According to Penn State engineers, transmission rates of 100 gigabits per second are possible today over copper. But only on distances of less than 100 meters. And only with high-end Category 7 copper cables. These Ethernet cables are made up of four pairs of twisted wires shielded to reduce crosstalk. The Penn State technology could provide an alternative to glass fiber optics cables in computer datacenters where distances between systems are not too big. In other words, it would be possible to interconnect servers inside a building at speeds similar to the ones provided by more expensive fiber optic cabling.

Furukawa Electric Co. Ltd. and Tohoku University Graduate School have jointly introduced a medical application made of copper alloy. This development refers to an apparatus that uses copper shape memory alloy and aims to correct ingrown nails. What the apparatus does is to insert an alloy plate at both sides of the nail correcting its curvature. Tohoku University is currently using the instrument on a pilot basis, however, Furukawa is planning to start selling it within this fiscal year. The company expects to sell a significant volume of the newly developed instrument as about 10 million people in Japan suffer from ingrown nails. -
Furukawa Magnet Wire Co. Ltd., a subsidiary of Furukawa Electric Group, announced that it has expanded its facility in Malaysia. Production capacity of its TEX-E, trilayer insulated wire, which is principally used in rechargers for computers and mobile phones, has been doubled. The company expects that demand will increase in China and other emerging markets in the medium to long term. In addition, it was reported that Furukawa Electric increased its stake in Chongqing Changhua Automobile Harness Co. Ltd., the China-based wiring harness assembler, to 65% from its previously held 50% share.

Four major manufacturers of wire and cable are set to increase their level of capital investment in this fiscal year. The companies are expected to make large investments within emerging country markets, which promise growth over the medium to long term. Another area of investment is the field of smartphone components. Sumitomo Electric Industries Ltd., SWCC Showa Holdings Co. Ltd. and Furukawa Electric Co. Ltd. will expand capital investment "significantly", while Fujikura Ltd., will do so only "slightly".

February 2010—Siemon now offers 40+Gb/s SFF-8470 4X Passive Copper cabling products. These SFF-8470 copper cable assemblies support high-speed interconnect applications such as high-performance computing (HPC), enterprise networking, and network storage systems. The low latency assemblies support data transfer rates from 2.5Gb/s to 10+ Gb/s per lane. Siemon’s 8470 cable assemblies feature a shielded wafer construction in which the signal conductors are directly attached to the connector’s contacts, eliminating a printed circuit board and enhancing noise-resistance to maximize signal integrity. The twin-axial shielded cable conductors are laser-welded, reducing cross-talk and jitter to support 10+Gb/s data rates. SFF-8470 die cast back shells and latches are interoperable with all compliant interfaces. The 8470 product supports a wide array of data protocols and interfaces, including InfiniBand SDR, DDR, and QDR, Ethernet 10GBaseCX4, and 40GBaseCR4. These cables also support FibreChannel, RapidIO, Myrinet, SAS, SATA, Aurora, VITA VXS, and XAUI/XAUI-2 IO interface links, as well as SONET/SDH. Product options include 24 to 30 wire gauges and various assembly lengths.
