OLT: Ibhekisa kwitheminali yomgca we-optical esiyisebenzisayo, kwaye ikwasisixhobo sokugqibela esisetyenziselwa ukudibanisa i-trunk yefiber 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".
OLTsisixhobo seofisi kwi-EPON passive optical network system. Yinkonzo yokubonelela ngeenkonzo ezininzi, ezinokuxhasa iinkonzo ze-IP kunye neenkonzo zendabuko ze-TDM ngexesha elifanayo. 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 idata ethunyelwe nguOLT; Phendula kuluhlu kunye nemiyalelo yolawulo lwamandla ethunyelwe nguOLT; Kwaye wenze uhlengahlengiso oluhambelanayo; Idatha ye-Ethernet yomsebenzisi igcinwe kwaye ithunyelwe kwi-uplink direction kwi-window yokuthumela eyabiwe yiOLT.
