Smart Optical Network Termination Device for Provider-Customer Demarcation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network technologies require complex and costly hardware installations at customer premises for demarcation between provider and customer networks, necessitating frequent updates and maintenance, which is inefficient and costly.
Innovation Solution
A system comprising a smart optical network termination device (NT) at the customer site and a monitoring unit at the provider's point of presence (POP), which implements a demarcation point independent of data rates and optical interfaces, and interacts with the monitoring unit via traffic analysis points for connectivity validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active network termination devices are used to build a clear demarcation between provider network edge and customer CPE, then the demarcation point is clearly defined, but complex and cost intensive hardware installation is needed at customer location
Solution Approach 1:
The patent introduces an intermediary device (optical coupler/TAP) that mediates between the provider network and customer CPE. This intermediary enables clear demarcation and monitoring without requiring complex active termination devices at the customer location, as the monitoring function is distributed to the provider side through the optical coupler.
Solution Approach 2:
The patent replaces the mechanical/electrical active network termination device with an optical-based monitoring system. The optical coupler uses optical field principles to monitor power levels and connectivity without requiring physical access or complex hardware installation at the customer premises, substituting traditional electrical monitoring with optical monitoring.
2Reliability
If active network termination devices are installed at customer premises, then demarcation is established, but frequent maintenance and updates are required when technology changes or service upgrades are needed
Solution Approach 1:
The patent implements a feedback mechanism where the monitoring device continuously monitors optical power levels and connectivity status through the optical coupler. This real-time feedback enables proactive detection of issues and automated monitoring, reducing the need for manual maintenance visits and allowing for remote service upgrades without physical hardware changes at customer locations.
Solution Approach 2:
The monitoring system enables self-service capabilities by automatically detecting connectivity issues, power level changes, and service status without requiring customer intervention or provider maintenance visits. The system can automatically log events, generate alerts, and provide diagnostic information, reducing maintenance time and frequency.
3Adaptability or versatility
If network termination device needs to be replaced, then technology or service changes can be implemented, but all equipment on separate fiber must be reinstalled and end-to-end verification is required
Solution Approach 1:
The patent segments the monitoring function from the network termination function. The optical coupler and monitoring device are separated from the customer CPE, allowing the monitoring infrastructure to remain in place while only the customer-side equipment needs to be upgraded. This segmentation enables technology changes without requiring complete reinstallation of the entire fiber infrastructure.
Solution Approach 2:
The monitoring device is pre-installed and configured at the provider location before service changes are needed. This preliminary setup includes establishing the optical monitoring path through the coupler and configuring the monitoring parameters, so that when service upgrades or technology changes are required, the monitoring infrastructure is already in place to support and verify the changes without requiring end-to-end reinstallation.

AI summary
A system installed in a cross-border area between a provider network of a provider and a customer network of a customer includes: a smart optical network termination device (NT) at a site of the customer, wherein the smart optical NT is configured to implement a demarcation point between the customer network and the provider network, and wherein the smart optical NT is independent of a data rate passing through it and an optical interface connected to it; and a monitoring device located at a point of presence (POP) of the provider network. The smart optical NT is further configured to monitor a coupling of optical power by the customer into the provider network and to interact with the monitoring device via at least one traffic analysis point (TAP) for connectivity validation from the POP to the demarcation point.
