Features of Coaxial Cable
Coaxial cable is a type of electrical cable consisting of an inner conductor surrounded by a tubular conducting shield, separated by an insulating material. This unique design offers several notable features:
Low Attenuation: The coaxial structure minimizes signal loss over long distances, making it suitable for high-frequency applications.
High Bandwidth: Coaxial cable can support a wide range of frequencies, allowing for high-speed data transmission and broadband internet access.
Low Crosstalk: The shielding effectively reduces electromagnetic interference between adjacent cables, ensuring signal integrity and preventing data corruption.
Durability: The rugged construction of coaxial cable provides resistance to moisture, chemicals, and mechanical stress, ensuring reliable performance in various environments.
Specifications of Coaxial Cable
Coaxial cables are characterized by various specifications that determine their performance and suitability for specific applications:
Characteristic Impedance: Measured in ohms, it represents the impedance of the cable over a specific frequency range. Typical values are 50 ohms and 75 ohms.
Velocity Factor: The ratio of the speed of an electromagnetic signal in the cable to the speed of light in a vacuum.
Attenuation: The reduction in signal strength per unit length of cable, typically expressed in decibels per 100 feet.
Shield Effectiveness: The ability of the shielding to prevent external electromagnetic interference, measured in decibels.
Applications of Coaxial Cable
Coaxial cable has a wide range of applications, including:
Telecommunications: Used for long-distance telephone and data transmission.
