I also quite like the bolded comment below. Isn't that the same timeline that POET are looking to demonstarte their complete tranciever? I know its complete speculation, but it does make some sense. At least to my untrained eye it does. We have afterall had a working relationship with IBM

IBM's current prototype runs at a wavelength of 850 nanometers, which is the standard wavelength for VCSEL-based multi-mode optical links, making it suitable for processor-to-memory, processor-to-processor and server-to-server communications. Once the complete transceiver is demonstrated later this year or early 2018, the price crossover point will have been reached, according to Thomas Toifl, manager of the high-speed Interconnects group at IBM Research in Zurich.
