Fiber optic cable has become a standard component in global communications infrastructure. It is immune to electromagnetic interference and radio frequency interference which makes it one of the best cable mediums. Optical fiber has the capacity to transport signals over long distances which is why it is utilized in most networks. In its simplest form FTTH cable production line is basically a thin glass strand which is used to transmit a pulse of light. As the light travels it 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 optical fiber is essentially the same, you will find unique differences which must 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 of the glass strand. Single mode fiber requires laser technology for sending and receiving data. This offers it the ability to have a single signal four miles which is why it is usually utilized by telephoning cable-television providers. One important thing to keep in mind is that the electronic infrastructure necessary to manage single mode transmissions are considerably more expensive than multi-mode which is why multi-mode is truly the smart choice for neighborhood networks.
The second thing to consider is if loose tube or tight buffered optical fiber is the best solution. Loose tube designs include the glass core and clouding having 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 required together with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions as well. Overall, tight buffered remains the more popular option once 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 with and eliminates the need of a breakout kit.
The final consideration when choosing SZ stranding line ought to be the type 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 called the bayonet style and are pushed in and twisted to lock the cable into place.
Considering that the inception of lightwave optical communication with fiber, the focus continues to be on the technology for very long-distance telecommunication applications. And that is why single mode glass optical fiber has become the most preferred channels for such applications. Because of the ever-increasing necessity for more bandwidth, the data communication market has risen to the forefront in fiber optic communication. After several rounds of competition with some other technologies, Ethernet is actually the winner for LAN networks.
Silica-based multimode fiber is adopted to offer an inexpensive optical link with a combination of transceivers based on Vertical Cavity Surface-Emitting Laser (VCSELs). However it is not the most effective solution to distribute this kind of silica-based optical fiber even in premises and home networks or interconnections. Why? Plastic optical fiber (POF), with its drvunx large core, has been expected to be the office and home network media. Plastic optical fiber’s large core allows using cheap injection-molded plastic connectors which may significantly lower the complete link cost.
But POF features its own problems. The most important obstacle is FTTH cable production line. PMMA has been utilized as 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 more than 100m.
