• 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

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
