A coherent optical-fibre communications system using polarisation modulation. |
| 摘要 |
<p>A coherent optical communications system using polarisation modulation, wherein the polarisation modulation of the optical signals is obtained by using two lasers (1, 2) emitting orthogonally polarised radiations at different frequencies, which are combined without losses prior to transmission over the line. <IMAGE></p> |
