Study Notes
UTP Cables and Standards
- Cat5e and Cat6 are the most commonly used UTP cables in modern networks.
- UTP cables are rated in categories including Cat1, Cat2, Cat3, Cat4, Cat5, Cat5e, and Cat6.
- Two standard wiring schemes for Ethernet cable termination are T568A and T568B.
Connectors
- RJ-45 connectors are used for Ethernet cables, suitable for modern networking.
- RJ-11 connectors are typically used for connecting desk phones and older devices.
- Roll-over cables use Serial DB9 on one end and RJ-45 on the other for console connections.
Types of Cables
- Twisted-pair cables (including UTP and STP) are the most common type of network cables due to their cost-effectiveness, ease of installation, and faster transmission rates.
- Coaxial cables are commonly used by ISPs for residential internet connectivity.
- Fiber optic cables are used for high-bandwidth networks, internet backbones, and telecommunications.
Cable Attributes
- Twisted-pair cables help minimize crosstalk and electromagnetic interference by twisting wires together in pairs.
- Unshielded twisted-pair (UTP) cables lack outer shielding, whereas shielded twisted-pair (STP) cables include a metallic shield for additional protection.
- Coaxial cables operate at Layer 1: The Physical Layer of the OSI model.
Cable Usage and Connection Types
- Straight-through cables connect unlike devices (e.g., computer to switch).
- Cross-over cables connect similar devices (e.g., PC to PC, switch to switch) and use different wiring on both ends.
- Twisted-pair cables are also used for console connections to network devices.
Distance and Performance
- Twisted-pair cables can support longer distances compared to some other cabling mediums.
- Coaxial cables, while used for high-frequency transmissions, are generally not used for long-distance networking compared to fiber optics.
Interference and Signal Transmission
- Twisting wires together reduces electromagnetic interference from external sources.
- The main purpose of coaxial cables is to carry high-frequency signals, often related to internet and television.
Cable Characteristics
- Distinctions between various cable types include:
- UTP for general networking,
- Coaxial for media connections, and
- Fiber optic for high-speed data transmission.
