Telecommunications Subcategories

Signal Amplifiers

Boost signal strength to overcome attenuation during transmission

Multiplexers/Demultiplexers:

Combine multiple signals onto a single channel for transmission and separate them at the receiving end

Equalizers

Compensate for distortion and interference in the signal

Switches

Control the routing of data between different transmission paths

Modems (Modulators/Demodulators)

Convert digital data into analog signals for transmission and vice versa

Transmitters

Convert electronic signals into a form suitable for transmission over the communication channel

Receivers

Decode incoming signals into usable data

Protocols and Standards

Define rules and procedures for communication between devices and networks, ensuring compatibility and interoperability

Network Interface Cards (NICs)

Enable devices to connect to a network and communicate with each other

Error Detection and Correction Mechanisms

Identify and correct errors that occur during transmission

Transmission Media (Cables, Fiber Optics, Wireless)

Physical channels through which data is transmitted

Signal Regenerators

Reinforce and clean up signals to maintain their integrity over long distances

Why do we need the physical cables?

They may be connected to each other and to other system components via physical cables to facilitate power supply, control signals, synchronization, and data exchange. These cables serve to provide the necessary physical connections for the components to function as part of a coherent telecommunications system.
