[c-nsp] SFP info

No impact, it should work. You can connect LX transceivers back to back;
iirc, minimum patch length is somewhere around 0.5 to 2 meters.

> Is that I can use only SX SFP for Back to back connectivity with routers.

No, LX or BX are OK too. Only with ZX or other long-haul optics you
might need an attenuator.

That depends on what the MUX supports, I guess... SX is generally used
on short distances since the optics are cheaper.
