcinwe kwaye ithunyelwe kwi-uplink direction kwi-window yokuthumela eyabiwe yi-OLT.
