Jmc Works Interview Questions and Answers

Clearances from utilities are necessary to avoid interference and damage to the optical fiber path.

• To prevent accidental damage to the fiber optic cables during maintenance or construction work by utility companies.

• To ensure that there is no interference from existing utility lines that could affect the performance of the optical fiber network.

• To comply with safety regulations and standards to prevent accidents and ensure the reliability of the network.

• To avoid costly repairs...read more

The minimum and maximum depth of bore and trench varies depending on the specific project requirements and local regulations.

• Minimum depth of bore and trench is typically around 24 inches to ensure proper protection and support for the fiber optic cables.

• Maximum depth of bore and trench can range from 36 inches to 60 inches, depending on factors such as soil conditions, road crossings, and utility clearances.

• Local regulations and project specifications should always be consul...read more

The width of conduit used for fiber placement varies depending on the number of fibers being installed.

• Conduit width typically ranges from 1 inch to 4 inches for fiber placement.

• The width is determined based on the number of fibers being installed and the type of fiber optic cables used.

• For example, a conduit width of 1 inch may be sufficient for a small number of fibers, while a width of 4 inches may be needed for a larger installation.

Boring involves drilling a hole underground for installation, while trenching involves digging a trench for laying cables or pipes.

• Boring involves drilling a hole underground using specialized equipment, while trenching involves digging a trench using machinery like excavators.

• Boring is typically used when minimal disruption to the surface is desired, while trenching is used when a larger area needs to be excavated.

• Boring is more expensive but can be faster and less disruptiv...read more

Trenching is generally more cost effective than boring for fiber planning.

• Trenching is typically cheaper upfront as it requires less specialized equipment and labor compared to boring.

• Boring may be more expensive initially due to the need for specialized machinery and skilled operators.

• However, in certain situations where trenching is not feasible or cost-effective, boring may be the preferred method.

• Factors such as soil conditions, existing infrastructure, and project timeli...read more
