3. Search the Internet for the brand and model of the light cat. Use a search engine and enter the brand and model of the light cat to see if there is a relevant official website or other reliable source of information.

4. Refer to the official website or other trusted channels. If you find the official website of Optical Modem or other credible information sources, check whether they provide detailed information about the Optical Modem device, purchase channels, authorized agents, etc.

5. Contact your network operator. If you suspect that the optical modem is a rogue device, you can contact your network operator, provide them with the details of the optical modem, and inquire whether it is a legitimate device.

6. Seek professional help. If none of the above methods find sufficient evidence, or you are unsure about your judgment, you can seek help from professionals, such as network security experts or the network operator's technical support team.
