An optical signal production and modulation system that enables a multiplexed optical signal to be created for transmission without the use of more traditional laser-based optical transceivers. The system includes a light source library and a plurality of modulating optical transceivers. The light source library receives a composite wavelength un-modulated light signal, amplifies it, and separates it into discrete signal channels. Each of these channels is sent to a modulating optical transceiver, which employs a combination of lenses, reflective components, and a pin diode to modulate the channel with the desired data to be carried. The modulated channel can then be forwarded for multiplexing and transmission via a communications network.
