• Backplane and switch fabric speeds are growing faster than I/O speeds

• Fewer interfaces and cables to manage even if we can make them smaller

• Avoid multi-chassis platform implementations

• Improve scalability within a product family

CDFP MSA Addresses 1st Gen. 400G Short Reach

§  First product will be active optical cables (AOC) and copper cables

§  Transceivers will follow §  Leverage 4x CAUI-4 25Gb/s

electrical channel §  Leverage 25Gb/s optics §  Quick to market, leverages what

is available §  32mm pitch allows >10/linecard

9 © 2013 Ethernet Alliance

Longer Reaches §  Leverage 25Gb/s electrical channels with

higher order modulation signaling §  Utilize CWDM to serve the industry with SM

duplex fiber

§  2nd generation uses 50G electrical channel
