  • Achieves a network of low latency (via Access Point: about 56 microseconds one-way (*1), via Co-Location Area: about 4.7 microseconds one-way (*2))

Reliability (secure 99.999% availability)

  • A robust optional fiber ring is constructed network with totally separate backup routes and 99% buried cables (in preparation for large-scale earthquakes and such wide-area disasters)
  • Dispersed housing of user lines for connection (3 Access Points)

Scalability (secure scalability to ensure sufficient capacity)

  • Sufficient bandwidth is secured in the optical fiber ring network in preparation for future expansion (use 2nd wavelength for Co-Lo connection to external networks)
