All, There was an issue on Friday with a server, but it was not
clear that messages were not being forwarded to the HSSG reflector. I received
an inquiry regarding this from Dave Martin of Nortel this morning. I am
attaching his email that was not forwarded. If you sent a message that you did not see forwarded to the
reflector, please re-send today. John From: Martin, David
(CAR:Q840) During the discussion on Reach Objectives there didn’t
appear to be any mention of corresponding BER. Recall the comments from the floor during the July meeting
CFI, regarding how 10GigE has been used more as infrastructure rather than as
typical end user NICs. And that the application expectation for 100GigE would
be similar. Based on that view, I’d suggest a BER design target of
(at least) 1E-15. That has been the defacto expectation from most carriers
since the introduction of OC-192 systems. The need for strong FEC (e.g., G.709 RS), lighter FEC (e.g.,
BCH-3), or none at all would then depend on various factors, like the optical
technology chosen for each of the target link lengths. ...Dave David
