Repeater less fibre optic transmission system having transmitted information amplitude modulation and polarisation phase diversity applied reducing Brillouin effect and allowing increased transmission levels.

摘要

the repeater less fibre optic transmission system has transmitted information bits which are modulated in amplitude and at the same time have an applied random phase diversity. The technique allows the Brillouin effect to be reduced, so that the reflected power level along the line is reduced for a given injected power level.
