Re: PCIe adapters supporting long distance 10GB fiber?

Hi,

most 10GE cards have either direct 10GBASE-T port(s)s or SFP+ slot(s).

The SFP+ transceiver you plug in determines the range. (SMF/MMF,
wavelength, link budget)
Reading the optical parameters is a bit tricky on most NICs.

Hello,

We are deploying more and more server based routers (based on BSD). We have
now come to the point where we need to have 10GB uplinks one these devices
and I prefer to plug in a long range 10GB fiber straight into the server
without it going first into a router/switch from vendor x. It seems to me
that all the 10GB PCIe cards only support either copper 10GBASE-T, short
range 10GBASE-SR or the 10 Km 10GBASE-LR (but only very few). Are there any
PCIe cards that support 10GBASE-ER and 10GBASE-ZR? I can't seem to find any.
