  2. Content : • Indoor fiber optic cables • The benefits of indoor Fiber Optic Cable • The features of indoor Fiber Optic Cable • Tight-Buffered Cable • Consists of optical fiber cable • Other Cables

  3. Indoor fiber optic cables: • To protect the fibers from mechanical stress during and after installation. • To be more flexible. • To meet standard cods [such as national electric code (NEC) and any other building codes].

  4. The benefits of indoor Fiber Optic Cable: • Minimisesweight and cable installation • Minimisesnumber and size of conduits • Provides maximum number of cables per conduit • Ensures system compatibility and interoperability • Complete range of cables • Fast and accurate fiber identification • Easy to strip the fibers • Easy installation by laying and pulling

  5. The features of indoor Fiber Optic Cable: • Small cable diameter • Produced to industry specification • Soft buffer tubes • Color coded fibers • Low friction jacket on backbones cables

  6. Tight-Buffered Cable • The tight-buffered fiber optic cable is designed for indoor applications. It contains a number of individually buffered fibers surrounding a central strength member, with an overall protective jacket.

  7. Tight Buffered Fiber Cable: • Used in indoor applications. • Each fiber is individually encapsulated in 900 µm diameter plastic buffer structure. • Enables direct plugging with connectors. • Resists for moisture and temperature effects.

  8. The fiber buffer is a 900-µm diameter plastic cover surrounding the optical fiber's 250-µm coating.

  9. The functions of the consists of optical fiber cable : Write Note Core: This is the light transmission area of the fiber, either glass or plastic. The larger the core, the more light that will be transmitted into the fiber. Cladding: The function of the cladding is to provide a lower refractive index at the core interface in order to cause reflection within the core so that light waves are transmitted through the fiber. Coating: Coatings are usually multi-layers of plastic applied to preserve fiber strength, absorb shock and provide extra fiber protection. These buffer coatings are available from 250 microns to 900 microns.

  10. Fiber optic cable tight buffer • The buffer provides each individual fiber with protection from the environment as well as physical support. • Tight-buffered cable is more flexible than most loose tube cable and thus has a smaller bending radius. On the other hand, it is more expensive than loose tube cable with the same fiber count.

  12. : Fan-Out Cable A fan-out cable is a high-buffered cable terminated with connectors. Each individual fiber has either a 900-µm or 3-mm jacket, depending on the application. The 900-µm jacket is deployed where the cable will be terminating in a fiber patch panel The 3-mm type is used where the cable connects directly to the light wave equipment.

  13. Other Cables 1- Self-supporting Aerial Cable: A loose tube cable designed for use in aerial installations. It dose not require a messenger for support. The cable is designed with a heavy strength member (usually Kevlar) and jacket. A special version of this cable called the all-dielectric self-supporting cable is used near high voltage lines. 2- Submarine Cables: A loose tube cable designed for underwater submersion. It has a heavy armor jacket and may contain copper pairs to provide power for in-line optical amplifiers. 3- Military Cables 4-Industrial Cables 5-Special Purpose cables
