a Example images of the letters and clothes and the recovered images. b Average fidelities when using different MMF lengths in the system. Collected time signals when the MMF length is c 1000 m and d 400 m respectively. The period of the laser pulses is 65 ns, corresponding to a repetition rate of 15.4 MHz. The width of the waveforms is 18.7 ns, which allows the repetition rate to be further increased to 53.5 MHz.
