The present disclosure relates generally to information handling systems, and more particularly to transmitting data optically along with power between information handling systems via a single cable.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Information handling systems such as, for example, switch devices, are sometimes configured to transmit data and power over a single cable to powered devices. For example, Power over Ethernet (PoE) is a term used to describe standard or ad-hoc systems that pass electrical power along with data over a twisted pair Ethernet cable that utilizes electrically conducting copper wires to transmit both data and electrical power, allowing a single cable to provide both a data connection and electric power to powered devices such as PoE wireless access point devices, PoE Internet Protocol (IP) camera devices, PoE Voice over IP (VoIP) phone devices, and/or other PoE powered devices known in the art. Furthermore, the powered devices discussed above continue to require increased data transmission bandwidth, which is a trend that is expected to continue into the future.
While traditional Ethernet cabling such as Cat5 Ethernet cabling, Cat6 Ethernet cabling, and Cat7 Ethernet cabling has been relatively capable of providing the required bandwidth for the current generation of powered devices, PoE powered devices are known to be generally limited in the amount of data they are capable of transmitting, which is due to the capabilities of the Ethernet cables being utilized (e.g., the electrically conducting copper wires utilized in twisted pair Ethernet cabling is generally limited to transmitting up to 1 Gigabit per second (1 Gbps) of data.) As such, in one example, as the high definition video (and audio) streams transmitted by the PoE IP camera devices discussed above continue to require more and more data transmission bandwidth, the limitations of the Ethernet cables discussed above will eventually limit the ability to transmit their associated data at a bandwidth necessary to prevent the degradation of those high definition video (and audio) streams. Furthermore, Ethernet cables are also limited in the distances they can transmit data (e.g., the electrically conducting copper wires utilized in twisted pair Ethernet cabling are generally limited to transmitting data up to 100 meters), resulting in added expenses in situations when data must be transmitted at distances exceeding those capabilities.
Accordingly, it would be desirable to provide a single cable data/power transmission system that addresses the issues discussed above.
According to one embodiment, an Information Handling System (IHS) includes a chassis; a port connector that is located on the chassis; a cable coupling that is located on the chassis; a processing system that is coupled to the port connector and the cable coupling; and a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide an optical data and power transmission engine that is configured to: receive, via a powering device port that is included on a powering device and that is connected to the port connector, electrical signal data and power transmitted by the powering device; transmit, via an electrical wire coupling that is included in the cable coupling and to an electrical wire that is included in a cable and that is coupled to the electrical wire coupling in the cable coupling, the power; convert the electrical signal data to optical signal data; and transmit, via an optical wire coupling that is included in the cable coupling and to an optical wire that is included in the cable and that is coupled to the cable coupling, the optical signal data.
For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., personal digital assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, touchscreen and/or a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

As discussed below, the systems and methods of the present disclosure provide for data/power transmission in a single cable with higher data transmission speeds, longer cable lengths, reduced electrical component complexity in the cable (e.g., without the need for twisted pair electrical wiring and corresponding cable body shielding layers), and/or other benefits that will be apparent to one of skill in the art in possession of the present disclosure. In a specific example, conventional electrical wires such as twisted pair electrical wires are generally limited to 10 Gbps data transmission speeds, while optical wires such as fiber optic wires are expected to reach 100 Gbps data transmission speeds and beyond. Furthermore, cables including conventional electrical wires such as twisted pair electrical wires are generally limited to lengths of about 100 meters, which is much less than the cable lengths available via optical wires such as fiber optic wires (which are capable of transmitting data much further than electrical wires with the same data signal degredation), and the single cable optical data and power transmission system of the present disclosure is expected to increase cable lengths up to the limits of optical wire data transmission capabilities and electrical wire power transmission capabilities.
The method 600 begins at block 602 where a powering device transmits electrical signal data and power via a powering device port to a first transceiver device. With reference to

The method 600 then proceeds to block 606 where the first transceiver device converts the electrical signal data to optical signal data, and transmits the optical signal data to optical wire(s) in the cable. As illustrated in
The method 600 then proceeds to block 608 where the cable transmits the power via the electrical wire(s) to a second transceiver device, and transmits the optical signal data via the optical wire(s) to the second transceiver device. In an embodiment, at block 608, the cable 500 will operate to transmit the power 706 provided to the cable coupling 308 on the transceiver device 206a/300 via its electrical wires 506a, 506b, and up to 506c, and transmit the optical signal data 708 provided to the cable coupling 308 on the transceiver device 206a/300 via its optical wires 504a, 504b, and up to 504c.

As will be appreciated by one of skill in the art in possession of the present disclosure, the optical wires 504a-504c in the cable 500 that may include fiber optic wires that provide for the transmittal of optical signal data at multiples of the speed that electrical signal data is conventionally transmitted along with power over electrical wires such as twisted pair electrical wires, and those fiber optic wires are expected to reach data transmission speeds that are 10 times or more higher than available on conventional twisted pair electrical wires.
The method 600 then proceeds to block 610 where the second transceiver device converts the optical signal data to electrical signal data. In an embodiment, at block 610, the optical signal data and power transmitted via the cable 500 is provided to the transceiver device 206c/400. In some examples, with reference to the embodiment of the cable 500 illustrated in
However, in other examples, the cable 500 may be integrated with the transceiver device 206c/400 such that the electrical wires 412a-412c in the cable coupling 408 extend from the electrical wires 506a-506c in the cable 500 and, as such, the transmitting of the power via the electrical wires 506a/506c in the cable 500 operates to transmit that power via the electrical wires 412a-412c in the cable coupling 408.

Thus, systems and methods have been described that provide for the transmission of power on electrical wiring in a cable along with the transmission of data optically within that same cable. For example, a PoE powering device may transmit power and electrical signal data via one of its PoE powering device ports to a first transceiver. The first transceiver that is coupled to a cable may then transmit the received power via electrical wire(s) in the cable, while converting the electrical signal data to optical signal data, and transmitting the optical signal data via optical wire(s) in the cable. A second transceiver coupled to the cable and a PoE powered device port on a Poe powered device may then receive the power and the optical signal data transmitted via the cable, convert the optical signal data to electrical signal data, and provide the power and electrical signal data to a PoE powered device port on a PoE powered device. The PoE powered device may then utilize the power and electrical signal data. As such, PoE power and data transmission may be provided in a single cable with higher data transmission speeds, longer cable lengths, reduced electrical components complexity in the cable (e.g., without the need for twisted pair electrical wiring and corresponding cable body shielding layers), and/or other benefits that will be apparent to one of skill in the art in possession of the present disclosure.
