I have two 10GB modules one in a Nexus 7010 and the other in a 3560E-12SD.
SFP-10G-SR= 10GBASE-SR SFP+ transceiver module for MMF, 850-nm wavelength, LC duplex connector
X2-10GB-LX4= 10GBASE-LX4 X2 transceiver module for MMF, 1310-nm wavelength, SC duplex connector
The modules are different wavelengths and aren't talking to each other with normal MMF. So, do I just need a mode conditioning patch cable for the X2-10GB-LX4 module? Or will I need a new transceiver on one end?
Thanks,
Mike Gross

Patch conditioning cable.

Are you sure, Leo?
I think a new transceiver is needed. Mode conditioning patch cables are for moving from one core size to another - most typically used when moving from 50 nm to 62.5 nm core multimode fiber. If the wavelengths of the transceivers don't match up, a patch cable of any flavor won't rectify that incompatibility. You still need to receive on the same wavelength your transmit.
