Pad 1310nm cross-connects?

Hi Chris,

I'm with an optics vendor, Luma optics. All our optics are field programmable to work in any intended network environment. Regarding your question, its  unnecessary to pad a 10km LR, even with such a short reach ( 20m) .  If it were an ER or ZR, it would be a different story. 
Good luck with you project.
