PTCL Optical Engineer Interview Questions, Process, and Tips

Optical fiber splicing is the process of joining two fiber optic cables together.

• Splicing can be done mechanically or through fusion.

• Mechanical splicing involves aligning and securing the fibers with a splice connector.

• Fusion splicing involves melting the ends of the fibers together using an electric arc.

• Splicing is necessary for extending the length of a fiber optic cable or repairing a damaged cable.

• Proper splicing i...read more

Optical fiber splicing requires specialized equipment for precision and accuracy.

• Fusion splicer

• Cleaver

• Stripper

• Alcohol wipes

• Fiber holder

• Splice protection sleeves

The color scheme depends on the specific project and its requirements.

• Color scheme is determined by the project's purpose and goals

• Considerations include lighting conditions, contrast, and aesthetics

• Examples of color schemes include complementary, analogous, and monochromatic

• Color schemes can also be customized to fit a brand's identity

OTDR is used for testing and troubleshooting fiber optic cables.

• OTDR stands for Optical Time Domain Reflectometer.

• It sends a pulse of light into the fiber and measures the time and strength of the reflected signal.

• This information is used to locate faults, measure attenuation, and determine the length of the fiber.

• OTDR is commonly used in the telecommunications industry.

• It can also be used in other industries that use ...read more

OLT stands for Optical Line Terminal and is a device used in FTTH (Fiber to the Home) networks.

• OLT is responsible for converting optical signals into electrical signals that can be transmitted over copper wires.

• It is typically located at the central office or headend of the network.

• OLT communicates with the ONTs (Optical Network Terminals) at the customer's premises to provide internet, TV, and phone services.

• OLT can s...read more
