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
