Some fttp need to pick up a light cat, and some directly connect to the home.

In fttp, optical signals sent by operators to users must be converted into electrical signals by using onu, which belongs to ftth mode of optical fiber network, that is, optical fiber directly enters the home.

The other way is fttb+lan, where the optical fiber goes directly to the building, and then the network cable is connected to the user through the integrated line in the building. This is also a kind of fttp, and the uplink switch is also the olt equipment of pon network.

There is also a broadband network cable that directly enters the home, which belongs to the metropolitan area network. The operator puts the building switch in the corridor of the residential building and then connects it to the user's home through the network cable. This method is similar to fttb+lan, except that the upstream switch is not a pon device.
