METHOD AND APPARATUS FOR PERFORMING ELECTRODING IN AN UNDERSEA OPTICAL TRANSMISSION SYSTEM EMPLOYING SMALL FORM FACTOR REPEATERS
摘要
A method and apparatus is provided for applying an electroding tone to a power conductor located in an undersea optical cable employed in an undersea optical transmission system having at least one repeater. The method begins by applying a DC line current to the power conductor. The DC line current has a value sufficient to power the repeater and less than a value sufficient to power the repeater and to perform electroding. An AC current is impressed on the DC line current at a prescribed frequency and a peak-to-peak amplitude ranging from zero and a prescribed value to generate the tone. The impression or application of the AC current is terminated after a period of time at least sufficient to locate the optical cable or an optical cable fault.
