Network Termination Apparatus Segmentation for FTTP Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for connecting customer premises to external telecommunications networks, particularly in the context of fibre to the premises (FTTP), face challenges such as complexity, user-friendliness, health and safety concerns, and the need for flexible upgradeability and maintenance, especially for residential customers, while ensuring minimal disruption and reliability of the network.
Innovation Solution
The apparatus separates the network termination equipment into two modules, with the network operator module located externally and the customer module internally, connected by a data bus, allowing the network operator to access and control the external network components without entering the premises, while the customer can manage their own internal components, enhancing accessibility, safety, and upgradeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical fibre termination equipment is installed at customer premises, then telecommunications bandwidth and performance are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The optical network termination system is divided into two separate modules: a network operator module containing the optical network terminal and management interfaces, and a customer module with user-friendly interfaces. This segmentation allows the complex optical fibre termination functionality to be provided while hiding the complexity from customers, who only interact with the simplified customer module.
2Adaptability or versatility
If customers are allowed to access and modify optical fibre equipment, then upgradeability and customization are improved, but safety risks and network disruption risks increase
Solution Approach 1:
The system separates customer-accessible functions from network-critical functions into distinct modules. The customer module provides upgradeability and customization for customer premises equipment, while the network operator module protects the optical fibre network from unauthorized access. This segmentation enables customers to modify their equipment without exposing the optical fibre infrastructure to safety risks.
Solution Approach 2:
The network operator module acts as an intermediary between the optical fibre network and customer equipment. It provides controlled interfaces that allow customer customization and upgrades while maintaining safety protocols and preventing direct access to the optical fibre infrastructure, thus eliminating laser hazards and fibre breakage risks.
3Reliability
If network operator maintains full control over termination equipment, then network reliability is improved, but ease of operation and customer autonomy deteriorate
Solution Approach 1:
The termination system is segmented into a network operator module that maintains control over network reliability and a customer module that provides ease of operation and autonomy. The network operator module handles critical functions like optical fibre connection and network monitoring, while the customer module enables customers to independently configure and upgrade their own equipment.
Solution Approach 2:
The network operator module serves as an intermediary that ensures network reliability while enabling customer autonomy. It provides standardized interfaces and protocols that allow customer modules to operate independently without compromising network integrity, thus achieving both reliability and ease of operation.
4Speed
If optical fibre is routed through premises, then bandwidth is improved, but health and safety hazards increase due to laser exposure and fibre breakage
Solution Approach 1:
The network operator module acts as an intermediary that manages optical fibre routing and laser exposure risks. It incorporates safety features such as laser safety interlocks, fibre break detection, and controlled optical signal emission, thereby enabling high-bandwidth optical fibre connections while protecting customers from laser hazards and fibre breakage.
5Adaptability or versatility
If full optical termination equipment is installed, then future-proofing and capabilities are improved, but cost increases
Solution Approach 1:
The optical termination system is segmented into essential network operator functions and optional customer functions. Customers can choose to install only the minimum required network operator module for basic connectivity, or add customer modules for enhanced capabilities. This segmentation allows future-proofing through modular additions while controlling initial costs.
Solution Approach 2:
Customers can implement partial optical termination with only the essential network operator module for basic high-speed connectivity, avoiding the cost of full-featured equipment. The system is designed to support incremental upgrades, allowing customers to add capabilities over time rather than requiring full equipment installation upfront.
