摘要
A system for transmission over a repeaterless optical fiber line between an emitter and a receiver terminal, the system being of the type implementing remote optical amplification and local optical amplification on reception. The remote optical amplification consists in sending a pump beam from the receiver terminal towards at least one remote section of doped fiber situated upstream in said optical fiber line, said receiver terminal including, in particular, pumping means enabling said pump beam to be generated and enabling it to be injected into said optical fiber line. The terminal also includes means for performing said local optical amplification. According to the invention, said means for implementing local optical amplification are constituted by at least one local section of doped fiber situated within said receiver terminal between said pumping means and said optical fiber line.
