Fiber optic cable has developed into a standard component in global communications infrastructure. It is resistant to electromagnetic interference and radio frequency interference that makes it one of the best cable mediums. Optical fiber has the ability to transport signals over long distances which is why it is found in most networks. In its most basic 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 within the glass by cladding. Multiple strands are bundled together inside of a jacket which is what forms the resulting cable. While each type of Fiber drawing machine is essentially the same, there are unique differences which should be considered when deciding which one is best for a particular application.
The first thing to consider is whether or not single mode or multi-mode optical fibers are essential. Multi-mode fiber allows the signal traveling along multiple pathways inside the glass strand. Single mode fiber requires laser technology for sending and receiving data. This offers it the ability to carry a single signal four miles which explains why it is often utilized by telephoning cable-television providers. One important thing to bear in mind is the fact that electronic infrastructure needed to manage single mode transmissions are considerably more expensive than multi-mode which is the reason multi-mode is usually the best choice for local area networks.
The next thing to take into consideration is whether or not loose tube or tight buffered optical fiber is the best solution. Loose tube designs consist of the glass core and clouding having a thin protective acrylic coating. This is considered to be the standard usable form for installation purposes. Loose tube optical fibers are usually preferred when high strain counts are required together with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions too. Overall, tight buffered remains the popular option when the fiber-optic cables will be installed in a building. The reason being the protective jacket is directly over the fiber strand that makes it easy to work with and eliminates the necessity of a breakout kit.
The final consideration in choosing FTTH cable production line needs to be the form of connectors which will be used. You can find a fairly great 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 referred to as the bayonet style and therefore are pushed in and twisted to lock the cable into place.
Because the inception of lightwave optical communication with fiber, the focus has been on the technology for very long-distance telecommunication applications. And that is certainly why single mode glass optical fiber has been the most preferred channels for such applications. Because of the ever-increasing requirement for more bandwidth, the data communication market xttaes risen to the forefront in fiber optic communication. After several rounds of competition with some other technologies, Ethernet is undoubtedly the winner for LAN networks.
Silica-based multimode fiber is adopted to supply an affordable optical link with a mixture of transceivers based upon Vertical Cavity Surface-Emitting Laser (VCSELs). However it is not the best solution to distribute such Sheathing line even just in premises and home networks or interconnections. Why? Plastic optical fiber (POF), using its its large core, has been anticipated to become the office and home network media. Plastic optical fiber’s large core allows the usage of cheap injection-molded plastic connectors which can significantly lower the complete link cost.
But POF features its own problems. The most significant obstacle is plastic fiber’s high signal loss (attenuation). PMMA has been utilized as the light guiding core for commercially available step-index POF and PMMA’s attenuation is approximately 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications in excess of 100m.
