Hello, everybody!
Now the import and finance of routers in the home is self-evident, you must now have a question, what is the difference between a router and an optical modem?
What is the difference between a router and an optical modem?
Optical modem: indicates the modem function. "Modulation" is a key step in signal processing, this is an essential device for accessing the Internet. It is generally provided by a broadband carrier.
An optical modem is a key device that modulates Ethernet digital signals to optical fibers. It is connected to a computer using a network cable and connected to the remote office of a carrier using an optical fiber. Generally, an ONU that uses the PON technology is a common optical modem, and certainly, there are other optical modems that do not use the PON technology.
Connect to the device through telephone lines and optical fibers, and then connect the device to the wireless router through network cables.
In addition, if the user is newly built in recent years, generally, the operator will connect the optical fiber to the building, and the user can directly connect the network port on the wall of the home to the wireless router to enjoy high-speed broadband.
Router: a device that provides the route switching function. The routing function can be regarded as the function of connecting devices on different network segments (Ethernet).
For example, if you have multiple computers in your home and need to form a small LAN, but the carrier promises you only one Internet access quota, you need a router to connect the devices in your LAN to the carrier's network.
Similarly, if you only want to access a LAN terminal by yourself and do not want the terminal to be accessed by people from the carrier (Internet), you can configure the router to meet this requirement.
Now, do you get what is the optical modem and router?
