I am curious how much of a performance gap exists between new long haul fib=
er and fiber laid during the Great Boom from 1998-2001. We are very close t=
o 20 years.
I assume there are two dimensions, namely bit carrying capacity of an indiv=
idual wave and total bandwidth capacity of a fiber pair. I have been told a=
nd readily believe that fiber improvements do make a difference. But I have=
no sense of magnitudes. My impression is that the 1998-2001 fiber probably=
cannot handle above 100 gig waves and about 14 terabits per fiber pair at =
least on Trans-Atlantic cables.
