Multimode fiber is used for shorter distances because the larger core opening allows light signals to bounce and reflect more along the way. The larger diameter permits multiple light pulses to be sent through the cable at one time, which results in more data transmission. This also means that there is more possibility for signal loss, reduction or interference, however. Multimode fiber optics typically use an LED to create the light pulse.
While copper wire cables were the traditional choice for telecommunication, networking and cable connections for years, fiber optics has become a common alternative. Most telephone company long-distance lines are now made of fiber optic cables. Optical fiber carries more information than conventional copper wire, due to its higher bandwidth and faster speeds. Because glass does not conduct electricity, fiber optics is not subject to electromagnetic interference and signal losses are minimized.
In addition, fiber optic cables can be submerged in water and are used in more at-risk environments like undersea cable. Fiber optic cables are also stronger, thinner and lighter than copper wire cables and do not need to be maintained or replaced as frequently. Copper wire is often cheaper than fiber optics, however, and is already installed in many areas where fiber optic cable hasn't been deployed. Glass fiber also requires more protection within an outer cable than copper, and installing new cabling is labor-intensive, as it typically is with any cable installation.
Fiber optics uses
Computer networking is a common fiber optics use case, due to optical fiber's ability to transmit data and provide high bandwidth. Similarly, fiber optics is frequently used in broadcasting and electronics to provide better connections and performance.
Military and space industries also make use of optical fiber as means of communication and signal transfer, in addition to its ability to provide temperature sensing. Fiber optic cables can be beneficial due to their lighter weight and smaller size.
Fiber optics is frequently used in a variety of medical instruments to provide precise illumination. It also increasingly enables biomedical sensors that aid in minimally invasive medical procedures. Because optical fiber is not subject to electromagnetic interference, it is ideal for various tests like MRI scans. Other medical applications for fiber optics include X-ray imaging, endoscopy, light therapy and surgical microscopy.
OPTICAL FIBER CABLE
The number of fibers in a cable varies from 4 to 96 (more number of fibers are provided upon request). OPtical fiber cables will generally undergo 4 processes of production line such as Coloring Line, Secondary Coating Line, SZ-Stranding Line and Sheathing Line.
Coloring Production Line:
Fiber coloring Process is carried out to mark the fiber. For easy identification of insdividual fiber inside the tubes, they are color coded. The colors have no influence. on the optical properties of the fibers. The fibers are colored using UV curable ink which are chosen as industry standard, easily in stripping, jointing and stability of optical loss under various stress.
Secondary Coating Production Line:
This process uses Polybutylene Terepthalate (PBTP) as tube material which extremely has good thermal, hidrolysis and mechanical properties. The tube contain fibers and are filled with special typical gel. Secondary coating or tubing process is used to protect the optical fibers during cabling and installation process.
SZ-Stranding Production Line:
Stranding process which is around polyethylene coated central strength member applies SZ-Stranding Method. The stranding is filled with jelly as flooding Compound to fill any space of the block the flow of the water into the cable.
Sheathing Production Line:
Sheathing line is an unit which its process protects the optical cable core from mechanical, thermal and chemical effects, associated with storage, installation and operation. The core covering is covered with the laminated Aluminium Polyethylene (LAP) sheath containing carbon black, to provide an electrical ground and moisture barrier. Sheathing also uses one corrugated steel tape. between inner and outer sheath to provide a mechanical protection. The sheath is ussually over printed to identity the type of cable of a particular point.
