The LRM looks like the way to go for you if you are limited by SFP+ as
the Andrew pointed out.
Only I'm not the OP :). Andrew is correct though, LX4 doesn't seem
available in SFP+.
The Cisco spec is for 220M at 500MHz fiber on LRM.

Older fiber is usually 200 Mhz.
The LX4 would be a better choice (more dispersion resistant) and max distance
of 300M.
I thought that the OP required an SFP+ on one

True, and I expect the fibers between our dorm to be no better than 200
MHz*km.

Greetings,
I have a 6509 with an X6716-10GE Card equipped with Cisco X2-10GB-LX4 10GE
modules and a Cisco 2960S-48TD-L Switch with two Cisco SFP-10G-LRM
modules.
LX4 and LRM are not compatible. LRM uses a single 1310nm laser,
LX4 uses four lasers around 1310nm and wdm

Much better to stick to standard transceivers (SR, LR, ER, ZR or DWDM).
That's easier said than done; if you need 10 Gbps but you only have

That's easier said than done; if you need 10 Gbps but you only have old
MMF available, your only choices for 30 meters are LX4 and LRM.
As we get to capacities higher than 10 Gbps you should not expect old

and no...
are you sure that its supported?
lx4 == wwdm optic == 4x2.5gbps channels using wideband muxing.
additionally, when looking at datasheets for x2 and sfp+ modules, one
will see that lx4 optic mentions 4 lanes, launching in the 1300nm
space and a separate pluggable for x2-10gb-lrm.
sfp+ only
I believe LX4 uses multiple wavelengths. This seems to confirm it. I don't
think you can mix those with anything else.
