[2] A data pulse sequence follows a nonreturn-to-zero (NRZ) coding format when temporal duration of the pulses is fixed to coincide with the inter-symbol period, so that there are no guard times between consecutive symbols. When the pulse duration is shorter than the inter-symbol period, the sequence follows a return-to-zero (RZ) coding format, leaving guard times between consecutive symbols.

[31] Before each electro-optical modulator, a tunable optical delay line and a polarization controller are connected in order to align the voltage drive to the optical signal and to maximize the modulation efficiency. Additionally, RF amplifiers were used to boost the voltage drive signals of each electro-optical modulator.
