Refer To the Graphic. What Type of Cabling Is Shown?

Answer:

1. STP
2. UTP
3. Fiber
4. Coax

The correct option is C. the cable used with respect to the graphic is the fiber. A network cable includes different types of cables such as,

• Fiber cable properties are it is flexible, thin, and transparent like a stand of glass outside insulated by the plastics.
• In STP four pairs of wires are used, each wire wrapped in a foil shield and then wrapped in a foil or overall metallic braid.
• Coaxial cable uses a conductor made of copper and around the copper conductor, it is insulated by flexible plastic sheets.
• In UTP, four pairs of colored wires are used which are intertwined and encapsulated in a plastic sheath.

Fiber optical cable:

The fiber optic cable consists of a core, jacket, and buffer. The composition of the core is made from thin strands of plastic or glass that cover the long distance to carry data. outside the core, there is cladding that wrapped the core, and the cladding is wrapped by a buffer then outside the buffer, there is the jacket. The function of these parts is,

• Core carries the data in the form of light.
• The cladding function is reflection. It reflects the light to the core.
• Buffer is protected from leaking.
• The outer part is the jacket that protects the cables from physical damage.

Fiber optical cable is mostly used to transfer data over a long distance with high speed. The maximum distance is 40 Kilometers and the speed is 100Gbps. It is completely immune to electromagnetic radiation. Light is used by fiber optics to send data; light is reflected in the fiber from one point to another point. On the basis of the number of beams of lights, there are two types of fibers,

• Single-mode fiber
• Multimode fiber.
