Genuine SFP-10G-SR modules identified as 'GE ZX' and non-functional in Catalyst C9500-48Y4C
The poster's Cisco Catalyst C9500-48Y4C switches (IOS XE 16.12.04 after an upgrade) refuse to work with a batch of genuine Cisco SFP-10G-SR modules (VID V03, serials AVD2231D3TE and AVD2231D3RW): 'show inventory' lists them as 'GE ZX' instead of 'SFP+ 10GBASE-SR' and the ports stay non-functional. On other C9500s running IOS XE 16.9.3, SFP-10G-SR-S modules (VID V01, serials AVD2147DCD3/AVD2147DCDC) show correctly. 'show idprom interface TwentyFiveGigE1/0/27 detail' for a failing module reports 'Transceiver Type: = GE ZX (23)', PID SFP-10G-SR, Vendor Name 'OEM', Vendor OUI 00.00.00, CLEI COUIA8NCAA, Cisco part number 10-2415-03, date code 19/12/13, Encoding 8B10B and 'Nominal bitrate = OC12/STM4 (600 Mbits/s)' with 40 km single-mode reach values, i.e. the EEPROM content of a 1G ZX optic. The poster asked whether the modules should be returned.

This looks like a bug, or mis-programmed modules - worth raising with Cisco TAC. I didn't find any matching entry in the bug search tool.
Can you post the full 'show idprom interface <PORT> detail' output?
Once you've swapped the SFP, swapped the fiber patch and upgraded the firmware, the only thing left is TAC and an RMA.
As a workaround I installed third-party 10G SR modules in production and left the failing Cisco modules in place elsewhere so I can open a TAC case on them.
