Fiber Optic Cables
The best broadband service is by these factors are most important to you. If the money is not the problem, the best plan is likely to be the fastest. If money is the primary concern, the best broadband might be the least expensive service. If it's convenient, defined the best may be simple, call your cable TV company; or perhaps customer service is your number one concern, making your choice of the Internet Service Provider (ISP) the most important factor in choosing the best broadband provider. It's likely that it will be a combination of these factors taken in different degrees that will define the best broadband for you, so let's take them one at a time.

The optical transmission has the advantages of light weight, small size, transmission distance, large capacity, small signal attenuation, anti-electromagnetic interference, has been widely used in a variety of network. With the twenty-first century will be the advent of fiber optic cable will certainly constitute the main body of China's network data transmission, telecommunications, cable television and other private network. In the choice of cable, twisted-pair cable and coaxial cable, can be roughly determined by visual inspection and simple test its performance advantages and disadvantages.

As is usually the case in many networks, specific architectural characteristics, installed environment and particular applications may dictate the deployment of one type of cable over the other. The topic "How to choose the right fiber optic cable" has become more valued than ever. To satisfy the installation requirements in a poor environment or prevent the fiber from outside damages, such as water, fire or animal biting etc., nowadays many fiber optic cables with different functions have been designed and launched in the market which includes tight buffered cable, loose tube cable, distribution cable, ribbon cable and so on. Today, we will introduce one of the most common used fiber cables in the outdoor environment - the loose tube cable.

Because, this period of communication network household cable lines, part of the outdoor, part of indoors, requirements and their way of laying optical fiber cables new requirements. These places the fiber capacity requirements will continue to grow, but still rules to follow, everything will depend on the needs of users. To have potential demand forecast puts the fiber optic cable, obviously will produce waste and the backlog of funds.

From wikipedia, we can have a simple understanding about Fiber Breakout Cables. Well, breakout-style fiber optic cable, also called breakout cable or fan out cable by some people, which is an optical cable containing several jacketed simplex optical fibers package together inside an outer jacket. This differs from distribution-style cable, in which tight-buffered fibers are bundled together, with only the outer cable jacket of the cable protecting them. The design of breakout-style cable adds strength for ruggedized drops, however the cable is larger and more expensive than distribution-style cable. Breakout cable is suitable for short riser and plenum applications and also for use in conduits, where a very simple cable run is planned to avoid the use of any splice box or spliced fiber pigtails.

Plastic Optical Fiber (POF) is a large core step-index fiber with a typical diameter of 1 mm. This large size makes it easy to couple lots of light from sources and connectors and do not need to be high precision. As a result, typical connector costs are 10-20% as much as for glass fibers and termination may be as easy as cutting with a razor blade! Being plastic, its also rugged and easy to install without fear of damage. POF has always been "lurking in the background" in fiber optic; it's a specialty fiber useful for illumination and low speed short data links. There is now a greatly increased interest in POF, as R&D has given it higher performance to go along with its ease of installation and low cost.

Single mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single mode fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width.

In the long-distance optical communication systems, fiber optic transmission characteristics should be the long-term stability, especially long distance buried fiber optic cable and submarine cable systems, long life put forward higher requirements for fiber optic cable. Generally land cable service life and hope to have more than 20 years of safe use, while the submarine cable is required to improve its service life to 25 years, and its mean time between failure of 10 years required. Therefore, how to enxtend the life of the cable, how to properly use the fiber optic cable, is an important technical issues people care about, from the aspects of the structure of the cable under the talk about how to extend the service life of the cable.
