Yep. There's plenty of fiber between the two buildings, so we may go that
route. Anyone know if there's any easy way to limit bandwidth on the
PA-POS-OC3 adapters?

Sounds like another job for rate limiting to me...

PA-POS-OC3MM $6000/card $38.71/Mbit
PA-FE-FX $3200/card $32.00/Mbit
PA-2FE-FX $5000/card $25.00/Mbit

Why muck with SONET unless necessary?

Yes.

Media converters are much cheaper than specialized FX cards like these. A
10Mbps converters are just $99 each and 100Mbps is $150.

Yes, but you need external power for these and they aren't
monitorable/configurable from any interface. Thus if one goes down
and you can't physically see it you have no idea where the problem
is until someone gets onsite.

Interestingly enough, sometimes it's cheaper to buy a small unmanaged switch with a fiber uplink port than to buy a
media converter...

And for the 7500s, you can get POSIP full cards for $250-$1000 depending
on fiber type, also from ebay.

Definitely more attractive than the work needed to prevent ground
loops when using copper.

I've seen PA-FE-FX for ~$200 on ebay recently, where did $3200 come from?
Also, I've seen the POSIP SM OC3 cards come up for fairly cheap too, so I
don't see why you'd want the multimode ones...

This is true of any physical fault, if your cable stops working you still have
to go and physically take a look...

But with something that is remotely monitorable (like a router)
and that is multiply connected the odds are alot higher that you
will be able to diagnose the problem. Also if the interface is
part of the router there is no extra cabling power needed. This
is a big plus IMHO.
