Let me clarify a bit-I understand that 40GBase-LR4 uses 4 10g wavelengths(lanes) which typically are: 1264.5- 1277.5 nm 1284.5–1297.5 nm 1304.5–1317.5 nm 1324.5–1337.5 nm My question is are there any vendors that make optics which 4 wavelengths(lanes) are something other than those typically used by 40GBase-LR4?
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). -- Brandon Martin
