The MRMAC subsystem is a highly flexible, IEEE-compliant network interface for applications that require a very high bit rate, such as:
  • Ethernet switches
  • IP routers
  • Data center switches
  • Communications equipment
The capability to interconnect devices at 10, 25, 40, 50, and 100 Gb/s Ethernet rates becomes especially relevant for next-generation data center networks where:
  • To keep up with increasing CPU and storage bandwidth, rack or blade servers must support aggregate throughputs faster than 10 Gb/s (single lane) or 20 Gb/s (dual lane) from their Network Interface Card or LAN-on-Motherboard (LOM) networking ports.
  • Given the increased bandwidth to endpoints, uplinks from Top-of-Rack (TOR) or Blade switches need to transition from 40 Gb/s (four lanes) to 100 Gb/s (four lanes) while ideally maintaining the same per-lane breakout capability.
  • Due to the expected adoption of 100GBASE-CR4/KR4/SR4/LR4, SerDes and cabling technologies are already being developed and deployed to support 25 Gb/s per physical lane, twinax cable, or fiber.
