KDDI and Rostelecom launch 10G wavelength service between Japan and Europe

By Telecom Lead Team: KDDI America, the US
division of KDDI Corporation, and Rostelecom, a Russian carrier, announced the
launch of 10Gbps wavelength service with the shortest latency between Japan and


KDDI Corporation and Rostelecom signed an
agreement last year for upgrade and modification with Russia-Japan Cable
Network (RJCN) and Transit Europe-Asia (TEA) to construct 10Gbps wavelength
resources between Japan and Europe using the shortest route via Russia.


RJCN/TEA route is 7-100msec shorter than
the Indian Ocean route and 45-60msec shorter than the US/Atlantic Ocean route.
The RJCN upgrade was completed in January 2012.


KDDI has closely cooperated with Rostelecom
Operation team to improve the network quality and has been operating at 100
percent availability on IPLC service between London and Tokyo (total length
10,000km or over 6,200 miles).


This broadband network connects Tokyo and
Europe with the shortest distance. It is the best solution to address various
demands such as low latency transmission and two-way real-time communications.


The network will be ideal for large
capacity contents delivery including video transmission service supporting
broadcast of various events in Europe and Africa. RJCN was not affected by the
earthquake in Japan because this cable is laid in the Sea of Japan. The cable
has contributed to customers’ demand for core backbone towards Europe and the
U.S. This network will continuously play an important role to provide customers
with cable diversity.
