NMT Engineer Interview Questions and Answers

LSPM OTDR splicing is a technique used in fiber optic network engineering to connect two optical fibers using a fusion splicer.

• LSPM stands for Large Scale Photonic Matrix.

• OTDR stands for Optical Time Domain Reflectometer.

• Splicing is the process of joining two optical fibers together.

• LSPM OTDR splicing involves using a fusion splicer to melt the ends of two fibers and then fusing them together.

• This technique ensures low loss and high reliability in fiber optic connections.

Total loss in splicing of OFC can be calculated using a formula.

• Total loss is the sum of splice loss and attenuation loss.

• Splice loss is caused by the mismatch between the two fibers being spliced together.

• Attenuation loss is caused by the reduction in signal strength as it travels through the fiber.

• The formula for total loss is: Total Loss = Splice Loss + Attenuation Loss.

• Loss can be measured in decibels (dB).

OTDR machine is a device used in fiber optic testing to measure the characteristics of an optical fiber.

• OTDR stands for Optical Time Domain Reflectometer.

• It sends a pulse of light into the fiber and measures the backscattered and reflected light.

• OTDR can determine the length of the fiber, identify any breaks or faults, and measure the attenuation and loss of the signal.

• It provides a graphical representation of the fiber's characteristics, known as an OTDR trace.
