With the continuous acceleration of the transformation process in the digital age, it is the general trend
to increase the construction of 5G networks and gigabit optical networks. FTTR (Fiber-to-the-Room)
network provides new Gigabit network coverage solutions, which will be one of the technical directions
for future Gigabit home broadband upgrades. This article provides some information about FTTR.
What is FTTR?
FTTR refers to the technical method for optical fiber access when the optical fiber is laid to the
remote node. In addition, FTTR is a new coverage mode of the home network in the gigabit era
and technological evolution and upgrade of home networking. With low latency, high quality, and
high stability, FTTR achieves WiFi 6 Gigabit coverage throughout the home.
FTTR Network Solution
The FTTR network solution is to carry out home networking through optical fiber media, deploy

FTTR main gateways in distribution boxes or locations, take the main gateway as the core, and
form an FTTR optical network through optical splitters and single-core bidirectional optical fibers.
The FTTR master gateway is connected to the OLT in the uplink and to multiple slave optical
routers in the downlink through optical fibers and optical splitters. The optical router supports
Gigabit Ethernet ports and Wi-Fi 6 and enters each room through optical fibers to realize wired
and wireless connections in each room of home users.
The network management platform is responsible for collecting home network information and
summarizing and reporting it to fully realize the operation and maintenance management of the
home Gigabit network.
FTTR Network Components
 Main ONU: Connect to OLT uplink through XG(S)-PON or 10G EPON, undertake Gigabit/10G
fiber-to-the-home(FTTH) and provide a downlink optical routing interface.
 Slave ONU： Connect to the master ONU upwards through indoor fiber optic cables, and
provide Internet access services for terminals downwards.
 Optical Splitter： Realize coupling, branching, and distribution of optical signals.

 Optical Fiber: It has long-distance optical signal transmission, low attenuation, and no
electromagnetic interference (EMI). Its bandwidth can continue to evolve to more than
100Gpbs, meeting the demands of future high-bandwidth services. Note: When using the
network cable to upgrade FTTR, it is required to use Cat5 or Cat6 network cable for home
broadband. If you use a Cat5 network cable, you need 8 cores.
 Optical Fiber Panel：Complete the access and port output of the dual-core optical fiber, meet
the requirements of the bending radius of the optical fiber and provide safety protection for
the fiber core.
Benefits of FTTR: Light up a new era of Gigabit
 Full Coverage: Lay optical fiber to each room and adopt WiFi 6 Internet access technology.
The measured speed of each room can reach 1200Mbps. FTTR delivers Gigabit bandwidth to
the room.
 Full Swim: Use intelligent roaming technology to realize non-perceived switching and the
delay is less than 20ms.
 Easy to Manage: Intelligent management, one-click detection of WiFi network status, and
remote repair.

 Green and Environmental Protection: Using micro-optical fiber instead of network cable, the
wiring cost is lower, green, and environmentally friendly.
 Low Latency: FTTR ensures low latency at the premises and is not disrupted by radio
interference. It has a stable signal and high-quality broadband Internet access.
Applications
FTTR is used in cloud VR, 4K/8K video, online education, online office, e-sports, smart office, IoT,
CCTV, telemedicine, etc.
Conclusion
Looking forward to the future, FTTR can build a leading home information infrastructure for
thousands of homes with its technical superiority. It has ultra-gigabit bandwidth, seamless indoor
roaming, non-perceptual switching, and an optical network not susceptible to interference.
