INDEXOptic fiber sees increases
Between January and April 2015, Chinese
optical communication companies have
produced 103 million kilometers of optical
cables, an increase of 15.25 percent
year-on-year according to data from a
Chinese institution of industry research.
Thedata shows that the optical cable output
from Jiangsu Province ranks first, with a 46.8
percent share of the national total output.
Jiangsu Province’s optical cable production
reached 48.2643 million core kilometers, an
increase of 13.53 percent year-on-year.
Hubei Province has produced the second
largest optical cable output, with 17.6539
million core kilometers and a year-on-year
increase of 22.27 percent, accounting for
approximately 17.13% percent of the total
amount.
Optical cable output from Chongqing
experienced
the
biggest
increase
compared with the previous year. In 2013,
Chongqing SDGI Optical Fiber Cable Co Ltd
invested in Fuling New District, to achieve its
target of producing 2 million core kilometers
of optical cables per year.
It brought new capacity for optical cable
production in Chongqing, and a total of
863,700 core kilometers optical cables have
been produced in the first four months, an
increase of 3,921.84 percent year-on-year.
Ropes going further
In March this year the crew of
Seabed
Worker
, a Norwegian deep retrieval vessel,
salvaged a motor from the Saturn V rocket
motor that powered Apollo 11. The motor
was at a depth of 4,600m and was retrieved
using a 44mm DynIce Warp synthetic rope
manufactured by Hampidjan Baltic in
Lithuania.
Seabed Worker
is specially designed for
salvage operations at extreme depths.
Among the ship's other achievements, it has
been used to salvage 1,400 tons of copper
from a sunken ship at a depth of 3,200m and
48 tons of silver from a wreck at 4,200m.
Hampidjan has twice supplied
Seabed
Worker
with DynIce ropes. Originally the
ship was supplied with a 4,200m length,
which was twice lengthened to bring it up
to 5,200m, and the most recent delivery
was 6,300m long and 44mm in diameter,
with breaking strength of 142 tonnes.
Steel wire rope at these depths would
be unable to support its own weight over
these extreme lengths. The rope on
Seabed
Worker
weighs 8.6 tons, compared to the 62
tons that a comparable length of steel wire
rope would weigh.
