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.
