Abstract
An apparatus for transmitting optical signals between a central unit () and at least one remote unit (), said central unit comprising—at least one amplified spontaneous emission source () of an optical signal, first means () adapted to polarize the optical signal deriving from the amplified spontaneous emission source in a first polarization plane by forming a first polarized optical signal (POS). The apparatus comprises second means () configured to receive said first polarized optical signal and to polarize it in a second polarization plane, orthogonal to the first plane, by forming in said first means a second optical signal (SOS) which is orthogonally polarized with respect to the first optical signal ().
