Velankani Software Network and Planning Engineer 5 Interview Questions, Process, and Tips

Fttx network architecture refers to fiber-to-the-x network architecture, where x can be home, curb, building, etc.

• Fttx network architecture involves deploying fiber optic cables to deliver high-speed internet and other services to various locations.

• The architecture can be categorized as FTTH (fiber-to-the-home), FTTB (fiber-to-the-building), FTTC (fiber-to-the-curb), etc.

• FTTH is the most common type, where fiber optic ...read more

Both ArcGIS and QGIS have their own strengths and weaknesses for fttx planning.

• ArcGIS is a powerful tool with advanced features and capabilities, but it comes with a higher cost.

• QGIS is an open-source tool that is free to use and has a strong community support, but it may lack some advanced functionalities compared to ArcGIS.

• The choice between ArcGIS and QGIS ultimately depends on the specific needs and budget of the p...read more

Yes, CO locations can be replaced with proper planning and network optimization.

• CO locations can be replaced by consolidating equipment and resources to more efficient locations.

• Proper network planning and optimization can ensure minimal disruption to services during the replacement process.

• Consider factors such as coverage, capacity, and redundancy when planning the replacement of CO locations.

A passive splitter is a device used to split an optical signal into multiple outputs without amplification. Two stage splitters are used for better signal distribution.

• Passive splitter does not require power source for operation

• Two stage splitters provide better signal distribution compared to one stage

• Two stage splitters are used when more outputs are needed or when signal loss needs to be minimized

The maximum length from OLT to ONT in a PON network is typically around 20 kilometers.

• The maximum distance can vary depending on the type of fiber optic cable used and the quality of the components.

• In general, the maximum length is around 20 kilometers for standard PON networks.

• For longer distances, signal boosters or amplifiers may be required to maintain signal integrity.

• Factors such as signal loss, attenuation, and ...read more

To estimate the BOQ for 600 households, consider factors like household size, equipment needed per household, and budget constraints.

• Calculate the average number of equipment needed per household based on the requirements (e.g. routers, cables, switches, etc.)

• Consider the quality and quantity of equipment needed for each household

• Estimate the total cost of equipment based on the average number of equipment per househol...read more

Flexnap fiber is a type of fiber optic cable that is more flexible and easier to install compared to BAU fiber.

• Flexnap fiber is designed to be more flexible, making it easier to bend and install in tight spaces.

• BAU fiber, on the other hand, is more rigid and less flexible, requiring more careful handling during installation.

• Flexnap fiber may have a higher cost due to its specialized design and ease of installation.

• BAU ...read more

1:128 splitters can be used in PON networks, but are typically avoided due to signal loss and network performance issues.

• 1:128 splitters divide the signal into 128 outputs, leading to significant signal loss

• This can result in degraded network performance and reduced reach

• Smaller splitters like 1:32 or 1:64 are more commonly used for better signal distribution

FDH stands for Fiber Distribution Hub, it is a central point in a fiber optic network where fibers are terminated and connected.

• FDH is used to distribute fiber optic cables to multiple locations in a network.

• It typically consists of fiber optic splice trays, distribution panels, and connectors.

• FDHs are often located in central offices, data centers, or outdoor cabinets.

• They play a crucial role in managing and organizin...read more

No, flexnap fiber cable cannot be hard spliced.

• Flexnap fiber cable is designed to be spliced using fusion splicing techniques.

• Hard splicing can cause damage to the fiber and result in signal loss.

• It is recommended to use fusion splicing or mechanical splicing for flexnap fiber cable.

• Hard splicing may void the warranty of the cable.

A 2:8 splitter is a device used in networking to split a signal into 8 outputs, with 2 inputs.

• 2:8 splitter is used in networking to divide a signal from 2 inputs into 8 outputs.

• It is commonly used in applications where a single signal needs to be distributed to multiple devices.

• The ratio of 2:8 indicates the number of input ports to output ports in the splitter.

• Examples of use include distributing internet connection f...read more
