Top 10 Questions for Cable Maintainer Interview

1. What is the primary role of a Cable Maintainer?

The primary role of a Cable Maintainer is to maintain and repair cables, ensuring uninterrupted connectivity and optimal performance of telecommunications networks.

2. Describe the different types of cabling you have worked with. How are they used in network infrastructure?

Copper Cabling

• Unshielded Twisted Pair (UTP): Used for data transmission over short distances, such as within buildings.
• Shielded Twisted Pair (STP): Provides better protection against interference, suitable for longer distances and demanding applications.

Fiber Optic Cabling

• Single-Mode Fiber (SMF): Transmits data over long distances at high speeds, ideal for backbone networks.
• Multi-Mode Fiber (MMF): Used for shorter distances, such as within data centers.

3. What tools and equipment do you use to troubleshoot and repair cable faults?

• Cable Tester: To identify faults and measure cable performance.
• TDR (Time Domain Reflectometer): To locate specific faults along the cable.
• Splicing Equipment: For repairing fiber optic cables.
• Terminating Tools: For connecting cables to ports and equipment.

4. Explain the different methods used for splicing fiber optic cables.

• Fusion Splicing: Joining fibers by melting them together, resulting in a permanent and low-loss connection.
• Mechanical Splicing: Using connectors to join fibers, providing a faster and less precise method.

5. How do you ensure the safety of yourself and others while working with electrical cables?

• Wear appropriate PPE (Personal Protective Equipment), including gloves, safety glasses, and safety harness.
• Follow lockout/tagout procedures to isolate electrical energy before working on cables.
• Be aware of potential hazards, such as arc flash and electrical shock.

6. What is the difference between a passive and active component in a cabling system?

• Passive Components: Do not require external power, such as cables, connectors, and patch panels.
• Active Components: Require external power, such as switches, routers, and modems.

7. Describe the process of installing a new cable run.

• Plan the route and determine cable type and length.
• Obtain necessary permits and permissions.
• Prepare the cables and terminate the ends.
• Install the cables, following proper techniques and industry standards.
• Test and certify the cable run.

8. What are the common techniques used to terminate fiber optic cables?

• Cleaving: Creating a clean and perpendicular break in the fiber.
• Polishing: Smoothing and polishing the fiber end to minimize signal loss.
• Splicing: Joining two fibers together using fusion or mechanical splicing.
• Terminating: Attaching connectors to the fiber ends.

9. How do you troubleshoot and resolve common issues in a cabling system?

• Identify the problem, such as slow connectivity or cable damage.
• Perform tests using cable testers and other diagnostic tools.
• Repair or replace faulty components.
• Document the troubleshooting and repair process.

10. Describe your understanding of network topologies and their advantages.

• Bus Topology: All devices connected to a single cable, simple to implement but can be susceptible to single-point failures.
• Ring Topology: Devices connected in a closed loop, provides redundancy but requires careful planning and troubleshooting.
• Star Topology: Devices connected to a central switch or hub, simplifies troubleshooting and provides scalability.
