The predicted relative intensity noise (RIN) transfer function for distributed amplification based on centrally-pumped random distributed feedback ultralong Raman fiber lasers (RDFLs) is found and studied over a broad range of possible lengths and signal powers, showing that the values of the RIN transfer function and the RIN cut-off frequencies are dependent upon both parameters. RIN transfer is shown to be generally higher than in a typical ultralong cavity Raman fiber laser (URFL) pumped from the extremes.
