10.92-Tb/s (273/spl times/40-Gb/s) triple-band/ultra-dense WDM optical-repeatered transmission experiment

With LD-pumped gain-shifted thulium-doped fiber amplifiers, polarization interleave multiplexing combined with wavelength/polarization demultiplexing for 50-GHz-spaced 40-Gb/s/ch WDM signals, and a transmission line optimization for triple-band systems, the first 10-Tb/s WDM transmission in single fiber using S-, C- and L-bands is demonstrated.
