OSI layers are a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.
OSI stands for Open Systems Interconnection.
There are 7 layers in the OSI model: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the adjacent layers.
Example: The Physical layer deals with the...
TCP is connection-oriented, reliable, and slower. UDP is connectionless, unreliable, and faster.
TCP is connection-oriented, meaning a connection must be established before data can be transmitted.
TCP is reliable as it ensures all data packets are received in order and without errors.
TCP is slower compared to UDP due to the overhead of establishing and maintaining connections.
UDP is connectionless, meaning data can be s...
I applied via Company Website and was interviewed in Jan 2024. There were 2 interview rounds.
The person is productive for 7 hours.
The person works for 9 hours but takes a 1-hour break and 1-hour lunch.
Productive time is the time spent working without breaks or lunch.
Therefore, the person is productive for 7 hours.
An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal.
Types of optical amplifiers include erbium-doped fiber amplifiers (EDFAs), semiconductor optical amplifiers (SOAs), and Raman amplifiers.
Mux and demux are devices used in wavelength-division multiplexing (WDM) systems to combine and separate multiple optical signals on a single fiber.

OFC stands for Optical Fiber Cable, which is a type of cable made of glass or plastic fibers that transmit data using light.
OFC is used for high-speed data transmission over long distances.
It is commonly used in telecommunications, internet, and cable TV networks.
OFC is more reliable and has higher bandwidth than traditional copper cables.
Examples of OFC include single-mode fiber and multi-mode fiber.
OFC requires speci...
Multiplexer is a device that combines multiple signals into one signal. Demultiplexer is a device that separates one signal into multiple signals.
Multiplexer is also known as MUX.
It is used to increase the capacity of a communication channel.
Demultiplexer is also known as DEMUX.
It is used to route a single input signal to multiple output signals.
Multiplexer and demultiplexer are commonly used in digital communication s...
OTDR stands for Optical Time Domain Reflectometer. It is a device used to test and troubleshoot fiber optic networks.
OTDR sends a pulse of light into the fiber and measures the time and strength of the reflected signal.
It can detect faults such as breaks, bends, and splices in the fiber.
OTDR can also measure the length of the fiber and the attenuation of the signal.
It is an essential tool for maintaining and repairing ...
