Fiber optic cable has developed into a standard component in global communications infrastructure. It is immune to electromagnetic interference and radio frequency interference which makes it among the best cable mediums. Optical fiber has the ability to transport signals over long distances which is why it is utilized in most networks. In its simplest form optical fiber is actually a thin glass strand which is often used to transmit a pulse of light. As the light travels it is contained in the glass by cladding. Multiple strands are bundled together inside of a jacket which is what forms the resulting cable. While each kind of Fiber drawing machine is essentially the same, you will find unique differences which must be considered when deciding which one is best for a particular application.
The first thing to consider is if single mode or multi-mode optical fibers are required. Multi-mode fiber allows the signal to travel along multiple pathways within the glass strand. Single mode fiber requires laser technology for sending and receiving data. This offers it the opportunity to carry a single signal four miles which is the reason it is usually used by telephoning cable-television providers. One thing to bear in mind is the fact that electronic infrastructure necessary to manage single mode transmissions are far more expensive than multi-mode which explains why multi-mode is usually the best choice for geographic area networks.
The next thing to consider is whether or not loose tube or tight buffered optical fiber is the greatest solution. Loose tube designs include the glass core and clouding with a thin protective acrylic coating. This is recognized as the most basic usable form for installation purposes. Loose tube optical fibers are usually preferred when high strain counts are needed along with larger protective jackets. Some newer designs for indoor fiber are now using loose to constructions too. Overall, tight buffered remains the popular option if the fiber-optic cables will be installed in a building. It is because the protective jacket is directly within the fiber strand which makes it easy to work with and eliminates the need of a breakout kit.
The last consideration in choosing Fiber drawing machine should be the kind of connectors which will be used. You can find a fairly large number of different connector styles on the market however most distributors only accommodate SC and ST style connectors. SC connectors push in then click when seated. ST connectors are also called the bayonet style and are pushed in and twisted to lock the cable in place.
Considering that the inception of lightwave optical communication with fiber, the main focus continues to be on the technology for very long-distance telecommunication applications. And that is certainly why single mode glass optical fiber has been the most popular channels for such applications. Due to the ever-increasing necessity for more bandwidth, the information communication market xttaes risen for the forefront in fiber optic communication. After several rounds of competition with other technologies, Ethernet is actually the winner for LAN networks.
Silica-based multimode fiber is adopted to supply an affordable optical link with a combination of transceivers based on Vertical Cavity Surface-Emitting Laser (VCSELs). However it is far from the very best answer to distribute such FTTH cable production line even just in premises and home networks or interconnections. Why? Plastic optical fiber (POF), with its its large core, has been supposed to become the office and home network media. Plastic optical fiber’s large core allows using cheap injection-molded plastic connectors which can significantly lower the complete link cost.
But POF features its own problems. The most crucial obstacle is plastic fiber’s high signal loss (attenuation). PMMA has been used since the light guiding core for commercially available step-index POF and PMMA’s attenuation is about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications in excess of 100m.
