China Unicom Corp. announced Wednesday the launch of a
terrestrial optical cable network connecting China, Mongolia and
Russia. The cable is joint effort with Mongolia's Railcom and
Russia's TransTeleCom Company, with China Unicom building the
section of the network connecting China and Mongolia.
At 7,500 kilometers in length, the cable is the shortest
terrestrial cable link between mainland Europe and Asia.
By adopting Synchronous Digital Hierarchy (SDH) technology, the
capacity for the first phase of the cable is expected to reach 622
megabits per second (Mb/s), according to Tian Wenke, general
manager of the Data and Fixed Communications Department of China
Unicom.
About 155 Mb/s have already been put into use, he said.
With a shorter length than other terrestrial cables, information
will be subject to fewer delays as it travels, Tian said. This is
an important feature for new businesses that are
time-sensitive.
Before the launch, international business had been conducted
mainly through satellite networks and submarine cable networks, but
the new terrestrial system will facilitate business with more
European and Asian countries.
"The terrestrial cable network and submarine cable networks are
complementary and help enhance the reliability of the networks,"
said Tian. "I believe with the launch of the terrestrial cable
network, much business that used to rely heavily on submarine
cables or satellites will be transferred to the new cable
network."
Telecom businesses based on optical cable networks usually
consist of IP phones, data transmission and Internet-based
services.
Tian believes that the launch of the cable will be conducive to
China Unicom's international business as it provides a new
alternative.
"It's a win-win deal for China, Mongolia and Russia as the cable
is going to meet the increasing demand for data transmission and
telecommunication demand, along with enhanced economic cooperation
between the three countries and Europe and Asia."
China Unicom plans to extend a similar terrestrial cable soon to
the Democratic People's Republic of Korea.
"We have obtained the license from regulators, but we don't have
an exact timeline," said Tian.
In another development, China United Telecommunications Corp.
Ltd., a listing arm of China Unicom in the domestic A-share market,
announced last Saturday that it plans to raise 6 billion yuan
(US$722 million) through share placements.
The company has reported revenues from its main businesses last
year reached 59.8 billion yuan (US$7.2 billion), up 31.2 percent
from a year earlier.
Pretax profits for 2003 stood at 24.8 billion yuan (US$3.0
billion), a rise of 7.5 percent year-on-year.
Net profit was 2.3 billion yuan (US$280.0 million), up 6.3
percent from the previous year.
