Fiber Optic Cable
Daily Practice Sheet
swer the Following questions
1. State whether the following statement are TRUE or FALSE
1. The physical arc of fiber optic cable is limited ( )
2. An optical fiber cable contains only one optical fiber. ( )
3. Guided media is also known as Wired Media or Bounded Media ()
4. A twisted pair cable consists of two insulated copper wires. ( )
5. Coaxial Cable gives a high bandwidth and excellent noise immunity​

Answer 1

Answer:

1. true

2.false

3.true

4. true

5. true

Explanation:

1.The optical fibers are difficult to splice, and there are loss of the light in the fiber due to scattering. They have limited physical arc of cables. If they are bended alot they break easily.  

2. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light.

3.   It is also referred to as Wired or Bounded transmission media because  Signals being transmitted are directed and confined in a narrow pathway by using physical links.

5. Coxaial cables are coated which prevents the noise from disturbing.

Answer 2

Answer:

1 true

2.false

3.true

4.true

5.true
