Wideband Inline-Amplified WDM Transmission using PPLN-Based OPA with Over-10-THz Bandwidth

We demonstrate the first inline-amplified transmission with PPLN-based polarization-independent OPA offering 5.125-THz amplification bandwidth and >15-dB gain using 800-Gb/s PDM PS-36QAM signals. Results indicate the OPA potentially extends the WDM bandwidth to over 10.25 THz.
