Path to optical links still dark
February 21, 2012 // Rick Merritt
Experts agree printed circuit boards and processors will eventually need optical interconnects. But just when and how the industry will get there is still unclear.
A byte-per-flop gap is opening up thats a major limit on architectures that gets worse and worse as we head to 2020 and beyond, said David Miller, an optical research lab at Stanford, speaking in an evening panel at the International Solid-State Circuits Conference.
We are getting close to the point where optical is more attractive, said John Stonick, a Synopsys scientist and chair of the panel. But optical interconnects have always been the next thing, and the big questions are when and how we get there, he said.
Keishi Ohashi, an optical expert from NEC Corp., said optical may follow a path like hard disk technologies. It took nearly twenty years for powerful magneto-resistive heads to emerge from their beginnings in labor-intensive magnetic coils, he said.
Bert Offrein, an optical expert with IBM Research, noted milestones and challenges IBM has seen. In 2008, the company built Roadrunner, the first petaflop computer, using optical interconnects to each server board.
Last year IBM created its Power P775 high-end server that brought optical links to the processor. It fused 56 fibre cables to modules with 56 transceivers integrated with help from Avago on to each IBM CPU.
It required 100 additional assembly steps to bring the optics to the chips in addition to building transceivers themselves, said Offrein. Thats justified for some high-performance systems, but for general servers we need something easier, he said.All news
