Study Notes

Coaxial Cable

High-speed data transmission capability.
Enhanced shielding offers superior protection compared to twisted pair cables, leading to advanced bandwidth utilization.
More expensive than twisted pair cables.

Fiber Optic Cable

Entire network failure occurs with any fault in the cable.
Core consists of numerous light-transmitting materials like glass, plastic, or silica.
Core is surrounded by a protective shield to prevent intrusion.
Plastic coating safeguards optical fibers against electromagnetic interference, temperature extremes, and physical damage.

Advantages of Fiber Optic Cable

Provides significantly higher bandwidth with data transmitted in light form, enabling faster signal conveyance.
Effective for long-distance data transport.
Higher reliability due to resistance to temperature fluctuations.
Lightweight and thinner design allows for better stress resistance.
Less susceptible to noise interference.

Disadvantages of Fiber Optic Cable

Higher cost compared to other types of cables.
Requires regular and extensive maintenance.
Complex connectivity with other devices.
Fragility makes them prone to breakage.
Difficulty in installation due to delicate structure.

Unguided Media

Use of electromagnetic waves for signal transmission without physical connections, often referred to as wireless communication.

Radio Waves Transmission

Electromagnetic waves that propagate through open space in all directions, ranging from 3 kHz to 300 GHz.
Low frequency allows penetration through walls, facilitating signal reception indoors.
Common applications include FM radio, cordless phones, and television broadcasts.

Microwaves Transmission

Frequencies range from 1 GHz to 300 GHz, requiring a direct line of sight between devices for effective communication.
Used in various applications like radio navigation, point-to-point communications, satellite communications, and mobile phone communications.

Infrared Waves Transmission

Operate in the frequency range of 300 GHz to 400 THz, suitable for short-distance communication.
High frequency prevents penetration through walls.
Common uses include remote control devices, data transfer between mobile devices, and computer-to-phone data communication.
