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.

The Cisco N9K-X9464TX= switches support the 4x 10GE break-out mode to operate as 4 individual 10GE ports. This allows the line card to provide up to 144 10GE SFP+ ports. These switches are compatible with various Gigabit Ethernet SFP optical transceivers. All these fiber optic transceivers are available on Cozlink at really competitive prices. You can expect same day shipping on Cozlink. Not just optical transceivers, you can also find fiber optic pigtails and high speed cables for your choice on Cozlink.
