CSRZ-ASK and DPSK 40 Gb/s All-Raman WDM Transmission Based on UltraWave Fiber
In this paper, we report a complete experimental and numerical analysis of 40 Gb/s WDM ultra long-haul (ULH) transmission using CSRZ-DPSK and CSRZ-ASK modulation formats on UltraWavetrade fiber spans. Experimental results compare well with full numerical simulations
Performance Comparison of SSMF and UltraWave Fibers for Ultra-Long-Haul 40-Gb/s WDM Transmission
International audience; We experimentally compare the performance of standard single-mode fiber (SSMF) and UltraWave fiber (UWF) for ultra-long-haul (ULH) 40-Gb/s wavelength-division-multiplexing transmissions. We used the carrier-suppressed return-to-zero amplitude-shift-keying (CSRZ-ASK) and the carrier-suppressed return-to-zero differential-phase-shift-keying (CSRZ-DPSK) formats, which are particularly well-adapted to 40-Gb/s pulse-overlapped propagation. We demonstrate that transmission distance well beyond 2000 km can be reached on UWF with both the CSRZ-ASK and CSRZ-DPSK formats, or on SSMF with the CSRZ-DPSK format only, thus indicating that SSMF-based infrastructure of incumbent car…
