I appeared for an interview in Feb 2025, where I was asked the following questions.

  • Q1. What is the color code for optical fiber?
  • Ans. 

    Optical fiber color codes help identify individual fibers in a cable for proper termination and maintenance.

    • Standard color code for 12-fiber cables: Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose, Aqua.

    • Each color represents a specific fiber, aiding in organization and troubleshooting.

    • For example, in a 12-fiber cable, the first fiber is blue, the second is orange, and so on.

  • Answered by AI
  • Q2. What is network topology?
  • Ans. 

    Network topology refers to the arrangement of different elements in a computer network.

    • Types of topologies include star, ring, bus, and mesh.

    • In a star topology, all nodes connect to a central hub.

    • A ring topology connects each node to two others, forming a circular pathway.

    • Bus topology uses a single central cable to connect all devices.

    • Mesh topology allows for multiple paths between nodes, enhancing redundancy.

  • Answered by AI
  • Q3. What is ring topology?
  • Ans. 

    Ring topology is a network configuration where each device is connected in a circular fashion, forming a closed loop.

    • Data travels in one direction, reducing the chances of packet collisions.

    • If one device fails, it can disrupt the entire network unless a dual ring is used.

    • Commonly used in LANs and WANs, such as Token Ring networks.

    • Each device acts as a repeater, amplifying the signal for the next device.
