The components going into ethernet devices are cheaper because of high 
volume, but it's also that the SONET/SDH stuff is grossly overpriced 
"because we can" by short sighted vendors. There are cheap ethernet ports 
for cheap platforms, there are basically no cheap SONET/SDH ports 
anywhere.

POS is technically better compared to Ethernet for carrier links imho, but 
for instance Cisco price their SPA-TENGE-XFP at 1/6 the cost of 
SPA-OC192-XFP.

I know quite a lot of people who would gladly pay more for POS, but not 
that much more.
