Programmable SFP Transceiver for Remote Network Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SFP transceivers lack the diagnostic capabilities to identify and isolate network issues such as delay or loss across the entire or a portion of the network.
Innovation Solution
Incorporating a programmable signal processing module, such as a Field Programmable Gate Array (FPGA) or Application Specific Integrated Circuit (ASIC), into the SFP transceiver to perform service assurance and management functions, including monitoring network traffic, diagnosing issues, and performing remote testing, without requiring changes to the software on the network node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-function transceiver is used, then the device complexity is low, but the adaptability to different network services and management functions is poor
Solution Approach 1:
The transceiver incorporates a programmable signal processing module that can be dynamically reconfigured to perform different service assurance and management functions. This dynamic programmability allows the same hardware to adapt to various network services and diagnostic requirements without requiring physical changes to the device structure.
Solution Approach 2:
The programmable signal processing module enables a single transceiver design to perform multiple functions including service assurance, network monitoring, traffic policing, and various diagnostic tests. This multi-functionality eliminates the need for separate dedicated devices for each function, achieving versatility without proportionally increasing device complexity.
2Reliability
If service assurance and management functions are added to the transceiver, then the diagnostic capability is improved, but the ease of operation deteriorates due to configuration complexity
Solution Approach 1:
The transceiver is designed with self-service capabilities where the programmable module can be remotely configured and programmed through standard network protocols. The device can autonomously perform service assurance functions, monitor network conditions, and execute diagnostic tests without requiring manual intervention or complex local configuration, thereby maintaining ease of operation despite enhanced diagnostic capabilities.
Solution Approach 2:
The patent introduces intermediary management systems and standardized protocols that mediate between the operator and the complex programmable functions. These intermediaries provide simplified interfaces and automated configuration mechanisms, allowing operators to access advanced diagnostic capabilities without directly dealing with the underlying complexity of the programmable signal processing module.
3Extent of automation
If the transceiver is made programmable for remote management, then the service management capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the programmable signal processing capabilities directly into the transceiver module itself, combining what would traditionally be separate functions (transceiver operation and service assurance processing) into a single integrated device. This consolidation achieves remote management capability without requiring additional external processing equipment, thereby limiting the increase in overall system complexity.

AI summary
A small form factor pluggable (“SFP”) transceiver for use in a communications network includes a transmitter adapted to be coupled to the network for supplying signals to the network, a receiver adapted to be coupled to the network for receiving signals from the network, and a programmable signal processing module coupled to the transmitter and the receiver and adapted to be programmed from a remote station coupled to the network. The module can be programmed to perform at least one service or management function on the network.
