Existing network communication systems face challenges in controlling hardware and software within optical networks without affecting optical traffic or adding additional load, particularly in transmitting instructions and diagnostics between modules on opposite ends of an optical fiber link.
Innovation Solution
A system and method that utilize a Transceiver to Transceiver Digital Optical Command (T2DOC) interface to transmit instructions and diagnostics between modules on opposite ends of an optical fiber link, enabling independent operation and processing, while maintaining unaffected optical traffic and avoiding additional load, using techniques such as forward error correction and automatic bit error ratio adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network control methods are used to control hardware and software within optical networks, then control functionality is achieved, but optical traffic is affected and additional load is added to the system
Solution Approach 1:
The patent segments the optical signal into multiple channels, dedicating specific wavelengths to control traffic while other wavelengths carry data traffic. This segmentation allows control functionality to operate independently without affecting optical data traffic, resolving the contradiction between achieving control and avoiding impact on optical traffic.
Solution Approach 2:
The patent introduces an intermediary mechanism using optical add-drop multiplexers and dedicated control wavelengths to mediate between control traffic and data traffic. This intermediary allows control commands to be injected and extracted from the optical stream without interfering with the main data flow, thus achieving control functionality while preventing harmful impacts on optical traffic.
2Ease of operation
If control instructions are transmitted between modules on opposite ends of an optical fiber link, then far-end network control is enabled, but the system complexity increases
Solution Approach 1:
The patent implements a universal control mechanism where the same optical infrastructure and protocol can be used for various control functions including traffic monitoring, error detection, and remote module control. This multi-functionality approach enables far-end network control without proportionally increasing system complexity, as the same components serve multiple control purposes.
Solution Approach 2:
The patent enables modules to autonomously process and execute control instructions received through the optical link, with each module capable of self-diagnosis and self-adjustment based on received control traffic. This self-service capability reduces the need for complex external control systems, thereby enabling far-end control while limiting the increase in overall system complexity.
3Measurement precision
If diagnostic monitor data is transmitted and processed between modules, then network diagnostics and control are improved, but additional processing load is added
Solution Approach 1:
The patent implements partial monitoring where only critical parameters and error conditions are continuously monitored and transmitted, rather than monitoring all possible parameters at full resolution. This selective monitoring approach improves diagnostic capability for critical issues while minimizing the processing load and energy consumption associated with transmitting and analyzing comprehensive diagnostic data.
