We've been down this road before when searching for a 1U 
Ethernet switch that provides decent fibre-only port 
density.

On the Cisco end, the 4928 is a little on the pricey side, 
and not very fetching if Layer 3 applications are needed, 
i.e., IPv6 is done in software, eek!

For these requirements, we keep coming back to Juniper's 
EX4200-24F, which is a 24-port fibre-only switch, with 4x 
1Gbps or 2x 10Gbps uplinks.

Brocade's NetIron CES/CER 2000 platforms are probably also 
worth considering, as they can scale to 24- and 48-port 
fibre-only densities. But they are fairly advanced, 
supporting a vast array of IP/MPLS features, so unless they 
have interesting licensing strategies, that proposition 
could be pricey.

Cheers,

Mark.
