100 Interview Questions and Answers for Outside Plant Cable Engineer

  1. What is your experience with different types of cable (fiber, copper, coaxial)?

    • Answer: I have extensive experience with fiber optic cable (single-mode and multi-mode), copper twisted-pair cabling (various gauges and shielding), and coaxial cable (RG-6, RG-59). I understand their respective strengths and weaknesses, applications, installation techniques, testing methodologies, and troubleshooting procedures. I'm familiar with the latest standards and best practices for each type.

  2. Describe your experience with splicing fiber optic cable.

    • Answer: I'm proficient in fusion splicing and mechanical splicing techniques for fiber optic cable. I'm familiar with various splicing equipment and understand the importance of achieving low loss splices. My experience includes cleaning fibers, preparing fiber ends, aligning fibers for splicing, testing splice quality using an OTDR, and documenting splice locations and loss values.

  3. How do you troubleshoot a fiber optic cable cut?

    • Answer: I would use an OTDR (Optical Time-Domain Reflectometer) to pinpoint the location of the cut. Once located, I would then excavate the area to access the damaged section. After repairing the cable, I would perform a loss test to verify that the repair was successful and the signal is restored.

  4. Explain your understanding of OSP (Outside Plant) design principles.

    • Answer: OSP design involves considering factors such as cable routing, conduit sizing, splice closure placement, grounding, and protection from environmental factors (like water, rodents, and extreme temperatures). I understand the importance of adhering to industry standards and regulations (e.g., NEC) to ensure a reliable and safe network.

  5. What software are you familiar with for OSP design and documentation?

    • Answer: I'm proficient in [List specific software, e.g., AutoCAD, MicroStation, GIS software]. I also have experience using various cable management and documentation systems.

  6. How do you manage cable slack in OSP installations?

    • Answer: Proper slack management is crucial to prevent cable damage during temperature fluctuations and ground movement. I use appropriate slack loops and secure them properly within handholes or splice closures. The amount of slack is determined based on cable type, length, and environmental conditions.

  7. What are the safety precautions you take when working on OSP infrastructure?

    • Answer: Safety is paramount. I always follow safety regulations and company policies. This includes using appropriate personal protective equipment (PPE), like safety glasses, gloves, hard hats, and high-visibility clothing. I'm aware of potential hazards like underground utilities, traffic, and electrical lines, and I take necessary precautions to avoid them. I also ensure proper lockout/tagout procedures are followed when working near energized equipment.

  8. Describe your experience with different types of conduit.

    • Answer: I'm familiar with various conduit types, including PVC, HDPE, and metal conduit. I understand their properties, applications, and installation methods. I can select the appropriate conduit based on the environment, cable type, and project requirements.

  9. How do you test the continuity of a cable?

    • Answer: For copper cables, I use a cable tester or a multimeter to check for continuity and identify shorts or opens. For fiber optic cables, I use an OTDR to verify the continuity and measure the signal loss.
