    Raman Optical Amplifier ZRA1550

    Erbium-doped fiber amplifier (EDFA), due to spontaneous emission (ASE) noise and cascades, the accumulation of spontaneous emission noise, will greatly reduce the SNR of system receiver, thus limits the system capacity and non-relay distance. The new generation of Raman fiber amplifier (ZRA1550) achieves the amplification of the optical signal by the optical gain generated by the Stimulated Raman scattering (SRS). FRA has a wide gain spectrum; the gain bandwidth can be further broadened by th...
