What is FTTR(Fiber To The Room)?

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. The promotion of “dual gigabit” coordinated development has brought about the upgrade of gigabit home broadband. FTTR (Fiber to The Room) technology, by directly extending the optical fiber to each room of the user, further upgrades the traditional fiber-to-the-home to fiber-to-the-room, and provides a new Gigabit network coverage solutions, which will be one of the technical directions for future Gigabit home broadband upgrades.

The FTTR technical solution is to carry out home networking through optical fiber media, deploy FTTR main gateways in distribution boxes or key 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 connected 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. Gigabit network coverage. The optical network is composed of optical cables, optical splitters and other components, which together build the infrastructure of the home intranet. The network management platform is responsible for collecting home network information and summarizing and reporting it, so as to fully realize the operation and maintenance management of the home Gigabit network

The main components of the FTTR network include ONUs, optical splitters, fiber optical cables, and optical fiber panels. ONU is an all-in-one device with WiFi6 routing.

Main ONU：connect to OLT uplink through XG(S)-PON or 10G EPON, undertake Gigabit/10G fiber-to-the-home, and provide downlink optical routing interface.

Slave ONU：Connect to the master ONU upwards through indoor fiber optical cables, and provide Internet access services for terminals downwards.

Optical splitter：realize the coupling, branching and distribution of optical signals.

fiber optical cables： realizes long-distance optical signal transmission. PS: When using the original network cable to upgrade FTTR, it is required to use Cat5 network cable 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.

Compared with traditional networking FTTR has certain advantages:

  • Full coverage. Lay optical fiber to each room, adopt WIFI6 Internet access technology, the measured speed of each room can reach 1200Mbps;
  • 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, and the service life is up to 30 years.

With the large-scale commercial use of FTTR networking technology, it is bound to fully release the many advantages of wired networks, bringing faster, better, and more reliable information access channels to our lives and offices. The FTTR all-optical networking mode is not only the inevitable development direction of Gigabit home networking, but also an opportunity for operators to realize innovation and upgrade of wired services.

Fiber to The Room (FTTR) Solution

  • As 200 Mbps or higher bandwidth becomes the mainstream and requirements for services such as online education, video, VR, e-Sports, and smart office increase sharply, users need Wi-Fi that supports high bandwidth, low latency, wide coverage, and multi-user concurrent access, driving operators to focus on services and experience in home network construction.
  • Whitepearl’s fiber to the room (FTTR) solution extends fibres to rooms and provides various gigabit Wi-Fi 6 master/slave FTTR units, all-optical components, and optical cable construction tools, enabling users to enjoy stable gigabit Wi-Fi experience in every corner of rooms at every moment.
  • In addition, Whitepearl’s FTTR solution uses device-cloud synergy to improve operators’ broadband service quality from three aspects: all-optical experience, zero frame freezing in video and VR services, and smart O&M.
