According to a research report by Infonetics, a consulting organization, the global cable broadband equipment market revenue in 2004 increased by 57% over the previous year, reaching 667 million US dollars.
The consulting agency pointed out that in 2004, the global wired cable broadband users increased by 22% to 41 million, and this market will continue to grow by 2008. North America is still the world's largest wired cable broadband market. In 2004, its number of users reached 22.4 million, an increase of 26% over the previous year, and it accounted for 55% of the global market. The Asia-Pacific region is in second place, with a global market share of 25%.
In the global wired cable broadband equipment market in 2004, Cisco's revenue and equipment port share exceeded 50%, and it was in an absolute monopoly position; Motorola ranked second in market share.

Statistics show that my country's copper demand has maintained a rapid growth rate in recent years, with a compound annual growth rate of 14.2% from 1998 to 2002, which is much higher than the growth rate of global copper demand. In 2002, my country's copper demand was 2.5 million tons, accounting for 17% of the total global demand, surpassing the United States and becoming the world's largest copper consumer.

Professor Richard Smalley of Rice University in the United States is working hard to develop a world's latest quantum wire.
The most research on this kind of quantum wire is Professor Smalley of Rice University in the United States. His successful 15-centimeter-long thin wire drawn from billions of carbon nanotubes represents the first step in a new type of wire that will completely change the transmission grid. This is a wire braided with carbon nanotubes, which can efficiently transmit electrical energy.

Recently, companies in the wire and cable industry in Anhui Province held a symposium in Hefei to exchange information on the development of the industry, analyze existing problems, and study countermeasures to accelerate development under the new situation. In recent years, the wire and cable industry in Anhui Province has grown significantly, and some places have become the towns and towns of cables. However, due to insufficient information exchange and lagging industry coordination, there have also been phenomena of excessive repetition of products, "long-term too long", and "short-term lack". In order to survive, some companies are competing to lower prices and even relax quality to reduce costs, causing losses to the company and users. In order to change this situation, experts believe that we should start with adjusting product structure, paying close attention to product quality and developing new products.

Hua Jiping, a well-known communications expert and chairman of the Optoelectronic Cable Branch of the China Electronic Components Industry Association, said in an interview that the current problems in the domestic optoelectronic cable industry are that it is not strong enough, and specialized enough.

Transistor is an important electronic device, its size shrinks twice every 18 months, now it is more than 100 nanometers, by 2010 it was only a few tens of nanometers. What is used to connect the components of this ultra-high-density integrated circuit? A few days ago, the nano-cable developed by Professor Shuhong Yu of the University of Science and Technology of China, which is only four thousandths the thickness of a human hair, provides a way to solve this problem.
