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

OTDR is used to test and troubleshoot fiber optic cables.
Connect OTDR to fiber optic cable and set parameters
Launch test and analyze results to locate faults or losses
Use OTDR to measure distance to faults or splices
Interpret OTDR trace to determine fiber characteristics
OTDR can also be used for fiber optic network mapping
PLB stands for Polyethylene Lined Steel Pipe.
PLB is a type of pipe used for underground fiber optic cables.
It consists of a steel pipe with a polyethylene lining.
The polyethylene lining protects the cable from moisture and other environmental factors.
PLB is commonly used in urban areas where space is limited and underground installation is necessary.
PLB is also known as HDPE (High-Density Polyethylene) pipe.
Measurement equipment used in fiber engineering include OTDR, power meter, light source, and visual fault locator.
OTDR (Optical Time Domain Reflectometer) measures the time and intensity of light reflected back from fiber optic cables.
Power meter measures the power of light transmitted through the fiber optic cable.
Light source generates light that is transmitted through the fiber optic cable to measure its attenuation...

Socket programming is a way to establish communication between two computers over a network using sockets.
It involves creating a socket, binding it to an IP address and port, listening for incoming connections, and sending/receiving data.
Examples of socket programming include creating a chat application, a file transfer program, or a web server.
IPv4 and IPv6 are internet protocol versions. IP masking is a technique to hide IP addresses.
IPv4 is the fourth version of the Internet Protocol, while IPv6 is the sixth version.
IPv4 uses 32-bit addresses, allowing for approximately 4.3 billion unique addresses.
IPv6 uses 128-bit addresses, providing a significantly larger address space.
IP masking, also known as IP anonymization, is the process of hiding the IP address ...
