KOREA’S KT Corporation has developed
technology to enable copper telephone
cables to provide Internet service at
speeds “never before accomplished”.
The company exhibited its technology
during the Mobile World Congress at the
end of February.
Many old buildings still use copper
telephone cables with optical cable or
unshielded twisted pair (UTP) cables to
provide an Internet service, but services
through copper wire using VDSL (very
high bit-rate DSL) are limited to
100Mbps.
KT has announced its FTTH-G solution,
said to provide a two-way service of at
least 200Mbps using a pair of telephone
lines. KT said download speeds could
be much faster than 200Mbps. For
example, download speed can be
300Mbps if the upload speed is reduced
to 100Mbps.
KT’s FTTH-G solution saves building
owners the cost of replacing copper
wires with more advanced cables, the
company said, and it will run a pilot
project for the technology in some older
apartment buildings in Gangnam district
to demonstrate the service.
“We will further enhance FTTH-G and
create a technology that provides at
least 300Mbps Internet speed next
year,” said a KT official. “We will utilise
various types of wires and enable old
buildings to provide Internet at giga-
bytes-per-second speeds.”

Cutting the fibre optic connecting costs by half
Fujitsu Laboratories Ltd and Furukawa Electric Co Ltd have collaborated to
develop a new multi-fibre optical connector to join and align multiple optical
fibres for optical interconnects.
The conventional method of connecting optical fibres is an expensive
process, requiring high-precision polishing to align the tips of the fibres.
Fujitsu Laboratories and Furukawa Electric have developed a connector that
can accommodate different lengths of optical fibre and which, with a spring
mechanism that obviates the need for the polishing process, will cut the
costs of connecting optical fibres by half.
This new connector is said to achieve performance on a par with
conventional connectors while simplifying the task of installing
high-capacity optical interconnects. It is anticipated that the technology will
increase data transmission speed between boards, so increasing overall
server performance.
