Bisadda indhaha (sidoo kale loo yaqaano aaladda ONU) ee ay bixiso hawlwadeenka gurigeena ku rakiban waxa ay gelisaa shabakadda hawlwadeenka iyada oo u sii marinaysa PON (shabakadda indhaha ee dadban), waxa ay isku xidhaa kala qaybisa aragga, ka dibna waxa ay ku xidhaa dekedda PON ee qalabka OLT ee hawlwadeenka.Xogta borotokoolka gabi ahaanba way ka duwan tahay LAN-dhaqameedka.Cat Optical waxay u beddeshaa xogta PON xogta Ethernet, taasoo ka ciyaarta doorka beddelka borotokoolka, ie gateway.
Nooca bisadaha fudud: waxa loo qaybin karaa EPON ONU, GPON ONU, XPON ONU sida waafaqsan heerka
1. EPON ONU: EPON (Ethernet Passive Optical Network), oo ku salaysan IEEE 802.3ah heerka borotokoolka, waxa uu bixiyaa kor u kaca iyo hoos u dhigista heerka summetrical ee 1.25Gbps.
2. GPON ONU: GPON (Gigabit-Capable PON), ku salaysan ITU-T G.984.x heerka borotokoolka, waxa uu bixiyaa kor u kaca iyo hoos u dhigista heerarka asymmetrical ee 1.244Gbps ee kor isku xidhka iyo 2.488Gbps ee hoos-u-dhaca.
3. XPON ONU: Dual-mode ONU, taageeraya IEEE 802.3ah/ITU-T G.984.x heerka borotokoolka.
