Cables Flashcards
Which of the following acronyms describes using a single twisted-pair Ethernet cable to carry both data and electrical power?
PoE (Power over ethernet)
A type of technology that enables sending data over wiring used for transmission of electrical power is known as:
PLC (Programmable logic controller)
What are characteristics of fiber-optic network cabling? [3]
- Immunity to electromagnetic interference
- More suitable for carrying digital information than copper cabling
- Used for network backbone cabling
What is the typical maximum segment length for a copper twisted-pair Ethernet cable?
100 Meters
What are characteristic features of Category 5 (Cat 5) cabling? [5]
- 100 Mbps Ethernet (100BaseT networks)
- 1 Gbps Ethernet (1000BaseT networks)
- 100-meter cable segment length
- RJ-45 connector
- Twisted-pair copper cabling
What is the common minimum requirement for twisted-pair copper cabling in modern Ethernet networks?
Cat 5e
Which of the following are characteristic features of Category 5e (Cat 5e) cabling? [5]
- 100 Mbps Ethernet (100BaseT networks)
- RJ-45 connector
- 100-meter cable segment length
- Twisted-pair copper cabling

What is the minimum cabling requirement needed to create a 10 Gbps Ethernet connection over copper twisted-pair cable?
Cat 6
In 10GBaseT networks, Category 6 (Cat 6) cabling supports a 10 Gbps data transfer rate at a limited range of 33-55 meters, whereas Cat 6A (Augmented) cabling allows for a 10 Gbps data transfer rate over a segment length of 100 meters. T/F
True
A special type of cabling with a fire-retardant jacket that is placed inside spaces between structural floors and dropped ceilings or inside of walls is known as plenum-rated cabling. T/F
True
Examples of copper cabling types used in Ethernet networks include: [3]
- STP
- UTP
- Coax
The main difference between UTP and STP cabling is that STP cables have additional protective covers that reduce signal interference from outside sources. T/F
True
What is UTP
Unshielded twisted pair
What are features of UTP cabling? [5]
- Twisted-pair copper cabling
- Used in Ethernet networks and telephone systems
- Low cost and ease of installation
- Not surrounded by any shielding that would provide protection against interference from outside sources
- In Ethernet networks, installed with RJ-45 connector type
What are copper cabling termination specifications? [2]
- T568A
- T568B
What type of Ethernet cable is used to establish a direct communication link between two PCs?

- Costs less than single-mode fiber optic cabling
- Uses LED as a source of light
What are the characteristics of single-mode fiber optic cabling? [3]
- Costs more than multimode fiber optics
- Transmits for distances of up to 100 km
- Uses laser as a source of light
What statements describe(s) coaxial cabling? [4]
- Used for carrying a cable television signal
- Copper cabling
