三、翻译成英文： **Differences between Router and Optical Modem: How to Choose and Use Them Correctly?** In our homes, whether it's broadband connections or other forms of network services, they often involve equipment such as optical modems and routers. These two devices have their own specific functions and importance, and the correct selection and use of them are crucial for network performance and user experience. So, let's take a look at the differences between routers and optical modems, as well as how to choose and use them correctly. **I. Differences between Routers and Optical Modems** 1. Definition and Functional Differences Optical Modem: An optical modem is a terminal device on the user side of fiber access, mainly responsible for converting optical signals into digital signals for our network devices to use. It is an interface device that converts optical signals into Ethernet transmission. Router: A router is a network-level device used to connect multiple networks or devices, enabling the transmission and sharing of network data. It not only has network connection functions but also network management functions such as data forwarding, firewall, access control, etc. 2. Working Principles Differences The optical modem is mainly responsible for completing the decoding task of the fiber optic and then performing basic operations such as network transmission and data processing. The router, on the other hand, is responsible for routing the traffic of multiple devices to the corresponding addresses. **II. How to Correctly Choose and Use** 1. Selecting the Right Equipment When purchasing optical modems and routers, it is necessary to choose based on your own needs and budget. Generally, the optical modems provided by operators meet standards, but routers can be chosen based on personal usage requirements, such as brand and model. Stability, transmission rate, and network coverage are all parameters to consider. 2. Correct Setup and Installation The setup and installation of optical modems and routers require certain professional knowledge. Generally, operators provide corresponding services and technical support during broadband installation. For routers, users can follow the instructions or network tutorials for setup and installation. Correct settings ensure the normal operation of the equipment and the security and stability of the network. 3. Daily Maintenance and Troubleshooting
