Indus Towers Senior Field Service Engineer Interview Questions and Answers

To determine the location of a broken fiber, I would use an OTDR and then fix it by splicing or replacing the damaged section.

• Use an Optical Time Domain Reflectometer (OTDR) to analyze the fiber and locate the break.

• Once the break is identified, the damaged section can be spliced back together or replaced.

• Splicing involves fusing the two ends of the fiber together using a fusion splicer.

• If the break is severe or in an ...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 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
