Sorry guys I have been tied up and have not been following the forum like I normally do.

My reference was intended to be "transponder" as follows:

Poet's optical interposer has applications in a wide range of high-growth markets, primary among them being high-performance computing, networking, optical transceivers, and transponders and automotive LIDAR systems. This platform technology is applicable to both gallium-arsenide- (GaAs) and indium-phosphide-based optical components. Optical engines for single mode transceiver modules represent the initial high-volume application for Poet's optical interposers.

Transponders associated with satellite com is a growth market forecasted to be worth $20 billion by 2020 (from memory). It was the first time I have heard them mention transponder as an application for the POET dielectric platform. High performance computing I expected to see on that list but was not familiar with what the market is for the transponder. My initial thoughts were associated with connected vehicles.
