BroadMarketPotentialforMMFDuplex

• Until 40GbE, all multimode Ethernet modules were duplex

• SR4 configuration helped launch the 40GbE market

• Duplex MMF still a desired solution, quickly reaching 38% of the 40GbE MMF market in 2017

BroadMarketPotentialforMMFDuplex

At 100GbE:

• SR4 configuration again helped launch the market

- SR10 never widely deployed

• Duplex MMF still a desired solution

- Projecting a 27% share of the 100GbE MMF market by 2022

• Large Enterprise L-S switch links migrating from 10G Duplex (port groups)

• MMF cabling infrastructure can serve at least three generations using 1-pair connectivity

• Server speeds will increase in the shorter term, 200G will help maintain contention ratios

• Continuing 1-pair infrastructure lowers the cost of upgrade – stated preference of several Enterprise operators
