METHOD AND ARRANGEMENT FOR TRANSMITTING AN OPTICAL TRANSMISSION SIGNAL WITH REDUCED POLARISATION-DEPENDENT LOSS

摘要

The invention describes a method and an arrangement for transmitting an optical transmission signal (k(t); z (t) ) with reduced polarisation-dependent loss. A first transmission signal component (kx (t); Zu (t) ) and a second orthogonal transmission signal component (k? (t); zv (t)) of the optical transmission signal (k(t); z (t) ) are transmitted with a time difference (D) between said transmission signal components.
