Abstract :
This letter verifies experimentally that gain tilt in amplified systems due to Raman crosstalk, when separated from gainshaping effects of the erbium-doped fiber amplifier (EDEA), accumulates as the sum of individual span contributions. This letter also demonstrates that a property of the EDFA, believed to be spectral hole burning, acts to level the gain tilt induced by Raman crosstalk.
