Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber-optic communication systems face challenges in maintaining optimal power levels during link-on events, leading to poor connection or bad communication quality due to inefficiencies in optical transceivers, particularly in high-temperature environments, resulting in increased operational current and reduced lifespan.
Innovation Solution
A method for dynamic power optimization in fiber-optic communication systems involves a first optical transceiver transmitting a power correction request packet to a second transceiver, acquiring a power compensation value based on actual and expected receiving powers, and adjusting the transmitting power to minimize power waste, ensuring normal communication while reducing heat and prolonging device lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the optical transmitting power is reduced to decrease operational current and heat, then the lifespan of light devices is prolonged, but the communication quality may deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of optical transmitting power based on real-time link quality monitoring. The system transitions from static maximum power transmission to dynamic power levels that adapt to connection conditions, allowing reduced power (and thus reduced heat and extended lifespan) when link quality is good, while maintaining reliability when quality deteriorates
Solution Approach 2:
The system employs feedback mechanisms where the receiving end monitors optical signal quality and sends control signals back to the transmitting end. This feedback loop enables the transmitting end to adjust its optical power dynamically, ensuring communication quality is maintained while optimizing power consumption and device lifespan
2Reliability
If the optical transmitting power is increased to ensure normal communication, then the communication quality is maintained, but the operational current increases and heat is generated
Solution Approach 1:
The system dynamically adjusts optical transmitting power based on actual link conditions rather than operating at constant maximum power. When link quality is good, power is reduced to minimize energy consumption and heat generation. When quality deteriorates, power is increased only to the extent necessary to maintain communication, avoiding unnecessary energy waste
Solution Approach 2:
The patent changes the operating parameters of the optical transmitting device dynamically. By adjusting the optical power parameter in response to link quality measurements, the system optimizes the balance between communication reliability and energy consumption, ensuring minimum necessary power usage for maintaining quality
3Reliability
If the optical transmitting power is increased to compensate for poor connection, then the connection quality improves, but the power consumption increases
Solution Approach 1:
The system implements dynamic power adjustment where transmitting power is increased only temporarily and only to the extent necessary to compensate for poor connection conditions. Once link quality improves, power is reduced again, minimizing overall energy loss while maintaining connection quality when needed
Solution Approach 2:
The patent dynamically changes the optical power parameter in response to connection quality measurements. When poor connection is detected, power is increased to restore quality. The system continuously monitors and adjusts this parameter, ensuring power consumption is minimized while maintaining acceptable connection quality

AI summary
A fiber-optic communication system (100, 100) includes a first optical transceiver (100A) and a second optical transceiver (100B). First, the first optical transceiver (100A) is configured to transmit signals to the second optical transceiver (100B) using an optical transmission power having an initial value. When the optical receiving power inputted into the second optical transceiver (100B) is larger than the expected input power of the second optical transceiver (100B), a power compensation value is acquired according to the optical receiving power and the expected input power. The first optical transceiver (100A) is configured adjust its optical transmission power according to the power compensation value and then transmit signals to the second optical transceiver (100B) using the adjusted optical transmission power.
