Hello,

which IOS have you tried ? It looks like 12.2(20)SE is required for the 100Base-LX SFP...

Sometimes these switches only like Cisco gbics and have problesm with non OEM gbics .

Hi,

If its a Cisco GBIC, it should get recognised as you meet the IOS requirement. Is it the only one with which u r facing the problem or some others too.

There are some fake GBICS in the market to with exact look alike as the cisco one. Please open a TAC request along with the model and product number of the GBIC u r using and TAC should be able to help you in this matter.

The 1000BASE-ZX SFP (Cisco product number GLC-ZX-SM=) is supported on the Catalyst 3750:

Cisco Optical SFP Transceiver Compatibility Matrix

http://www.cisco.com/en/US/products/hw/modules/ps5000/products_device_support_table09186a0080212cba.html

List price in the US is the same as for the 1000BASE-ZX GBIC (Cisco product number WS-G5487=)

It's possible that the information you have found has not been updated yet. I believe the ZX SFPs were among the last ones to become available. The Release Notes in the link below are the first ones to mention this SFP, they refer to it as "new hardware" (versus the SX and LX SFPs):
