It may be possible to request an optical fiber cable for a building not currently wired. Even in buildings services are already provided, the lead-time may be prolonged due to availability for the dark fibers. For the vertical cable, the numbers of lines or PD plates vary by building. Please contact us for details.

Optic cable network

An optical fiber cable network of our own has been installed within the Otemachi-Marunouchi-Yurakucho area, and about 70 percent of buildings in the area are served with the optical fiber cable network. Accordingly, secure and inexpensive yet high-speed telecom environment is available even on short notice. It is also possible to harness the office spaces of dissimilar buildings into a uniform LAN environment.

※The buildings to be constructed in the future will also be harnessed with an optical fiber cable network.
