Did 40GBASE-FR ever catch on?  It was supposed to be single-lane serial 
40Gbps on 1310nm with the receiver also accepting 1550nm.

For that matter, what are all the optical transport folks using for 
~40Gbps OTU3?  Or did they all just skip that and go straight to 
~100Gbps OTU4 on coherent optics (which are fairly readily available 
albeit in CFP, not QSFP).
