Service Menu/Bandwidth Warranty Type

Bandwidth Warranty Type Bandwidth Choice Type

Bandwidth warranty type is a wide-area, warranty-type exclusive line service which connects two locations by the Ethernet.

KDDI Powered Ethernet is recommended for multipoint-to-multipoint connections for more than two locations.

10 Mbps/100 Mbps

To receive this service for short-distance communication, the two locations to be connected must both be in an area managed by the same base station. For Kanto area, 10 Mbps can also be used for medium-distance communication within a prefecture or between prefectures.

1Gbps

This service for medium- and long-distance communication enables two locations within the distance of 500 km to be connected. Among 1 Gbps exclusive lines, this is the communication industry's first end-to-end type service for medium- and long-distance communication. It meets the demand for storage backup lines as disaster measures as well as the needs of academic organizations which require high-capacity lines for research and development.

10Gbps

This is a 10 Gbps super broadband service optimal for customers' needs for increased information such as backbone lines for ISPs or content providers, and data center connection lines for large companies. Development of exclusive lines that guarantee 100% end-to-end band availability is possible at a reasonable capacity unit price compared to GbE lines or domestic super high speed digital exclusive lines.
In addition to the standard "Dual Class", "Single Class", an affordable service that has a non-redundant configuration in the relay transfer zone, is also available.
