re: Infinera Marks PIC Hours By my calculations, Infinera's reliability sample size is 114 PICs (1,000,000 hours / (24*365)).

Is this sufficient to tout ones reliability?

After 5 years and $250M in funding, this does not sound impressive.

Where are the Tier 1 wins? That would be news.

re: Infinera Marks PIC Hours It is easy to take potshots at the accomplishment but if you can do it better let us all know about that. Getting long term stability for compound semiconductors working at these speeds is not a trivial task - go try it for yourself.
And don't be shocked when the equivalent of a CRS-1 appears in a cigar box package. The problem there is that the investment required will be billions - and at what return on investment ?

re: Infinera Marks PIC Hours Gad:

Try 10000 EDFAs for a year; thats about two orders of magnitude better...and still not good enough.

Is Dave throwing some of his own $ in yet? When you see that, then you can plan your exit party, not a nanosecond before.

re: Infinera Marks PIC Hours The Press Release said "The PICs' record of reliability, stretching over a year of operations at hundreds of customer sites on three continents"

Hundreds of sites, but only 1M hours? Does that mean <1 PIC/Site?

Lets say that by 100's they meant 200. You would at least expect 40 wavelengths, so there would be a minimum of 4/site or 800 parts for 7.2M hours....unless their marketing guys can't do arithmetic

re: Infinera Marks PIC Hours Yep, 119 parts won't even make the grade (125 parts minimum) to allow a 3000 hour Damp Heat GR-468 qualification.

Obviously these parts are as rare as sanity in the funding decisions by their VCs
