The ability downside, Microsoft argues, begins with the cables themselves.
How MOSAIC works
Copper interconnects high out at roughly two meters at excessive knowledge charges, limiting them to inside a single rack. Laser-based fiber optic cables go additional however devour extra energy and are delicate to temperature and mud, Microsoft stated within the put up. MOSAIC reaches as much as 50 meters whereas drawing much less energy than both, the corporate added.
“Imaging fiber seems to be like a regular fiber, however inside it has hundreds of cores,” Paolo Costa, a Microsoft associate analysis supervisor and the venture’s lead researcher, wrote within the put up. “That was the lacking piece. We lastly had a solution to carry hundreds of parallel channels in a single cable.”
MOSAIC shouldn’t be Microsoft’s solely optical networking guess, and it isn’t the one furthest alongside.
HCF is already in manufacturing throughout Azure areas
MOSAIC arrives alongside Hole Core Fiber (HCF), a complementary expertise Microsoft is already deploying globally. HCF carries optical alerts by means of air relatively than glass, delivering as much as 47% sooner knowledge transmission and 33% decrease latency than standard single-mode fiber, in line with revealed analysis from the College of Southampton cited by Microsoft.
Frank Rey, Microsoft’s normal supervisor of Azure Hyperscale Networking, stated within the put up that the 2 applied sciences are complementary — HCF for long-distance inter-datacenter hyperlinks, MOSAIC for in-facility GPU and server connectivity.
