OFC 2014 industry reflections - Part 1

Gazettabyte is asking industry figures for their thoughts following the recent OFC 2014 exhibition and conference: the noteworthy developments and trends, what they learnt at the show, and the topics to track in the coming year.

The CFP2 form factor pluggable - analogue coherent optics (CFP2-ACO) at 100 and 200 Gig will become the main choice for metro core networks in the near future. 

I learnt that the discrete multitone (DMT) modulation format seems the right choice for a low-cost, single-wavelength direct-detection 100 Gigabit Ethernet (GbE)  interface for data ports, and a 4xDMT for 400GbE ports.
