摘要
The output of the input polarisation divider (PBC) is connected through the fibre-optic telecommunications link (FOL) with the input of the optical coupler (S). The output of the optical coupler (S) is connected with the input of the output polarisation divider (PBS) by means of the HNLF type fiber-optic section (FO). The non-linear phenomenon of Raman diffusion is produced in the HNLF type fibre-optic section (FO). A pumping laser (LP) is connected to the section of coupling fibre-optic of the optical coupler (S) through a light signal polarisation analysis and modification system.
