Abstract: The method of transmitting data includes encoding, at an optical line terminal, data to be transmitted over a plurality of wavelength channels; providing the encoded data to corresponding lasers as modulation inputs, to enable the lasers to generate optical signals representing the data; multiplexing the optical signals; and equalizing the multiplexed optical signals for transmission via an optical transmission link. The method of receiving data includes de-multiplexing, at an optical network unit, optical signals received from an optical transmission link; selecting, from the de-multiplexed optical signals, an optical signal corresponding to a particular wavelength channel; converting the selected optical signal into electric signals; and decoding the electric signal to determine the data.

Abstract: Radio controlled cartridge ammunition (20; 30) for a weapon (26), wherein the ammunition comprises control circuitry (21) adapted to enable and/or disable a mechanism for the ignition of the propellant charge (32) of the ammunition (20; 30) in response to a wireless radio control signal. Thereby the control circuitry (21) extracts, from the wireless radio control signal received at the ammunition's geographical location, information indicative of said geographical location, and compares the extracted information with information indicative of a geographical area where the ammunition (20; 30) is allowed to be fired off the weapon (26). Hence, the ignition mechanism is controlled based on the result of the comparison.
