Problem with X2-LR trancievers on Catalyst 4500 IOS Version 15.0(2)SG9

[sergiu.slivinski]

We have a Supervisor V-10GE with two X2 trancievers, so the problem is no link when I loop the trancievers. Help me plz. 

sh int trans

Are you looping the transceiver back locally (near the device) or at the far end (at the other end of the link)?  The reason I ask is that the receive levels are showing attenuation.  Are you using a singlemode fiber jumper?  

[sergiu.slivinski]

So I make loop localy using single mode patchcord.
