SFP-NID Integrating Network Demarcation Into Optical Transceivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network demarcation devices (NIDs) are bulky, require external power, and are costly to install and maintain, limiting their deployment and management efficiency in network connectivity and service monitoring.
Innovation Solution
The development of a Small Form Factor Pluggable Network Identification Device (SFP-NID) that integrates NID functionality into SFP modules, utilizing internal power and minimizing size, enabling advanced functions like OAM, media conversion, and in-band management without external power supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional NID devices are used, then network monitoring and management capabilities are provided, but the devices are bulky, require external power, and are costly to install and maintain
Solution Approach 1:
The patent combines the NID functionality with the optical transceiver module into a single integrated unit. The SFP-NID integrates network demarcation, OAM monitoring, and media conversion functions within the compact SFP form factor, eliminating the need for separate external NID devices and power supplies.
Solution Approach 2:
The SFP-NID serves multiple functions simultaneously: it acts as a network demarcation point, provides OAM monitoring capabilities, performs media conversion between optical and electrical signals, and enables in-band management. This multi-functionality replaces what previously required multiple separate devices.
2Reliability
If traditional NID devices are deployed, then service delivery monitoring is enabled, but installation and maintenance costs increase
Solution Approach 1:
The SFP-NID utilizes power from the host equipment through the existing electrical interface, eliminating the need for external power supplies. This self-powered design reduces installation complexity and operational costs, as no separate power wiring or power management is required.
3Volume of moving object
If SFP-NID is used, then device size is minimized and external power is eliminated, but advanced functions like OAM and media conversion must be integrated
Solution Approach 1:
The SFP-NID nests the network demarcation and monitoring functions within the existing SFP optical transceiver structure. The NID functionality is implemented as additional circuitry integrated into the SFP module, utilizing the same physical footprint and power resources.
