The present disclosure relates in general to information handling systems, and more particularly to systems and methods for providing a hybrid optical and electrical port to legacy electrical port converter.
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.
An information handling system may have a network interface or other input/output (I/O) interface having a hybrid optical/electrical port, including an optical interface for communication of data via a hybrid cable and an electrical interface for delivery of electrical energy via the hybrid cable. Accordingly, a device coupled to the hybrid optical/electrical port via the cable may be powered from the hybrid optical/electrical port. For example, Power-over-Ethernet may be implemented in such a manner.
While connectivity of hybrid optical/electrical ports to next-generation Power-over-Ethernet powered devices may be possible as such devices may be manufactured with integrated optical ports and electrical power pins, existing legacy devices having only electrical interfaces (e.g., devices having RJ-45 connectors) may not be supported by the hybrid optical/electrical ports.
In accordance with the teachings of the present disclosure, the disadvantages and problems associated with coupling legacy electrical port devices to hybrid optical/electrical ports may be reduced or eliminated.
In accordance with embodiments of the present disclosure, a hybrid optical/electrical port to electrical port converter may include a hybrid optical/electrical connector, an electrical connector, and a circuit electrically and communicatively coupled between the hybrid optical/electrical connector and the electrical connector. The circuit may include a power mapping module interfaced between the hybrid optical/electrical connector and the electrical connector and configured to map electrical power rails from electrically-conductive conduits of the hybrid optical/electrical connector to electrically-conductive conduits of the electrical connector, such that a device coupled to the electrical connector can be powered from a cable coupled to the hybrid optical/electrical connector and an integrated transceiver module interfaced between the hybrid optical/electrical connector and the electrical connector. The integrated transceiver module may be configured to convert optical signals received by optical transmission media of the hybrid optical/electrical connector and convert such optical signals into equivalent electrical signals and drive such equivalent electrical signals to electrically-conductive conduits of the electrical connector and convert electrical signals received by electrically-conductive conduits of the electrical connector and convert such electrical signals into equivalent optical signals and drive such equivalent optical signals to the optical transmission media of the hybrid optical/electrical connector, such that the device can communicate with a hybrid optical/electrical port of an information handling system via the cable.
In accordance with embodiments of the present disclosure, a method for fabricating a hybrid optical/electrical port to electrical port converter may include electrically and communicatively coupling a circuit between a hybrid optical/electrical connector and an electrical connector, wherein the circuit comprises a power mapping module interfaced between the hybrid optical/electrical connector and the electrical connector and configured to map electrical power rails from electrically-conductive conduits of the hybrid optical/electrical connector to electrically-conductive conduits of the electrical connector, such that a device coupled to the electrical connector can be powered from a cable coupled to the hybrid optical/electrical connector and an integrated transceiver module interfaced between the hybrid optical/electrical connector and the electrical connector. The integrated transceiver module may be configured to convert optical signals received by optical transmission media of the hybrid optical/electrical connector and convert such optical signals into equivalent electrical signals and drive such equivalent electrical signals to electrically-conductive conduits of the electrical connector and convert electrical signals received by electrically-conductive conduits of the electrical connector and convert such electrical signals into equivalent optical signals and drive such equivalent optical signals to the optical transmission media of the hybrid optical/electrical connector, such that the device can communicate with a hybrid optical/electrical port of an information handling system via the cable.
