Network Cables

 Network cables 

  •  Ethernet Cable (Cat5e/Cat6/Cat6a/Cat7): 

Purpose: Used for wired Ethernet networking in home and business environments. 

Categories: 

Cat5e: Supports up to 1 Gbps (Gigabit Ethernet) with a maximum frequency of 100 MHz 

Cat6: Supports up to 10 Gbps with a maximum frequency of 250 MHz

Cat6a: Enhanced Cat6, supports up to 10 Gbps with a higher maximum frequency of 500 MHz 

Cat7: Supports up to 10 Gbps with a maximum frequency of 600 MHz and offers shielding for reduced interference. 

  • Coaxial Cable: 

Purpose: Commonly used for cable television (CATV) and broadband internet connections. 

Construction: Consists of a copper or aluminum core surrounded by insulation, a metallic shield, and an outer insulating layer. 

Variants: RG-6 and RG-59 are common variants, with RG-6 being more suitable for high-bandwidth applications like HDTV and internet. 

Fiber Optic Cable: 

Purpose: Transmits data using light signals, providing high-speed and long-distance connectivity. 

Construction: Core made of glass or plastic fibers, surrounded by cladding and a protective outer layer. 

Types: 

Single-mode fiber: Ideal for long-distance communication, uses a single, narrow core. 

Multi-mode fiber: Suitable for shorter distances, uses multiple larger cores. 

  • Twisted Pair Cable: 

Purpose: Commonly used for telephone lines and networking. 

Construction: Consists of pairs of insulated copper wires twisted together to reduce electromagnetic interference. 

Categories: Unshielded Twisted Pair (UTP): Commonly used in Ethernet networks. 

Shielded Twisted Pair (STP): Provides additional shielding to reduce interference, often used in industrial environments. 

  • Power over Ethernet (PoE) Cable: 

Purpose: Enables the transmission of both data and electrical power over a single cable. 

Applications: Used in devices like IP cameras, VoIP phones, and other networked devices. 

Standards: IEEE 802.3af and IEEE 802.3at are common standards for PoE. 

  • USB Cable: 

Purpose: Primarily used for connecting peripherals and devices. 

Versions: USB 2.0, USB 3.0, USB 3.1, and USB-C are common variants, each offering different data transfer speeds and capabilities.
