It's a pretty normal situation. even with a 1-2m jumper I see light levels that are well below the maximum rx levels for 10km optics. e.g. the max might be .5 and the actual readings are -1.4 - -2.7. our WDM terminals sit in the the adjacent racks to the pop routers so they're all like that. ER/ZR is another matter. On Oct 19, 2013, at 7:33 PM, Chris Costa <ccosta92630 () gmail com> wrote:
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
