1Volume of moving object
If optical transmitting devices are arranged in an alternating manner on the substrate, then the internal space utilization is improved and device size is reduced, but the structural complexity increases
Solution Approach 1:
The patent applies alternating arrangement of optical transmitting devices in different spatial dimensions on the substrate. Specifically, odd-numbered optical transmitting devices are arranged on one side of the substrate while even-numbered devices are arranged on the other side, creating a three-dimensional alternating pattern that maximizes space utilization and reduces overall module size.
Solution Approach 2:
The patent segments the optical transmitting devices into two groups based on their position: odd-numbered devices (first, third, fifth, etc.) are placed on one side of the substrate while even-numbered devices (second, fourth, sixth, etc.) are placed on the opposite side. This segmentation enables efficient space utilization while maintaining manageable structural complexity through systematic organization.
2Speed
If optical fiber transmission system is used instead of electrical I/O signaling, then transmission speed and distance are improved, but the device complexity and integration difficulty increase
Solution Approach 1:
The patent merges multiple optical transmitting devices and the optical receiving device onto a single substrate, integrating the entire optical transmission system into one compact module. This consolidation reduces the number of separate components and simplifies the overall system architecture while maintaining high-speed optical transmission capabilities.
Solution Approach 2:
The substrate serves multiple functions simultaneously: it provides mechanical support for mounting the optical devices, provides electrical interconnections between devices, and provides structural integration for the entire module. This multi-functionality reduces the need for additional components and simplifies the overall system design.
