They're fine to run back to back..

 

Average launch power                                  -8.2 through 0.5 dBm

Average receive power                                 -14.4 through 0.5  dBm

Receiver saturation                                         0.5 dBm

You'll never launch hotter than the max RX..

 

 

They usually launch @ -2 -> -3dbm..

Hi folks.



These are "10KM" optics - how short of a run can you use them for?  We have
several of these spared at the moment and I'd like to use them for
connections between MX480's in the same rack. will they run too hot?



The specs on the Juniper site show:
