We have obtained 60 dB of internal (on-off) gain with a continuous-wave (CW) fiber optical parametric amplifier (OPA), by using an isolator between two fiber segments to increase the pump stimulated Brillouin scattering (SBS) threshold. Sub-dB penalties were measured for transmission of 10Gb/s signals, with 35dB of gain.
