2.2 Product Operation Introduction

The dual-mode ONU is a "combination" of GPON and EPON ONU. Compared with
the single-mode EPON/GPON ONU, the main difference lies in the registration process.
The dual-mode ONU adds a pre-judgment to the current application system (EPON/GPON).
That is, the dual-mode ONU first switches mode, and then starts and completes registration
process in the corresponding mode. When the ONU runs normally in the current system,
its configuration and processing of various messages are basically the same as single-
mode EPON/GPON ONU.
This product mode switch depends on the packet sent by the front-end OLT device to
the ONU. When ONU receives OAM message sent by the EPON OLT, the ONU
automatically switches to the EPON mode after detecting it. In this case, the ONU can be
regarded as the EPON ONU. When the ONU receives OMCI message sent by the GPON
OLT, the ONU automatically switches to the GPON mode after detecting it. In this case, the
ONU can be used as the GPON ONU.
