Microsoft to Commercialize MicroLED Datacenter Cables by Late 2027 and Expand Hollow Core Fiber Deployment
Microsoft is set to commercialize its MicroLED-based optical cable system, known as MOSAIC, by late 2027, developed with MediaTek and other partners. This technology replaces lasers with inexpensive MicroLEDs, achieving roughly 50% lower energy consumption compared to conventional optical cables and supporting thousands of parallel data channels.
The system has been miniaturized into a standard transceiver compatible with existing datacenter equipment. Microsoft is also expanding its Hollow Core Fiber (HCF) technology, which offers up to 47% faster data transmission and approximately 33% lower latency than traditional fibers.
HCF is already in use in some Azure regions, supporting longer-distance connectivity between data centers. The combination of these technologies aims to improve energy efficiency and scalability in response to increasing AI workloads.
