Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical communication devices exhibit an asymmetric distribution of ports on their first and second surfaces, leading to inefficient utilization of optical switches due to unequal port requirements, resulting in unused portions and reduced user accommodation rates.
Innovation Solution
An optical communication device with a light distribution unit featuring symmetric port allocation on both surfaces, utilizing a first surface for subscriber device ports and a second surface for other signal ports, and a control unit to manage connections between these ports, enabling efficient utilization of optical switches.

Engineering Contradiction Analysis
1Productivity
If conventional optical communication devices use asymmetric port allocation with subscriber device ports on one surface and other signal ports on the other surface, then the device can process signals electrically only when necessary, but the port distribution becomes asymmetric leading to inefficient utilization of optical switches and reduced user accommodation rates
Solution Approach 1:
The patent applies asymmetry principle by intentionally creating asymmetric port allocation where subscriber device ports are concentrated on one surface while other signal ports (uplink, downlink, loopback) are allocated on the other surface. This asymmetric design enables efficient optical switch utilization by matching port requirements to actual signal flow patterns, thereby resolving the contradiction between productivity and device complexity through purposeful asymmetric arrangement rather than uniform distribution
2Loss of time
If optical switches are used to relay optical signals between subscriber devices, then communication delay is reduced compared to electrical processing, but asymmetric port requirements cause unused portions of the optical switch and lower accommodation capacity
Solution Approach 1:
The patent applies local quality principle by assigning different port types to different locations (surfaces) of the optical communication device based on their specific functions. Subscriber device ports are localized to one surface while uplink/downlink/loopback ports are localized to the other surface. This localized quality assignment optimizes optical switch utilization by matching the spatial distribution of ports to the actual signal routing requirements, thereby reducing communication delay while maximizing optical switch accommodation capacity
