Talking about Fiber Optic Cable
Fiber optic cable
Optical fiber cable (optical fiber cable) is a communication cable, composed of two or more glass or plastic optical core, the fiber core is located within the protective coating, covered by plastic PVC outer casing. The signal transmission along the internal fiber generally uses infrared rays. In January 2013, Cuba to carry out communications changes, opening fiber-optic cable to increase foreign channel cited concern.
China from the mid-1970s began fiber optic cable research, almost simultaneously with foreign countries, and in 1977 developed the first quartz fiber. China's large-scale communications construction needs driven, China's fiber optic cable industry has developed rapidly, has been formed from the optical fiber preform to fiber optic cable products complete industrial chain. China's optical fiber and cable business production and technical strength has also developed rapidly, product development capabilities and technological innovation capability to further improve. China has become the world's second largest fiber optic cable country, all aspects of the world's advanced level.
From January to November 2007, China's optical fiber and cable manufacturing industry achieved total industrial output value of RMB 29,771,661 thousand, up by 33.22% over the same period of last year. The accumulated sales revenue of products reached 28,422,739 thousand yuan, up by 38.13% over the same period of last year. The total profit of 1,785,178 thousand yuan, an increase of 63.34% over the same period last year.
With the deep development of China's village project, light into the copper back (cable to replace the copper cable) irreversible trend and the Expo and other information technology under the pull of China's fiber and cable industry will maintain a steady growth trend. And more noteworthy is that 3G large-scale construction and FTTH gradually start, will become China's optical fiber and cable industry, the long-term development of the elements, will promote China's fiber optic cable industry into a new round of growth cycle.
The difference between fiber and cable
First: there are differences in material. Cable to metal (mostly copper, aluminum) for the conductor; fiber to glass fiber as a conductor.
Second: the transmission signal is different. The cable is an electrical signal. Fiber optic transmission of optical signals.
Third: there are differences in the scope of application. Cable is now used for energy transmission and low-end data transmission (such as telephone). Fiber is used for data transmission.
Cuba opened the first submarine fiber optic cable, making the data unilaterally into the Cuban speed has been improved. Although there is still a long way to go to achieve the goal of "people's real freedom of the Internet", it is indeed a tangible step in the path of "change" in Cuba. At the same time, the Cuban television station on the 20th for the first time simultaneously broadcast foreign radio company's television program, which in Cuba nearly 50 years time is the first time.
Cuba can be said that the last one in the Western Hemisphere connected to the fiber optic cable countries, but also the world's lowest rate of one of the countries. Previously, Cuba's network services were mainly connected via satellite systems, and the speed was very slow. About 16% of the Cubans can access the Internet, these people are mostly because of the work and learning process using the network, but most of the domestic LAN, will be subject to many restrictions. Only 2.9% of Cubans can browse the rest of the world's web pages in the country.
