Method for Providing Power to Fiber Optics Devices

In a number of system applications, it is desirable to be able to connect both copper and active fiber optic (FO) cables (cables with the optical module in the cable backshell) to a common card port. The copper cables provide the most cost-effective solution, but they are limited in length due to SI. The FO cables are more expensive, but provide a significant improvement in cable length. The most cost-effective solution for the customer is to provide both short copper cables and long FO cables to the customer. In many of these applications, the power required to power the FO module in the active FO cables is not available on one of the cards being connected. An example of this is found with the SAS cards. The 3 Gb mini-SAS cards do not provide power to the cable port. The 6 Gb HD SAS cards provide the power required. Because there is no power available on the 3 Gb card, this connection is limited to copper cables. This disclosure describes a method to provide the power required for the active FO modules on both ends of the cable from one of the cards on one end of the cable.

    The current solution involves using a photovoltaic cell to convert light into electrical power. The main drawback of this solution is the amount of electrical power that can be delivered, which is in the range of 0.05 w to 0.1 W. [1,2]

    This invention describes a method of providing power to both ends of the cable by coating the outside of th...
