ABSTRACT:
A method and an apparatus for optical transmission line power feed interference compensation for compensating for an electrical interference signal in a power feed conductor (12; 52) and in an associated second conductor (14; 54). The interference signal may be produced by electromagnetic induction or by local variation in earth potential. The compensation is performed by producing a variable compensation signal from an electrical interference signal produced in the second conductor and inputting the variable compensation signal onto the power feed conductor, in order substantially to compensate for or cancel the electrical interference signal produced in the power feed conductor.
