Tim Yes we have built several links with the 1310nm devices on Corning LEAF. One span distance was 14 KM. Can we offer you a quote on optics and installation support? Thanks, Kevin L.

Anyone run 1000BASE-LX/10GBASE-LR 1310nm optics over a ~10km Corning LEAF G.655 span? I understand this fiber is not optimized for such usage, but what is the real-world behaviour? I'm having a hard time finding hard data. (Normal optics will be 1550nm and DWDM over ~40-100km spans.) -- Tim:> ----- No virus found in this message.
