| 摘要 |
An apparatus for transmitting optical signals between a central unit (1) and at least one remote unit (2), said central unit comprising - at least one amplified spontaneous emission source (11, 110) of an optical signal, first means (17, 170) 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 (24) 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 (17). |
