What Is FTTX? How Does It Differ from FTTP, FTTH, and FTTC?

2022-9-25

Part I. What’s FTTX?

FTTX refers to all types of fiber infrastructure including fiber to the home (FTTH), fiber to the premises (FTTP), fiber to the curb (FTTC), and fiber to the node (FTTN).

What Is FTTX?

Part II. FTTH vs FTTP vs FTTC vs FTTN

1. FTTH/FTTP

FTTH stands for fiber to the home and is synonymous with FTTP (fiber to the premises). They both refer to a fiber optic cable running directly from the Internet Service Provider (ISP) to a home or business location.

2. FTTC

FTTC stands for fiber to the curb and refers to a fiber optic cable run to the curb near the user with a copper ethernet cable connecting the fiber at the curb to the final location.

3. FTTN

FTTN stands for fiber to the node and refers to a fiber optic cable running to service a large area with copper ethernet cables connecting each location in the service area to the node.

Part III. FTTX Solution

Now, we will take the example with VSOL FTTX solution to help you know how FTTx works exactly.

As shown in the following diagram, it’s a full process of FTTx with PON technology from ISP to CPE.

The NMS(Network Management System) can manage devices and handle problems. The OLT will transfer the electronic signals into optical signals. It unlinks to the switch and downlinks to the ONU.

The terminal equipment depends on the networking methods and applications. For instance, when it comes to FTTH with cabling at home, ONU that transfers the optical signals into electronic signals should be placed on the users’ end.

If you adopt VSOL ONU HG323ACT, you can enjoy a WiFi network, CATV, POTS, etc. The ODN is the transmission medium between OLT and ONU.
