Optical fiber carries much more information than conventional copper wire and is in general not subject to electromagnetic电磁的 interference and the need to retransmit signals. Most telephone company long-distance lines are now of optical fiber.

• Compare that with the mainland of China. Over the next decade, it plans to pour some $100 billion into telec omm unica tio ns equipm e nt. I n a way, China's backwardness is an advantage, because the expansion occurs just as new technologies are becoming cheaper than copper wire systems. By the end of 1995, each of China's provincial capitals except for Lhasa will have digital switches and high-capacity optical fiber links.This means that major cities are getting the basic infrastructure to become major parts of the information superhighway superhighway, allowing people to log on to the most advanced services available.

optical fiber cable:
An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.
There are two main types of material used for optical fibers: glass and plastic. They offer widely different characteristics and find uses in very different applications. Generally, plastic fiber is used for very short range and consumer applications, glass fiber is used for short/medium range (multi-mode) and long range (single-mode) telecommunications. Optical cables transfer data at the speed of light in glass. This is the speed of light in vacuum (真空) divided by the refractive index (折射率）of the glass used, typically around 180,000 to 200,000 km/s, resulting in 5.0 to 5.5 microseconds（微秒） of latency per km. Thus the round-trip delay time for 1000 km is around 11 milliseconds(毫秒).

Short Answer Questions
2. What do you think of the relationship betweenman and nature?
Tips Man has the “blood ties” with nature. Mankind has to depend on nature for his food, medicine, shelter, clothing and other necessities to be able to survive. However, due to industrialization and economic development, man does not live in harmony with nature anymore. While transforming nature for his own sake, man has been over exploring and using the natural resources, resulting in such problems as global warming, soil erosion, shortage of fresh water, and sandstorms. Man has suffered a lot from the problems.
