Optical Module Connector for Fiber-Linked Power Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Power over Ethernet (PoE) systems are limited in range and power capacity, requiring local power sources for distances beyond 100 meters and unable to supply the higher power demands of certain devices.
Innovation Solution
Power delivery through an optical system using fiber cabling to transmit power over greater distances (up to 10 km) and at higher capacities (up to several kilowatts) by integrating power with fiber optic transceivers, enabling power delivery to network devices beyond the traditional 100 m range of PoE systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional PoE systems are used to deliver power over cables, then power delivery is simple and compatible with existing infrastructure, but the delivery distance is limited to about 100 meters and power capacity is limited
Solution Approach 1:
The patent combines fiber optic data transmission with electrical power transmission in a single integrated cable system. The connector couples both optical fibers and electrical wires to the optical module, merging two previously separate functions (data and power delivery) into one unified interface, thereby achieving extended power delivery distance without sacrificing power capacity
Solution Approach 2:
The optical module is designed to perform multiple functions: it handles both optical data transmission and electrical power reception. The universal interface supports both PoE and non-PoE devices, and can deliver power over distances up to 10 km while providing power capacity of several kilowatts, making the system adaptable to various power and data requirements
2Length of stationary object
If fiber optic cables are used for data transmission, then data transmission over long distances is achieved, but power cannot be delivered through the fiber optic cable itself
Solution Approach 1:
The patent merges fiber optic data transmission capability with electrical power delivery capability into a single cable assembly. The connector simultaneously couples optical fibers for data transmission and electrical wires for power delivery, making the system versatile enough to handle both functions over extended distances
Solution Approach 2:
The optical module acts as an intermediary device that converts optical data signals to electrical signals while also receiving electrical power through the same connector interface. This mediator enables the system to deliver both data and power through what would traditionally be separate infrastructure
3Device complexity
If power is delivered through a single integrated system, then infrastructure complexity is reduced and local power sources are eliminated, but the system must handle both optical and electrical signals simultaneously
Solution Approach 1:
The patent consolidates power distribution infrastructure by eliminating the need for separate local power sources and electrical wiring. The integrated system delivers both data and power through a single cable connection, reducing infrastructure complexity despite the technical challenge of handling multiple signal types

AI summary
An apparatus includes a connector for coupling a cable comprising at least one optical fiber and at least one electrical wire to an optical module at a network communications device, the connector comprising an electrical contact plate for engagement with an electrical contact on the optical module, and a ferrule for receiving the at least one optical fiber. The electrical contact plate is configured for electrically coupling the at least one electrical wire to the electrical contact on the optical module for delivery of power through the optical module.
