If you already have some optics available that you would like to try, you can insert them into the port and do "debug hal show optic-info" at the CLI to check if that particular optic is supported or not. That being said, please be aware that the recommendation here is that you do not use optics that are unsupported.
Or just go to the official Extreme webpage and choose the product and scroll down and you'll find the datasheet with all the information that you need.
