We have a Cisco 7600 router with multiple GBIC modules.
Can you please confirm if there is a difference in a GBIC module marked as WS-G5486 1000BASE-LX and another marked as WS-G5486 1000BASE-LX/LH.
We have found that on one of our circuits, the LX cuases packet loss, but the LX/LH works fine.
The part numbers are the same and all the Cisco documentation we have suggests both modules are identical.
Can you please confirm.
