Parallel optics provides multiple high bandwidth interconnects in a space ten time smaller than co-axial copper interconnects. With almost unlimited bandwidth it is clear that all future interconnects for embedded systems will use parallel optics. Reflex Photonics supplies chip size rugged parallel optics transceivers to operate in harsh military e. Command, control, compute, communicate, intelligence, surveillance, and reconnaissance systems (C4ISR) rely on accurate views of local situations for decisions that are critical to national defense. Fiber optics interconnect has emerged as the only viable technology to carry the massive amount of information generated by high resolution radars, inf. Illustration of the relation between the different elements of C4ISR systems (Command, Control, Compute, Communicate, Intelligence, Surveillance, Reconnaissance).Intelligence, surveillance, and reconnaissance (ISR) trend is for more information and accurate views of the situations with longer mission times. For example, UAVs with high resolution sensors and high performance embedded computing have become an invaluable tool to defense. They can survey large areas quickly and at much lower cost than manned ai. System performance of an optical link is determined by the quality of the signal generated by the TX, lane impairments (fiber optics cable and interconnects) and the sensitivity of the receiver over a bandwidth range. Rugged transceivers must operate over wide temperatures (at least -40 ºC to 85 ºC) which makes it challenging to maintain low bit er.
