Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical path designs in one wavelength fail to satisfy desired transmission distances and capacities, particularly for large-capacity connections over short distances, leading to unsatisfactory user demands.
Innovation Solution
An optical transmission system with a transmission line design unit that specifies a first transmission mode, acquires information on multiple wavelengths when the initial mode is insufficient, and generates multiplexed optical signals using a multiple-lane processing unit to meet connection requests, involving a wavelength demultiplexing unit for communication between user-side devices and carrier network nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wavelength transmission mode is used to simplify the optical path setting, then the device complexity is reduced, but the transmission distance and capacity requirements cannot be satisfied for large-capacity optical paths
Solution Approach 1:
The patent segments the optical transmission into multiple wavelengths (wavelength division multiplexing), dividing a single complex transmission channel into multiple simpler wavelength channels. This allows the system to handle large-capacity transmission by combining multiple wavelengths while maintaining manageable complexity through automated selection of appropriate wavelength combinations based on transmission distance and capacity requirements
Solution Approach 2:
The patent changes the transmission parameters by selecting from multiple wavelengths and transmission modes based on the specific connection requirements. The control device automatically determines the appropriate wavelength combination and transmission mode parameters to satisfy both transmission distance and capacity requirements, resolving the contradiction between simplified setting and reliable transmission
2Reliability
If multiple wavelengths are used to satisfy large-capacity transmission requests, then the transmission capacity and distance requirements are met, but the device complexity and transmission design difficulty increase
Solution Approach 1:
The patent implements self-service through automated transmission mode selection. The control device automatically determines the appropriate wavelength combination and transmission parameters based on connection requests, eliminating the need for manual transmission design. This self-configuration capability allows multiple wavelengths to be utilized for high-capacity transmission while keeping the operational complexity low
Solution Approach 2:
The system incorporates feedback mechanisms where the control device receives connection request information, automatically determines the appropriate transmission mode and wavelength combination, and configures the optical path accordingly. This closed-loop control eliminates manual design complexity while enabling flexible use of multiple wavelengths to satisfy transmission requirements
