ABSTRACT:
In a method of transmitting an electromagnetic signal in an optical fiber a polarized optical base signal is generated and input at a first and of an optical fiber, an optical signal emerging from the fiber after the base signal has passed through it is recovered at a second end of the fiber; this emergent signal is processed by electro-optical modulation with the electromagnetic signal which is to be transmitted and polarization conversion is effected, and the optical signal modified in this way is reinput to the said second end of the fiber; an optical return signal emerging from the fiber after the modified optical signal has passed through it is recovered at the first end of the optical fiber and this is analyzed in order to determine the characteristics of the electromagnetic signal.
