Fiber optic cable has turned into 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 ability to transport signals over long distances which explains why it is utilized in most networks. In its simplest form SZ stranding line is basically a thin glass strand that is utilized 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 can find unique differences which must be considered when deciding which one is the best for a certain application.

The first thing to consider is if single mode or multi-mode optical fibers are required. 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 gives it the opportunity to carry a single signal four miles which is the reason it is often employed by telephoning cable-television providers. One thing to be aware of is that the electronic infrastructure necessary to manage single mode transmissions are far more expensive than multi-mode which is why multi-mode is usually the best option for neighborhood networks.

The next thing to take into consideration is whether loose tube or tight buffered optical fiber is the best solution. Loose tube designs consist of the glass core and clouding using a thin protective acrylic coating. This is recognized as the most basic usable form for installation purposes. Loose tube optical fibers are typically 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 continues to be more popular option if the fiber-optic cables will be installed in a building. The reason being the protective jacket is directly within the fiber strand which makes it easy to do business with and eliminates the necessity of a breakout kit.

The final consideration in choosing secondary coating line should be the type of connectors that might be used. There are 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 known as the bayonet style and they are pushed in and twisted to lock the cable into place.

Considering that the inception of lightwave optical communication with fiber, the main objective has been on the technology for long-distance telecommunication applications. And that is certainly why single mode glass optical fiber continues to be the most preferred channels for such applications. As a result of ever-increasing necessity for more bandwidth, the information communication market has risen to the forefront in fiber optic communication. After several rounds of competition with some other technologies, Ethernet is obviously the winner for LAN networks.

Silica-based multimode fiber is adopted to provide a cheap optical link with a mix of transceivers based on Vertical Cavity Surface-Emitting Laser (VCSELs). However it is really not the very best solution to distribute this type of silica-based optical fiber even just in premises and home networks or interconnections. Why? Plastic optical fiber (POF), featuring its drvunx large core, continues to be supposed to become the office and home network media. Plastic optical fiber’s large core allows the usage of cheap injection-molded plastic connectors which could significantly lower the entire link cost.

But POF has its own problems. The most crucial obstacle is Fiber drawing machine. PMMA has been used 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 of over 100m.
