Terms and Conditions

Connected Terminals There is no limit on the number of terminals that can be connected on a single subscriber's line (number of terminals installed on a corporate or home LAN).
Time until Service Start The time it takes until customers can start using the service depends on the building (e.g. piping) and our equipment availability. Your understanding is appreciated.
When changing plans from B FLET'S to FLET'S HIKARI NEXT You cannot use the service when the changing work is in progress.
Moreover, some services may no longer be able to be used, or your equipment may need to be replaced or reset, etc. As well, separate installation charges will apply. Further, changing plans from B FLET'S to FLET'S HIKARI NEXT may involve other issues not mentioned here depending on the context. Click here to confirm details. For more details, make an inquiry by telephone.

It is 10BASE-T/100BASE-TX/1000BASE-T for Giga Mansion Smart Type/Mansion Giga Line Type/Mansion High-Speed Type/Business Type. The customer must prepare an Ethernet interface (LAN card, etc.) in the PC or other terminal device. (The customer must prepare the required LAN interface.)

* This information concerns the operation confirmation status of Internet connection etc. with FLET'S HIKARI NEXT, and does not guarantee operation in all environments.

Internet Protocol(IPv4) The Internet protocol (IPv4) will use PPPoE. We will send PPPoE driver software to customers with set installation dates the day before the installation date by methods such as shipping. If you are using Mac OS X as your computer's OS, use the PPPoE function that comes standard in the OS. It is also possible to use PPPoE software provided by the customer, or routers supporting PPPoE. However, for questions about setting up such equipment, refer to the software vendor or the manual included with the product.
  1. A check of equipment may be made for the optical subscriber's line installation before the actual equipment is set up. The results of the check may mean "FLET'S HIKARI NEXT" is unavailable.
  2. Installation of piping and equipment in the customer's building may be required when setting up the subscriber's optical line. Customers will be responsible for the costs of this installation work. If the building is an apartment or tenanted building, permission from the apartment or building owner, or board of owners association, will be required for installation and use of shared equipment.
  3. The subscriber's service may be temporarily interrupted due to maintenance and servicing of our own equipment and facilities.
  4. The Mansion Type VDSL System may experience lower transmission speeds and periods of downtime due to DSL initiated events such as the status of multi-unit equipment, interference with other lines, and the influence of transmission equipment in the customer's home.

  • To use the Internet, a separate contract for the service is required with your provider. Please note that providers are different for each type of service.
  • Maximum communication speeds indicate maximum values based on technical standards and do not necessarily represent actual usage speeds. Internet speeds during use may slow significantly due to the user environment (such as terminal device specifications) and line congestion.
  • In order to achieve communication speeds exceeding 100 Mbps, equipment that is capable of communication speeds of 1 Gbps is required (compatible LAN cables, computer terminals, etc).
Internet (IPv6)
  • For Internet (IPv6 PPPoE) connections, additional equipment such as an IPv6 tunnel adapter* may be required.
    * A device for PPPoE connectivity for Internet (IPv6 PPPoE) connections
  • For IPv6 IPoE Internet communication, the High-Speed Type maximum communication speeds are 100 Mbps for sending data and about 1 Gbps for receiving data. The maximum speed of about 1 Gbps only applies to IPv6 IPoE Internet communication (such as viewing websites that support IPv6 addresses).
  • Not all websites on the Internet support IPv6 Internet.

Precautions on wireless LAN usage
  • When using a wireless LAN, set up security features (such as communication encryption) to prevent third-party falsification of data, identity theft, etc.
  • Communication may be lost or communication speeds may significantly slow if there is interference such as signal-blocking obstructions between wireless LAN segments or if there are devices using the same wireless frequency band.
  • The Wi-Fi LAN transmission distance varies with the usage environment and signal quality.
Precautions on Giga Mansion Smart Type use <About Internet (IPv6 PPPoE) connectivity>
