FTTR (Fiber to the Room) FAQ
Q1: What is FTTR (Fiber to the Room)?
A: FTTR (Fiber to the Room) is an all-optical home networking solution that extends optical fiber from the home gateway into every room, replacing traditional Ethernet or Wi-Fi-only distribution.
Unlike conventional home networks, FTTR combines fiber optics with distributed Wi-Fi access points to deliver consistent Gigabit connectivity throughout the home.
Typical components include:
FTTR Master ONU
FTTR Slave ONU
Invisible optical fiber
Optical splitters
Wi-Fi 6 / Wi-Fi 7 access points
FTTR is designed to provide stable, high-speed connectivity for modern smart homes and small offices.
Q2: How does an FTTR solution work?
A: An FTTR network uses a Master ONU as the central gateway and connects multiple Slave ONUs through optical fiber.
The basic workflow is:
The Master ONU receives broadband service from the GPON/XGPON network.
Optical fiber extends the connection to each room.
Slave ONUs convert optical signals into Wi-Fi and Ethernet services.
Users enjoy seamless roaming and full-home wireless coverage.
Compared with traditional Wi-Fi extenders, FTTR uses fiber as the backbone, reducing signal loss and maintaining consistent bandwidth across all rooms.
