ABSTRACT:
A laser beam conducted through an optical fiber cable is phase modulated communication purposes by a signal encoder operative through a source of current to generate a modulated magnetic field applied to a magnetrostrictive sheathing. The magnetostrictive sheathing is annealed and covers a portion of the fiber cable which undergoes dimensional change to effect modulation.
