Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical splitters are not suitable for sparsely populated regions as they require a large quantity of optical cable resources and are not flexible in handling varying power requirements across different distances, leading to inefficiencies in signal distribution.
Innovation Solution
An optical splitter chip with both uneven and even optical splitting units integrated on the same substrate, allowing for the splitting of signal light into multiple channels of varying power levels, reducing the need for separate splitters and minimizing optical power loss, while enabling flexible power allocation based on distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional even optical splitters are used for sparsely populated regions, then all channels receive equal power, but this leads to inefficient use of optical cable resources and inability to accommodate varying distance requirements
Solution Approach 1:
The patent applies local quality by implementing different splitting ratios for different output channels based on their specific distance requirements. The uneven optical splitting unit divides the input optical signal into multiple output signals with different power levels, where channels farther from the OLT receive higher power and closer channels receive lower power, optimizing power distribution according to local needs
Solution Approach 2:
The patent changes the power parameter of optical signals by using uneven optical splitting units with different splitting ratios. This allows the system to allocate different power levels to different output channels based on distance, transforming the fixed equal-power distribution into a variable power distribution that adapts to varying transmission distances
2Adaptability or versatility
If multiple separate splitters are deployed to handle different power requirements, then power allocation flexibility improves, but device complexity and material costs increase
Solution Approach 1:
The patent merges multiple separate splitters into a single integrated optical splitter device that contains both even and uneven optical splitting units. This unified structure can simultaneously provide equal power distribution for some channels and unequal power distribution for others, eliminating the need for multiple separate splitter devices and reducing overall system complexity
Solution Approach 2:
The patent creates a universal optical splitter that performs multiple functions: it can provide even optical splitting for channels with equal power requirements and uneven optical splitting for channels with varying power requirements. This multi-functional device replaces the need for different specialized splitters, simplifying the overall network architecture
3Ease of manufacture
If conventional tree networking is used in sparsely populated regions, then deployment is simple, but optical cable resource consumption increases significantly
Solution Approach 1:
The patent applies local quality by allocating different power levels to different output channels based on their specific distance requirements from the OLT. This allows for optimized power distribution where farther channels receive more power and closer channels receive less, reducing overall optical power loss and enabling more efficient use of optical cable resources in sparsely populated regions

AI summary
One example optical splitter chip includes a substrate. The substrate is configured with an input port, configured to receive first signal light, an uneven optical splitting unit, configured to split the first signal light into at least second signal light and third signal light, where optical power of the second signal light is different from optical power of the third signal light, a first output port, configured to output the second signal light, an even optical splitting unit group, including at least one even optical splitting unit, configured to split the third signal light into at least two channels of equal signal light, where optical power of the at least two channels of equal signal light is the same, and at least two second output ports, which are in a one-to-one correspondence with the at least two channels of equal signal light.
