The Higher Speed Ethernet Fabrics for MicroTCA.0 and AMC.2 committee is working to bring 40 GbE to these specifications. The specification currently runs at up to 10 GbE levels per 10GBASE-KX and 10GBASE-KR. There are several pieces involved in this effort, and careful attention has been made to its effect on related specifications.
The AdvancedMC (AMC) specifications were developed as a mezzanine approach to support AdvancedTCA (ATCA) systems. In the early days of ATCA, standardized AMC carriers were adopted to provide more modularity, scalability, and I/O options. With the pluggable AMCs on the carrier, a fixed ATCA board suddenly became very versatile. Later, these same AMCs were the core of the MicroTCA (mTCA) platform. So, it is perhaps not surprising that the architectures are continuing to converge in new ways to offer even more performance and flexibility.
