Optical Network DPU Flexible Backhaul Model Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical network deployments require manual replacement and configuration of Distribution Point Units (DPUs) to switch between different backhaul models, leading to labor-intensive and costly management, development, and maintenance, as well as the need for suppliers to develop and maintain separate hardware and software for each model.
Innovation Solution
A method and device that enable flexible switching between multiple backhaul models by remotely controlling the DPU and Persistent Management Agent (PMA) to automatically store and restore configuration information, allowing the DPU to support all backhaul models on a single device without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual replacement and configuration of DPUs is used to switch between backhaul models, then each backhaul model can be reliably supported, but labor costs and management complexity increase significantly
Solution Approach 1:
The DPU is designed to support multiple backhaul models (TR-167 and TR-156) on a single device through software configuration rather than requiring separate hardware for each model. The device can dynamically switch between different backhaul models by receiving configuration messages from the OLT, eliminating the need for manual hardware replacement while maintaining reliable support for each model through proper software activation.
2Adaptability or versatility
If separate hardware and software are developed for each backhaul model, then model-specific requirements are met, but development and maintenance costs increase
Solution Approach 1:
A single DPU hardware platform is developed with the capability to support multiple backhaul models through software configuration. The device receives identification messages from the OLT indicating which backhaul model to activate, allowing the same hardware to adapt to different models without requiring separate development cycles or maintenance streams for each model.
Solution Approach 2:
The system changes operational parameters (backhaul model configuration) through software rather than changing physical hardware parameters. By receiving configuration messages that indicate which backhaul model to use, the DPU adjusts its operational parameters to match the required model, eliminating the need for separate hardware variants.
3Manufacturing precision
If DPUs are manually configured when switching backhaul models, then configuration accuracy can be ensured, but deployment time and operational complexity increase
Solution Approach 1:
The DPU automatically receives and processes configuration messages from the OLT that indicate which backhaul model to activate. Instead of requiring manual configuration by operators, the device self-configures by parsing the received messages and activating the appropriate backhaul model, ensuring accurate configuration while dramatically reducing deployment time.
Solution Approach 2:
The system implements a feedback mechanism where the OLT sends identification messages to the DPU indicating the target backhaul model. The DPU parses these messages and automatically configures itself accordingly, creating a closed-loop system that ensures configuration accuracy through automated feedback from the network management system.

AI summary
Embodiments of the present disclosure relate to a method and an optical communication device implemented in an optical network and a computer-readable storage medium. In the method described herein, a distribution point unit (DPU) of the optical network receives a message comprising an identification of a target backhaul model from an Optical Line Terminal (OLT) in the optical network. The received message is parsed to obtain the identification of the target backhaul model. The target backhaul model indicated by the identification is used to communicate with the OLT. In this way, the DPU is compatible with many types of backhaul models and is capable of flexibly switching between the many types of backhaul models.
