Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asymmetrical data transmission systems are inefficient due to the same technology being used in both transmission directions, leading to high costs and incomplete utilization of data channels, especially when one direction requires high bandwidth and the other low bandwidth.
Innovation Solution
Implementing a fiber-optic link for wideband data transmission in one direction and a non-optical link, such as copper or wireless, for narrowband control signals in the other direction, allowing for cost-effective asymmetrical data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same technology (fiber-optic link) is used for both transmission directions, then reliable data transmission is achieved, but cost increases and bandwidth utilization becomes inefficient
Solution Approach 1:
The bidirectional data transmission channel is segmented into two separate channels: a fiber-optic link for high-bandwidth transmission in one direction and a non-optical link for low-bandwidth control signals in the opposite direction. This segmentation allows each channel to be optimized for its specific bandwidth requirements, avoiding the waste of using high-cost fiber-optic infrastructure for low-bandwidth traffic.
Solution Approach 2:
Different transmission technologies are applied locally to different directions of data flow based on their specific bandwidth requirements. The fiber-optic link is used where high bandwidth is needed, while the non-optical link is used where only low bandwidth is required, creating a locally optimized system that balances performance and cost.
2Productivity
If fiber-optic link is used for both transmission directions, then high bandwidth transmission is enabled, but cost increases due to incomplete utilization of the data channel
Solution Approach 1:
The transmission system is segmented into two independent channels with different technological characteristics. The fiber-optic channel handles high-bandwidth data transmission in one direction, while the non-optical channel handles low-bandwidth control signals in the opposite direction, preventing over-provisioning and optimizing cost-performance ratio.
Solution Approach 2:
The system changes the technical parameters of the transmission channels by selecting different underlying technologies (optical vs. non-optical) based on the bandwidth requirements of each transmission direction, thereby optimizing the cost-performance relationship.
3Productivity
If asymmetric data transmission is implemented with different technologies for each direction, then bandwidth utilization is optimized, but device complexity increases
Solution Approach 1:
The communication system is divided into two separate transmission paths with different technological foundations. This segmentation, while introducing some complexity, enables precise matching of transmission capabilities to actual bandwidth requirements, achieving superior bandwidth utilization efficiency.

AI summary
A communication arrangement and a method are provided for bidirectionally transmitting data between a first communication unit and a second communication unit. The first communication unit and the second communication unit are connected to one another via a fiber-optic link. In addition, the first communication unit and the second communication unit have a nonoptical link between them. Data in one transmission direction is transmitted via the fiber-optic link and data in the other transmission direction is transmitted via the nonoptical link.
