Bit Rate Supervising Unit for Optical Data Pulse Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in controlling and supervising the bit rate of data transmission over optical conduction paths, as current methods, such as low pass filters, are difficult to produce, expensive, and do not provide a sharp limit between operational and non-operational transmission speeds, leading to potential overuse by clients without operator awareness.
Innovation Solution
A supervising unit is introduced that estimates or determines the bit rate of data pulses and compares it to a predetermined value, allowing for measures such as stopping transmission or annotating usage, eliminating the need for costly and complex filters by directly managing bit rate through a micro-controller and network management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If low pass filters are used to control transmission speed, then the highest possible speed of transmission is controlled, but the filter production becomes expensive and complicated
Solution Approach 1:
The patent replaces the mechanical/physical low pass filter system with an electronic supervising unit that measures and controls transmission speed through electronic means. The supervising unit detects the bit rate of incoming data pulses and compares it against a predetermined maximum value, then generates control signals to enforce the speed limit, substituting complex filter hardware with a simpler electronic measurement and control system.
2Speed
If controllable filters are used to limit bandwidth, then transmission speed is controlled, but the device complexity increases
Solution Approach 1:
The patent extracts the control function from the filter itself and places it in a separate supervising unit. Instead of making the filter controllable and complex, the invention takes out the speed control functionality and implements it independently through measurement and comparison operations in the supervising unit, which then enforces the limit through control signals.
Solution Approach 2:
The supervising unit acts as an intermediary between the data transmission system and the speed control mechanism. It measures the bit rate of incoming pulses, compares this measurement with the predetermined maximum value, and generates control signals based on this comparison, serving as a mediator that simplifies the overall control architecture.
3Speed
If filters are used to limit bit rate, then transmission is controlled, but sharp limits between operational and non-operational speeds are not achieved
Solution Approach 1:
The patent implements a feedback mechanism where the supervising unit continuously measures the actual bit rate of incoming data pulses and compares it against the predetermined maximum value. Based on this comparison feedback, the system can detect when the bit rate exceeds the limit and generate appropriate control signals, providing precise and sharp enforcement of the speed limit rather than gradual attenuation.

AI summary
The invention concerns an arrangement for supervising and/or controlling the bit rate of data pulses that are transmitted from a transmitter (16) to at least one optical conduction path (22). The transmitter (16) has an input side (18) which receives electrical pulses from an electric connection (14) and an output side (20) from which light pulses are transmitted in response to the received electrical pulses. The arrangement comprises a supervising unit (24) with at least one input (26) which is suited to be connected to said electric connection (14). The supervising unit (24) is arranged to estimate or determine the bit rate of the pulses that are received at said input (26). The arrangement is arranged to carry out at least one measure which depends on the estimated or determined bit rate.
