KDDI Domestic Ethernet Services

Service Menu (Bandwidth Guarantee Type)

The bandwidth guarantee type service provides a point-to-point Private Leased Circuit connection.

  • KDDI Powered Ethernet is recommended when connecting more than two locations by establishing a multipoint-to-multipoint connection.

10Mbps, 100Mbps

The PLC service is for short-distance communication and requires both locations to be connected in an area served by the same local switch.

1Gbps

The PLC service for medium- and long-distance communication provides a point-to-point connection within distances up to 500km. The 1Gbps PLC service is the first end-to-end type service for medium- and long-distance communication in Japan. It meets the needs of the usage, that require storage backup lines for disaster countermeasures and high-capacity lines for research and development purposes.
