Hi,
Not all 3rd party vendor SFPs work with Cisco switches. You may want to try a different SFP from a different vendor or purchase one from a Cisco partner/reseller.

Hi,
Not all SFPs are not compatible with any Cisco switch. You must buy a compatible SPF for the Cisco Switch.
Here are the list and guide for Cisco 4948E
Here is the Cisco tool to find the best suitable SPF:

Hi,
Both Switches are different. What is IOS version on both switch? Also, share SFP details.
Have you trined "service unsupported-transceiver" command?
