Sr Fiber Engineer Interview Questions and Answers for Freshers

OLT stands for Optical Line Terminal and ONT stands for Optical Network Terminal.

• OLT is a device used in fiber optic networks to aggregate and distribute data to multiple ONTs.

• OLT is typically located at the service provider's central office or data center.

• ONT is a device used at the customer's premises to convert optical signals into electrical signals for communication.

• ONT is responsible for connecting the customer's devices to the fiber optic network.

• OLT and ONT work toget...read more

The losses in OFC are due to absorption, scattering, and bending.

• Absorption loss occurs due to the conversion of optical power into heat energy.

• Scattering loss occurs due to the scattering of light by impurities and imperfections in the fiber.

• Bending loss occurs when the fiber is bent beyond its minimum bend radius.

• Other losses include splice loss, connector loss, and modal dispersion.

• The total loss in OFC is typically measured in decibels per kilometer (dB/km).

There are 12 colour codes in OFC.

• OFC stands for Optical Fiber Cable

• Each colour represents a specific fiber type or function

• The 12 colour codes are standardized across the industry

OFC is distributed from OLT to ONT through fiber optic cables.

• Optical Fiber Cables (OFC) are used to transmit data from OLT to ONT.

• The OFC is connected to the OLT at one end and to the ONT at the other end.

• The OFC can be either aerial or underground depending on the location.

• The OFC can be single-mode or multi-mode depending on the distance and bandwidth requirements.

• The OFC can be spliced or terminated using connectors depending on the installation method.
