Dear Mr. Carpenter,
Juniper is expensive. If you buy a new 48 x 10GbE/SFP+ fiberswitch from an H3C
based vendor like Huawei, you get the whole unit for $10,000. All you need in
addition to that are the lasers and these will set you back a hundred bucks per
port in case you select 1310nm SFP+

Note that this requirement is implemented in the driver. YMMV depending
on OS, but in Linux you can disable it with

EX4200s are abundant for much less in Ebay (for the 24port 1g requirement).
In the 10G space though, indeed, Juniper is expensive.

I just purchased some empty Intel X520-DA2 cards and then picked up the
E10GSFPSR-compatible optics for them from Fiberstore.

I never saw many cheap 48port 1U sfp switches as people bought copper
at that speed so the ones that were around were relatively expensive.

I wouldn't say that used or grey market really count as viable options. If we
count that, I can get 1GbE for free.
The reality is that for a unit that is supported (both software releases and
warranty) properly for deployment in mission critical situations, 10GbE costs
~10x 1GbE.
While the
Um. You don't have an option for old copper plants. This stuff gives you
2.5gig or 5gig on cat5/cat5e (depending on distance).
If you can do 10g you really shouldn't be carrying about this stuff. In the
optical world just jump to using 10Gig (where you can)

Why wouldn't you go straight to 10G ?

I've a couple 10 port Cisco switches that support 2.5 and 5gbps over cat5e,
just wondering if there are any other vendors out there with offerings that
support these newer ethernet speeds. Supporting cat5e for these multi-gig
speeds is a real boon in many circumstances given the wide popularity
