After more than a decade of research, Intel's new connector that uses light as a speedy way to shuffle data between computers is finally ready to replace slower copper cables. The MXC optical cables will be first implemented at the rack level and use light and lasers to move data between servers, storage, networking, and other computing resources. The cables will transfer data at speeds of up to 1.6Tbps (bits per second), outpacing the throughput on copper cables used for networking in data centers.
