Maintenance Agreement

[Press Release] 2000.4.18

KDD, NTT Communications Corporation (NTT Com), and Japan Telecom concluded at 3 p.m. (JST 4 p.m.) today in Singapore the APCN 2 (Asia Pacific Cable Network 2) Construction and Maintenance Agreement (C&MA), together with other 43 telecoms carriers.

The APCN 2 is a 19,000 km long optical fiber submarine cable network which links Japan, Korea, China, Taiwan, Hong Kong, Philippines, Malaysia, and Singapore in a ring configuration, and its service-in is scheduled for the end of September, 2001.

The APCN 2 is a highly reliable cable network suited for large capacity data transmission services, as the first cable system that has a self-healing function in the Asia Region, and is capable of restoring itself instantly with its ring configuration when a failure occurs in a part of the system. On the Japan side, it is to be landed at the two locations: Chikura (Chiba Prefecture: KDD) and Kitaibaraki (Ibaraki Prefecture: NTT Com).

Making the most of the latest WDM technology (note), its operation is to start with an initial circuit capacity of 80 Gbps or 160 Gbps (1,536 circuits or 3,072 circuits in 45 Mbps circuit equivalent), and the circuit capacity is upgradable up to 2.56 Tbps (49,152 circuits in 45 Mbps circuit equivalent) by augmenting landing station facilities gradually in the future.

In addition, by interconnecting it with the China-US Cable Network, the SEA-ME-WE 3 Cable, the Japan-US Cable Network under construction, and other cable systems, it is possible to construct a large-capacity, highly-reliable seamless network not only within the Asia-Pacific Region but with the United States, Europe, and other areas.

With the APCN 2, KDD, NTT Com and Japan Telecom are intending to meet the demands for large-capacity and high-speed communication services including ATM service as well as the IP-related communication requirements between major Asian countries.

(Note) WDM (Wavelength Division Multiplexing) technology
A wavelength-division multiplexing technology enables transmission of larger volume information, by placing simultaneously a large number of signals with various
wavelengths on a single optical fiber.
