Applicability of Large Effective Area PCF to DRA Transmission

抄録

We describe the applicability of photonic crystal fiber (PCF) with an enlarged effective area A_eff to a distributed Raman amplification (DRA) transmission. We investigate the DRA transmission performance numerically over a large A_eff PCF taking account of the signal-to-noise ratio (SNR) improvement R_SNR in the S, C, and L bands. We show that an R_SNR of 3dB can be expected by utilizing DRA with a maximum pump power of 500mW when the A_eff of the PCF is 230µm².
