optical distribution network odn (ODN) is an FTTH optical cable network based on PON devices. Its role is to provide an optical transmission channel between the OLT and the ONU, is a physical facility that connects the communication room and user equipment, and is a key component of the Gigabit fiber network. In FTTH network, due to the simpler networking of network equipment, optical distribution network (ODN) has actually become the main body of network investment, accounting for more than 70% of the initial construction investment of FTTH, and the application demand has surged.
