RE: PAM-5, what are your BERs ?



Title: RE: PAM-5, what are your BERs ?
Dave:
 
Are you suggesting, that if the BER of GbE is 10^-12, then the BER of the 10xGbE should be less?  For example, 10^-13 to maintain the expected throughput gain from 10xGbE?

Jaime,

A clarification on backbone transport BER spec's. For OC-48 systems, although BCR GR-253 spec'd
1E-10 for worst case end-of-life, the defacto customer requirement was 1E-12. Similarly, for OC-192
systems, although BCR GR-1377 spec'd 1E-12 for worst case end-of-life, the defacto customer
requirement has been 1E-15. Note that the current target proposed for the ITU defined Optical
Transport Network is also 1E-15.
