An optical amplitude modulator for modulating signals for transmission by a fiber optic link. The modulator comprises of a plurality of optical transmitters, whereby each transmitter is driven by an electronic circuit. Generally, each optical transmitter provides a light output, and the light outputs of the plurality of optical transmitters are combined optically for transmission as an optical output signal. Additionally, each of the plurality of optical transmitters has an associated optical filter, whereby each filter has a different level of opaqueness. Each filter, filters light output from the associated optical transmitter.
