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.

What are the opinions/views on attenuating short, 1310nm LR cross-connects. Assume < 20m cable length and utilizing the same vendor optics on each side of the link. Considering the LR transmit spec doesn't exceed the receiver's high threshold value do you pad the receiver closer to the median RX range to avoid potential receiver burnout over time, or just leave it un-padded?
Thanks
