SYSTEMS AND METHODS TO REDUCE THE POWER CONSUMPTION OF AN OPTICAL FIBER AMPLIFIER (17710479)

Inventor Frédéric MAES

Brief explanation

The abstract describes a method for reducing the power consumption of an optical fiber amplifier. It involves filtering the optical output of one fiber to prevent a harmful portion from reaching another fiber, while allowing a portion that can contribute to the amplification of the second fiber to pass through. This allows for the reduction of power from an independent source. Each fiber in a sequence can provide pumping output to other fibers as long as the optical output is properly filtered. The sequence can be terminated with a low-pass filter to ensure the final output only contains the amplified signal without any other optical output.

Abstract

A method of reducing the power consumption of an optical fiber amplifier by which the optical output of a first optical fiber is filtered to prevent a detrimental portion of the optical output from reaching a second optical fiber, to transmit a signal for amplification, and to transmit a portion of the optical output that can contribute to optical pumping of the second optical fiber. By propagating an optical pumping portion output from the first optical fiber, as well as optical pumping from an independent source, the independent source's power level can be reduced. In a sequence of optical fibers, each fiber can provide some pumping output to one or more other fibers, as long as its optical output is properly filtered with appropriate optical components, such as a band-stop filter. A sequence can be terminated by a low-pass filter in order for a final output to contain the amplified signal free from any other optical output.

Inventor Yunbo Li

Brief explanation

This application describes a method and apparatus for transmitting protocol data units (PPDUs) in a communication system. The method involves sending a first data unit that includes a second data unit and a third data unit.
