Can PTN equipment have an OLT-ONU interface similar to PON?

Hello, friend!

In actual deployment, PTN equipment is deployed on each base station as a wireless backhaul device. However, the OLT distribution density of a PON network is much lower than that of PTN network elements, which are generally distributed in large residential communities, large transmission rooms, or core offices.

This leads to a situation. When there are PTN resources nearby, the ONUs of the PON network still needs to stay close and seek farther and use optical splitting equipment to occupy a separate optical fiber and connect to a far OLT.

If a PON interface can be provided on the PTN equipment to allow ONU access, it is ok whether it is in transparent transmission mode or processing its layer 2 data packets. This move also greatly reduces the repeated construction of OLT and PTN equipment. ONU equipment connected through PTN can still be included in the unified network management of PON.

In fact, the PON interface here is only used as a physical interface the same as the FE GE optical fiber interface.

Thank you!
