Optical Transceiver Segmentation for Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical transceivers face issues with optical and electrical crosstalk between channels, high manufacturing costs due to precise alignment requirements of optical fiber ends with light receiving and emitting devices, and small gaps between electrical lines leading to increased crosstalk.
Innovation Solution
The optical transceiver design incorporates single channel light receiving and emitting assemblies within a case, performing opto-electric and electro-optic conversions, which eliminates crosstalk and reduces manufacturing complexity by allowing wider electrical line gaps and eliminating the need for precise fiber end alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light receiving device arrays and light emitting device arrays are used in conventional optical transceivers, then optical signals can be converted to electrical signals and vice versa, but optical crosstalk occurs between adjacent channels
Solution Approach 1:
The patent divides the optical transceiver into separate single channel light receiving assemblies and single channel light emitting assemblies, with each assembly handling one optical channel independently. This segmentation physically isolates adjacent channels, preventing optical crosstalk while maintaining the ability to convert optical signals to electrical signals and vice versa for each channel
2Adaptability or versatility
If light receiving device arrays and light emitting device arrays are used in conventional optical transceivers, then optical signal conversion is enabled, but electrical crosstalk occurs due to small gaps between electrical lines
Solution Approach 1:
By segmenting the transceiver into separate single channel assemblies, the patent allows electrical lines for adjacent channels to be routed with greater separation. Each assembly's electrical connections are isolated, enabling wider gaps between adjacent electrical lines and reducing electrical crosstalk while preserving optical signal conversion functionality
3Adaptability or versatility
If end parts of optical fiber array are arranged to face light receiving device arrays and light emitting device arrays in conventional optical transceivers, then optical signal reception and transmission are achieved, but manufacturing costs increase due to difficult precise alignment
Solution Approach 1:
The patent separates optical fibers into individual single channel light receiving assemblies and single channel light emitting assemblies. This segmentation allows each optical fiber to be connected independently to its corresponding assembly, eliminating the need for precise alignment of multiple fiber ends simultaneously and reducing manufacturing complexity and cost while maintaining optical signal reception and transmission capabilities
