Bisadda indhaha (sidoo kale loo yaqaanONUAaladda) uu bixiyo hawlwadeenka gurigeena ku rakiban waxa uu gelayaa shabakadda hawlwadeenka iyada oo loo marayo PON (shabakadda indhaha ee aan qarsoonayn), waxa uu ku xidhaa kala qaybiyaha indhaha, ka dibna waxa uu ku xidhaa dekedda PON ee hawlwadeenkaOLTqalab. 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 EPONONU, GPONONU, XPONONUsida waafaqsan heerka
1. EPONONU: 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. GPONONU: GPON (Gigabit-Awood 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. XPONONU: dual-modeONU, taageeraya IEEE 802.3ah/ITU-T G.984. x heerka borotokoolka.
