A fiber optic cable, also known as an optical-fiber cable or optical cables, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for different applications, for example, long distance telecommunication, or providing a high-speed data connection between different parts of a building.
Types of fiber cables ?
FTTH (Fiber to the home) fiber optic drop cable
FTTH (Fiber to the home) drop cable, the outer skin is generally black and white, the diameter is relatively small, and the flexibility is good; the cross section is 8-shaped, the reinforcing member is located at the center of the two circles, and the metal or non-metal structure can be used, and the optical fiber is located at the geometric center of the 8-shaped shape. The fiber inside the cable is mostly G.657A2 small bending radius fiber, which can be laid at a bending radius of 20mm.
Fiber optic drop cables are available in many different types. The three most commonly used fiber drop cables include flat drop cable, figure-8 aerial drop cable and round drop cable. They are typically small diameter, low fiber count cables with limited unsupported span lengths, which can be installed aerially, underground or buried. As it is used in outdoor, drop cable shall have a minimum pull strength of 1335 Newton’s according to the industry standard.
Because it small size and light in weight and good fiber optica cable price, the FTHH drop cable is suitable for application of fiber to the home. It can be out according to the distance of the site, increased the efficiency of the construction.Is suitable for entering the house by pipe or distribution openly.
Aerial fiber optic cables
Aerial fiber optic cables are fiber optic cables typically used in outside installation on poles. Because of the installation circumstances and environment where aerial fiber cables are usually installed, the design and composition of aerial fiber optic cables should consider protecting it from nature’s destruction and human damage or robbery.
Aerial fiber optical cable’s installation process is considerable easier to carry out, since it can used the already existent utility poles lines to be installed. This process consequently minimize it’s construction price and reduce it’s construction time.
This cables for the most part are utilized for subordinate and lower trunk level and generally used in flat terrain or lower fluctuation area. Aerial fiber optical cables can be easily damage by natural disasters, for instance hurricanes, typhoons, floods, tornadoes, ice ,etc. This disasters could easily affect the cable exterior force and mechanical strength. For that reason, the deterioration rate of aerial fiber optic cables are superior than the fiber optic cables that are directly put it underground and the fiber optical cables pipeline installed.
Duct fiber optic cables
Telecommunications companies rely on ducts fiber optic cables to build and improve their networks. Though not strictly required to place optical fiber, ducts fiber optical cables make it easier to set fibers properly and keep them functioning smoothly once installed.
Underground fiber optic cables
Underground fiber optic cables are cables directly burred on the ground, which allows underground transmissions and communications systems with no need for additional protection. These cables are strongly designed to resist environmental and climate factors that could influence it efficiency, such as soil acidity, heat and moisture. The underground fiber optica cable price is high than other type fiber cable because of its strong structure.
This cables delivers a consistently good quality performance in data, video, image and voice applications. The high flexibility and density of underground fiber optical cables design makes it convenient to use in many systems.
