The difference between Gigabit Ethernet port and 100M Ethernet port

The Gigabit Ethernet port on the optical modem is used to connect to a router or computer, and the 100M port is used to connect to a set-top box to watch IPTV. A Gigabit port is a 10/100/1000M adaptive Ethernet port, and a 100M port is a 10/100M adaptive Ethernet port.

Nowadays, optical fiber to the home has become popular and has become the way for most users to access the Internet at home. Currently, operators provide broadband and IPTV, which are connected to the optical fiber through an optical fiber. Cats provide both services. (Recommended learning: PHP video tutorial)

The Gigabit network port can provide a maximum network speed of 1000M and a download speed of up to 1000/8=125MB/s. The 100M network port can pass a maximum network speed of 100M and can provide a maximum download speed of 100/8=12.5MB/s.

In our current home broadband networking model, the core device that provides the home network is the router.

When the home broadband is greater than 100M, the Gigabit wireless router we purchase needs to be connected to the Gigabit network port of the optical modem, which can provide higher download speeds.

The main reason why optical modems have 100M and 100M network ports is that the price of 100M network cards is higher than 100M network cards, and 100M network ports can fully meet the needs of IPTV services.

Higher network speed requires higher cost. The price of Gigabit network port is higher than that of 100M network port. When operators provide optical modems, considering the cost, they often only provide them to Users have an optical modem with one Gigabit network port and several 100M network ports. The Gigabit network port is used by users to access the Internet, and the 100M network port is used for IPTV.

The IPTV service we currently use, based on the bandwidth required for 4K high-definition video, requires about 40Mbps of network bandwidth, so it is sufficient to provide a 100M network port for the IPTV service.

The initial setting is that only the Gigabit network port (or the 100M network port to improve the Internet service) can access the Internet, and the other network ports are closed or can only watch IPTV, but now there are also some optical mode settings Both 100M and 1000M can surf the Internet and watch IPTV. When connecting the optical modem interface, users should pay attention to whether the connection is a Gigabit network port.
