Media & Connectors Flashcards
(20 cards)
What is the most common type of copper cabling in networking?
Twisted pair cabling (UTP and STP).
What does UTP stand for?
Unshielded Twisted Pair.
What does STP stand for?
Shielded Twisted Pair – has shielding to reduce EMI.
What is the purpose of twisted pair cabling?
To reduce electromagnetic interference (EMI) and crosstalk.
What is a coaxial cable used for?
Cable internet, older Ethernet networks, and TV signals.
What are the two main types of fiber optic cable?
Single-mode fiber and multi-mode fiber.
What is the difference between single-mode and multi-mode fiber?
Single-mode = long distances, uses laser; Multi-mode = shorter distances, uses LED.
What type of connector is commonly used with coaxial cable?
BNC connector.
What connector is used for Ethernet cables?
RJ-45 connector.
What connector is used for telephone cables?
RJ-11 connector.
What connector types are used with fiber optic cables?
ST, SC, LC, and MTRJ.
What does LC stand for (fiber connector)?
Lucent Connector – small form factor, common in modern fiber networks.
What does SC stand for (fiber connector)?
Subscriber Connector or Square Connector.
What is a plenum-rated cable?
Cable with special insulation for fire resistance in plenum spaces.
What is the maximum length for a Cat 5e or Cat 6 Ethernet cable?
100 meters (328 feet).
What is the difference between Cat 5e and Cat 6?
Cat 6 supports higher speeds and less crosstalk than Cat 5e.
What is the purpose of a media converter?
To convert signals between different media types (e.g., copper to fiber).
What is the purpose of a transceiver?
To send and receive data signals on a network.
Which type of cable is used in backbone connections for long distances?
Single-mode fiber.
What type of signal does fiber optic cable use?
Light signals.
