Indus Towers Field Service Engineer Interview Questions and Answers

Optical fiber works on the principle of total internal reflection of light.

• Light is transmitted through a core made of glass or plastic

• The core is surrounded by a cladding layer with a lower refractive index

• When light enters the core at an angle greater than the critical angle, it reflects off the cladding and stays within the core

• This allows for high-speed data transmission over long distances

• Examples include fiber op...read more

Optical fiber works on the principle of total internal reflection of light.

• Light is transmitted through a core made of glass or plastic

• The core is surrounded by a cladding layer with a lower refractive index

• When light enters the core at an angle greater than the critical angle, it reflects back into the core

• This allows the light to travel long distances without significant loss of signal

• Used in telecommunications, inte

The number of fibers and tubes in a 48f fiber cable and its color code.

• A 48f fiber cable typically has 6 tubes with 8 fibers in each tube.

• The color code for fiber cables is standardized as per TIA-598-C.

• The color code for the fibers in a tube is typically blue, orange, green, brown, slate, white, red, and black.
