10 Spatial mode transmission over low differential mode group delay fibre employing all-fibre photonic lanterns

摘要

Wavelength and mode-division multiplexed 4.45 km low-DMGD (0.05ns/km) 6-LP mode fibre transmission employing low-loss all-fibre 10-port photonic lanterns is demonstrated using a 20×20 multiple input multiple-output time-domain equalizer. We measured an MDL of 8.7± 1.7dB over 10 hours.
