Background(toberemovedforactualCFI)• Itisexpectedthat,ifsuccessful,thisCFIwillexpandthescopeofthecurrent“Beyond10k”StudyGroup(http://www.ieee802.org/3/B10K/index.html)
• AstrawpollormotionwillberequestedintheB10kstudygroupinNovembertoassesssupportfromthoseparticipantstoaccepttheincreasedscopeiftheCFIissuccessful.
• Untilthen,wecanonlystatewearerequestinganewStudyGroup• Weanticipatethatthiswouldresultinanexpandedscopeof:“Beyond10kmOpticalPHYsfor50Gb/s,100Gb/s,200Gb/s,and400Gb/sEthernet”
• ThisCFIisfocusedonly ontheinclusionoftheadditionaldatarateintotheB10kdiscussions
• Thereforetechnologyfeasibilityisdiscussed,buttechnologychoicesandtrade-offsremainthedomainoftheStudyGroup,nottheCFI
