Power Data Transmission Extender Engine Voltage Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-cable power and data transmission techniques, such as Power over Ethernet (PoE), are limited to transmitting power over approximately 100 meters due to voltage drop, requiring separate power sources for devices beyond this distance, thereby increasing cabling needs.
Innovation Solution
An Information Handling System (IHS) with a power/data transmission extender engine that receives power and data via a first cable, stores power in a subsystem, and transmits it via a second cable to extend the transmission distance, using a power storage subsystem and data transmission sub-engine to maintain sufficient power characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If Power over Ethernet (PoE) techniques are used to transmit power and data over a single cable, then the amount of cabling is reduced, but the transmission distance is limited to approximately 100 meters due to voltage drop
Solution Approach 1:
A power extender device is introduced as an intermediary component between the power source and the powered device. This extender receives power through a first cable, stores it in a power storage subsystem (capacitors), and transmits it through a second cable to the powered device, thereby extending the transmission distance beyond the conventional 100-meter limit while maintaining single-cable operation
Solution Approach 2:
The patent changes the voltage parameter by storing power in capacitors that maintain a voltage level (e.g., 48V) sufficient to overcome voltage drop over extended distances. The power storage subsystem ensures that the voltage remains above the minimum threshold (e.g., 42.5V) required by the powered device, enabling transmission beyond standard PoE distance limits
2Length of stationary object
If the cable length is extended beyond 100 meters, then the transmission distance is increased, but the voltage drop causes power degradation to insufficient levels
Solution Approach 1:
The power extender performs preliminary action by storing power in its power storage subsystem before transmission. The capacitors are charged to a sufficient voltage level in advance, ensuring that even after voltage drop over extended cable lengths, the power delivered to the powered device remains above the minimum required threshold
Solution Approach 2:
The power extender acts as a mediator that compensates for voltage drop. It receives degraded power from the first cable, restores it to adequate levels using its power storage subsystem, and delivers sufficient power through the second cable to the powered device, thereby enabling extended transmission distances
3Power
If separate power sources are used for devices beyond 100 meters, then sufficient power is provided, but the amount of cabling and device complexity increases
Solution Approach 1:
The power extender device performs multiple functions: it receives power through a cable, stores power in its power storage subsystem, transmits data, and delivers power to the powered device. This multi-functionality eliminates the need for separate power sources and reduces system complexity while maintaining power sufficiency for extended distance operation
Solution Approach 2:
The patent merges power transmission and data transmission into a single cable system using the power extender. The extender combines the functions of power storage, power transmission, and data transmission in one device, thereby reducing the need for separate power sources and simplifying the overall system architecture

Data Source
AI summary
A power/data transmission extender system includes a power/data transmission extender device that is coupled to a powering device and a powered device. The power/data transmission extender device receives power and data from the powering device via a first power/data cable that is connected to the power/data transmission extender device, and stores at least a portion of the power that was received from the powering device via the first power/data cable in a power storage subsystem that is included in the power/data transmission extender device. The power/data transmission extender device may then transmit the data that was received from the powering device, at least a portion of the power that was received from the powering device, and at least a portion of power that is stored in the power storage subsystem, to the powered device via a second power/data cable that is connected to the power/data transmission extender device.
