On the Feasibility of SCL-Band Transmission over G.654.E-Compliant Long-Haul Fibre Links

Published 29 Jul 2025 in physics.optics, cs.SY, and eess.SY | (2507.21865v1)

Abstract: We demonstrate the first SCL-band long-haul transmission using G.654.E-compliant fibre, achieving 100.8 Tb/s (GMI) over 1552 km, despite its 1520 nm cutoff wavelength. Due to the fibre's ultra-low loss and low nonlinearity, the achievable-information-rate with lumped amplification is comparable to that of G.652.D-compliant fibre links with distributed-Raman-amplification.
