Key Points

Achieving a 512-Gbps data-rate signifies substantial performance in optical transmission over short distances, with low error rates.
The system operates below the HD-FEC threshold, ensuring reliable data integrity in high-density WDM settings.
Utilizing QPSK signaling enhances bandwidth efficiency by approximately 33%, optimizing transmission capacity and performance.
Short, 1-km distance with a self-homodyne configuration supports effective data center connectivity for high-speed applications.

Implication

Demonstration of high-density WDM 2-OTDM achieves 512-Gbps data-rate in optical links, indicating efficient transfer.

Abstract

Toward high-speed DSP-free optical link, we demonstrate a high-density WDM 2-OTDM self-homodyne transmission of 64-Gbaud QPSK signals over 1-km DSF, achieving 512-Gbps data-rate with a BER below HD-FEC threshold and a 33% improved bandwidth utilization.
