Novel tools and techniques are provided for implementing data transmission, and, more particularly, to methods, systems, and apparatuses for implementing data transmission utilizing techniques used for transient state computing with optics. In various embodiments, a photo-transmitter system of a chromatic transient state data transmission system might send, over optical transmission media, a data signal comprising a series of chromabit values, by emitting, using a set of colored light emitters, a combination of colors representing each chromabit value. A photo-receiver system of the chromatic transient state data transmission system that is communicatively coupled to the photo-transmitter system via the optical transmission media might receive the data signal, each distinguishable color as detected by each photoreceptor corresponding to a combination of emitted colors. A computing system might autonomously convert the data signal comprising the series of chromabit values into a converted data signal that is compatible with a receiving device.
