If the command show interface [INTERFACE] transceiver status is not available, try using show hw-module subslot 0/0 transceiver [SFP SLOT] status. Here’s an example.
Cisco4451#show hw-module subslot 0/0 transceiver 3 status
The Transceiver in slot 0 subslot 0 port 3 is enabled.
Module temperature = +24.316 C
Transceiver Tx supply voltage = 3357.2 mVolts
Transceiver Tx bias current = 13182 uAmps
Transceiver Tx power = -7.1 dBm
Transceiver Rx optical power = -32.2 dBm

If it is still not working for you, check the output of show logging. Verify if the SFP that you are using is compatible with your equipment. It should not say %TRANSCEIVER-3-NOT_SUPPORTED
Example:
000046: *Jun 5 2020 09:59:28.694 CDT: %TRANSCEIVER-6-INSERTED:iomd: transceiver module inserted in Gigabitethernet0/0/3
The output of show interface [INTERFACE] should not say media type is unknown media type. It should state the media-type if detected and compatible. In the example above, I am using GLC-LH-SMD= 1000BASE-LX/LH SFP transceiver module, MMF/SMF, 1310nm, DOM
The Transceiver Rx optical power should be between -3 to -8 dBm if interfacing within the same building or short-range optics. Long range optics can go a lot lower depending on distance. Anything less than -30 dBm is essentially no light received. The sample above shows no light.
