[802.3_NGEPON] 40Gb/s Serial Interface defined by 802.3bg

Hi Duane,
I relayed your concern to Ed Harstead on whether a 40 Gb/s serial interface had been defined yet in 802.3, after discussion on Eugene's NGEPON contribution yesterday

that included Ed's Ethernet serial data rate evolution graph.

Ed pointed out that he believed this interface was defined in the 802.3bg standard (40GBASE-FR) in 2011 as follows:

40 Gb/s serial SMF PHY (40GBASE-FR) is specified in IEEE Std 802.3bg™-2011 (Amendment to IEEE Std 802.3™-2008), Amendment 6: Physical Layer
and Management Parameters for Serial 40 Gb/s Ethernet Operation Over Single-Mode Fiber

I looked at the standard  briefly, and found this entry in Table 80-1:

40GBASE-FR 40 Gb/s PHY using 40GBASE-R encoding over one lane on single-mode
fiber, with reach up to at least 2 km (see Clause 89)
