Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-ONU ihlukaniswe yaba iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi ye-passive optical. Ngokuvamile, okokusebenza okufakwe izamukeli zamehlo, ama-uplink optical transmitters, nama-amplifiers amaningi amabhuloho okuqapha inethiwekhi kubizwa ngokuthi i-optical node. I-PON isebenzisa i-optical fiber eyodwa ukuze ixhume ku-OLT, bese i-OLT ixhunywe ku-ONU. I-ONU ihlinzeka ngezinsizakalo ezifana nedatha, i-IPTV (I-Interactive Internet TV), izwi (lisebenzisa i-IAD, Idivayisi Yokufinyelela Ehlanganisiwe), futhi ibona ngempela izinhlelo zokusebenza "zokudlala kathathu".
Qaphela: Singahlinzeka ngamasampula mahhala
Izici zomkhiqizo:

19. sekela imodi ekabili ye-GPON / EPON
Izici zembobo:
1. I-PON: xhuma okokusebenza kwe-OLT ekugcineni komthombo ngomugqa wefiber optical
2. Imbobo ye-Ethernet: ixhunywe kumishini eseceleni yomsebenzisi ngekhebula lenethiwekhi ephothiwe, i-lan 1 isivinini ngu-10/100/1000 m, i-adaptive, lan 2 - lan 4 Izinga lembobo liyi-10 / 100 M eliguqukayo
3. Inkinobho yokusetha kabusha: qala kabusha okokusebenza; Cindezela futhi ubambe ngaphezu kwamasekhondi angu-3 futhi isistimu izobuyela kokumisiwe kwasefekthri 4. Inkinobho ye-LED: Inkomba ye-LED ivuliwe/ivaliwe
5. Iswishi yamandla: vula / vala
6. Isixhumi esibonakalayo samandla: sixhunywe kugesi wangaphandle
Izici ze-Optical:
1. ukwesekwa kwe-wavelength division multiplexing ubuchwepheshe, i-fiber eyodwa ye-dual wave bidirectional transmission
