Communication Apparatus Rate Detection and Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems struggle to establish proper data communication links due to differing data transmission/processing rates between devices, as they cannot automatically adjust to match the rates of connected optical fiber networks, leading to communication failures.
Innovation Solution
A communication apparatus and method that detects the transmitted rate of an input signal by sampling it with a specific frequency, determining the input rate, and adjusting its receiving rate to match, enabling communication at either a first or second rate, higher than the initial rate, using a receiving circuit, detecting circuit, and processing circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of data transmission rate is used before production factory, then the communication apparatus can operate at a fixed rate, but it cannot adapt to optical fiber networks with different data transmission rates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the communication apparatus with multiple possible data transmission rates (125 Mbps and 1250 Mbps) before production. The apparatus is equipped with detection circuits that can identify the actual transmission rate of incoming signals and automatically select the appropriate operating rate, eliminating the need for post-deployment manual reconfiguration while maintaining operational simplicity.
2Productivity
If the communication apparatus operates at a fixed high rate, then it can handle high-speed networks, but it cannot communicate with devices operating at lower rates
Solution Approach 1:
The patent implements dynamics by enabling the communication apparatus to dynamically adjust its operating data transmission rate based on the detected incoming signal rate. The apparatus can switch between 125 Mbps and 1250 Mbps operating modes, allowing it to maintain high productivity when connected to high-speed networks while ensuring compatibility with lower-rate devices through automatic rate adaptation.
3Reliability
If the communication apparatus uses a simple fixed rate configuration, then the device structure remains simple, but it fails to establish proper communication links when rate mismatches occur
Solution Approach 1:
The patent applies feedback by incorporating detection circuits that continuously monitor incoming signals to identify their transmission rate. The system uses this feedback information to automatically adjust its operating rate, ensuring reliable communication link establishment. The feedback mechanism includes sampling the input signal and analyzing its characteristics to determine whether it operates at 125 Mbps or 1250 Mbps, then configuring the apparatus accordingly.
Data Source
AI summary
A communication apparatus with transmitted rate detecting function and the method therefore is provided. The communication apparatus receives an input signal transmitted at a first rate or a second rate from a remote apparatus. The method includes setting the communication apparatus to operate at an initial receiving rate; sampling the input signal by a specific sampling frequency to generate a sample result; estimating the input transmitted rate of the input signal according to the sample result so as to set the receiving rate of the communication apparatus at a working rate; and communicating with the remote apparatus at the working rate. The second rate is higher than the first rate, and the specific sampling frequency is associated with the initial receiving rate.
