We also realize wavelength remodulation for carrying upstream on-offkeying (OOK) data to reduce the cost budget at the optical network unit.
为了降低光网络单元的成本预算，我们对下行的光载波进行了上行传输开关键控信号的重调制。

A scheme to achieve ultrahigh speed all-optical format conversion from on-offkeying (OOK) to phase-shift keying (PSK) by using the linear filtering in the silicon ring resonators is proposed.
The ultra wideband (UWB) radio models have been introduced with pulse-position-modulation (PPM), on-off-keying (OOK) and pulse-amplitude-modulation (PAM).
