How to determine what types of optical transceivers for Cisco switches?

1. Finding the corresponding optical module compatibility matrix via Cisco official website. 

2. On the running switches, enter the privileged mode and input # "show idprom interface gi1 / 0/48" command, you can query the optical module model and serial number, If not, try to input other two commands: xuxic or show idprom int g2/6

3. Checking the type and port based on the specification, it can be used as long as it is gigabit SFP optical module interface. But the specific models to be decided according to the actual demand, such as type, the actual use of distance, single-mode or multimode, single fiber or dual fiber etc. Welcome to consult Cozlink engineer.

Summary
