3.1 Coaxial Cabling Flashcards
What is the structure of a coaxial cable?
Inner conductor, insulator, braided metal shield, and outer plastic jacket.
What are the two most common types of coaxial cables?
RG-6 and RG-59.
What is RG-6 primarily used for?
Outdoor connections and higher frequencies, like cable TV and internet.
What is RG-59 primarily used for?
Shorter distances, such as connecting cable modems or TVs.
What are the two common connectors used with coaxial cables?
F-Type and BNC.
What is an F-Type connector used for?
Consumer applications, such as cable TV and modems.
What is a BNC connector used for?
Legacy Ethernet networks, military applications, and older systems.
What is the main difference between coaxial and twinaxial cables?
Twinaxial cables have two inner conductors, while coaxial has one.
What are twinaxial cables typically used for?
High-speed, short-range connections, such as between switches in data centers.
What is the maximum speed of twinaxial cables?
Up to 10 Gbps.
What is the typical maximum distance for twinaxial cables?
Up to 7 meters.
Why are twinaxial cables considered cost-effective?
They provide high-speed connections over short distances without the cost of fiber.
What are the common applications of coaxial cables?
Cable TV, satellite systems, and legacy networks.
Why are BNC connectors still relevant today?
They are used in specific military and legacy systems for compatibility.
