Coherent 1-μm-Band Co-Transmission with C+L-Band Channels over 50-km Hollow-Core Fiber
We experimentally demonstrate simultaneous coherent transmission across 1-$μ$m and C+L bands, carrying $54\times125$-GBaud PDM-16QAM C+L channels and $2\times15$-GBaud PDM-QPSK 1-$μ$m channels over 50 km, highlighting 1 $μ$m as a promising additional transmission window while avoiding gas-absorption constraints in C/L-band of HCFs.
