Fiber optic cable has become a standard component in global communications infrastructure. It is immune 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 utilized in most networks. In its most basic form optical fiber is actually a thin glass strand which is used to transmit a pulse of light. As the light travels it is contained within the glass by cladding. Multiple strands are bundled together within a jacket which is what forms the resulting cable. While each type of secondary coating line is essentially the same, you will find unique differences which should be considered when deciding which one is the best for a certain application.
The first thing to consider is whether or not single mode or multi-mode optical fibers are required. Multi-mode fiber allows the signal to travel along multiple pathways inside the glass strand. Single mode fiber requires laser technology for sending and receiving data. This offers it the opportunity to have a single signal four miles which explains why it is usually used by telephoning cable-television providers. Something to keep in mind is that the electronic infrastructure necessary to manage single mode transmissions are significantly more expensive than multi-mode which is why multi-mode is truly the smart choice for local area networks.
The next thing to take into consideration is whether loose tube or tight buffered optical fiber is the ideal solution. Loose tube designs include the glass core and clouding having a thin protective acrylic coating. This is regarded as the most basic usable form for installation purposes. Loose tube optical fibers are usually preferred when high strain counts are essential in conjunction with larger protective jackets. Some newer designs for indoor fiber are now using loose to constructions also. Overall, tight buffered is still the more popular option if the fiber-optic cables will be installed in a building. It is because the protective jacket is directly over the fiber strand that makes it easy to work alongside and eliminates the need of a breakout kit.
The final consideration when selecting optical fiber proof-testing machine ought to be the form of connectors that might be used. You will find a fairly multitude 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 are pushed in and twisted to lock the cable into position.
Because the inception of lightwave optical communication with fiber, the focus has been on the technology for 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 necessity for more bandwidth, the data communication market xttaes risen for the forefront in fiber optic communication. After several rounds of competition along with other technologies, Ethernet is obviously the winner for LAN networks.
Silica-based multimode fiber is adopted to provide a cheap optical link with a combination of transceivers based upon Vertical Cavity Surface-Emitting Laser (VCSELs). However it is really not the most effective solution to distribute such Fiber drawing machine even just in premises and home networks or interconnections. Why? Plastic optical fiber (POF), with its its large core, has become anticipated to function as 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 has its own problems. The most important 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 all about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications of over 100m.
