Fttx Planning Engineer Interview Questions and Answers

Answers to questions related to FTTX network, GPON and EPON, GIS in network, and AUTOCAD commands.

• FTTX network is a fiber optic network that delivers high-speed internet, TV, and phone services to homes and businesses.

• GPON and EPON are two different technologies used in FTTX networks. GPON is more popular due to its higher bandwidth and longer reach, while EPON is cheaper and simpler to implement.

• GIS (Geographic Information System) is used in network planning and management t...read more

OTDR uses wavelengths of 1310 nm and 1550 nm to find fiber cut and fiber losses.

• OTDR (Optical Time Domain Reflectometer) is used to locate fiber cuts and measure fiber losses.

• OTDR sends a pulse of light into the fiber and measures the time and intensity of the reflected signal.

• 1310 nm wavelength is used for shorter distances and 1550 nm for longer distances.

• Fiber losses can also be measured using a light source and power meter.

• Light source emits a known amount of light and po...read more

BOQ stands for Bill of Quantities. It is a document that lists all the materials, labor, and equipment needed for a construction project.

• BOQ is used to estimate the cost of a project.

• It helps in determining the quantities of materials required for a project.

• BOQ is prepared by a quantity surveyor or an estimator.

• It includes details such as item description, quantity, unit of measurement, and cost.

• BOQ is an important document for tendering and procurement processes.

TIR stands for Total Internal Reflection. It is a phenomenon where light is reflected back into a medium instead of being refracted out of it.

• TIR occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle.

• It is used in fiber optics to keep the light signal within the core of the fiber and prevent loss of signal.

• TIR is also used in prisms and lenses to redirect light.

• The critical ...read more
