Explain Network Cable Types Flashcards
Lesson 4C
The most popular type of network cable is of a copper wire construction of conducted copper wire 4 pairs that sends signals of either pair and less electrical interfernce under cabling of (328 ft max).
unshielded twisted pair (UTP).
provides extra protection against interference. often used for 10G Ethernet and higher within datacenter networks because it is more reliable than UTP
*(ScTP) or foiled/unshielded twisted pair (F/UTP)
*just foiled twisted pair (FTP)
*shielded/foiled twisted pair” (S/FTP)
*foil outer shield (F/FTP)
Shielded twisted pair (STP)
5 100 Mbps 100 m (328 ft) 100BASE-TX (Fast Ethernet)
5e 1 Gbps 100 m (328 ft) 1000BASE-T (GB Ethernet)
6 1 Gbps 100 m (328 ft) 1000BASE-T (GB Ethernet)
10 GBps 55 m (180 ft) 10GBASE-T (10 GB Ethernet)
6A 10 GBps 100 m (328 ft) 10GBASE-T (10 GB Ethernet)

Twisted Pair Cable
Cat specification is printed on the cable jacket along with the cable type (UTP
or F/UTP, for instance).
Twisted pair cabling for Ethernet can be terminated using modular and AKA “8P8C,” standing for eight-position/eightcontact.
Twisted pair RJ45 connectors
is typically used to terminate two-pair cable, which is widely used in telephone systems and with broadband digital subscriber line (DSL) modems.
RJ11 connectors
Permanent cable is terminated to wall ports and patch panels using insulation
displacement connectors (IDC)
punchdown blocks
To terminate cable, a small section of outer jacket must be removed to expose the wire pairs with a ?
Tool
cable (wire) stripper
is used to fix each conductor into an IDC in the appropriate termination order (T568A or T568B). To reduce the risk of interference, no more than ½” (13 mm) should be untwisted.

tester energizes each wire in turn, with an LED indicating successful termination. Otherwise, no signal caused by improper installation or damage wire.
Tool tester
cable tester
is used to identify a cable from within a bundle. This may be necessary when the cables have not been labeled properly.
Tool tester
toner probe
is used to test an NIC or switch port, you should see a solid link LED showing that the port can send and receive.
loopback plug
is used to intercept the signals passing over a cable and send them
to a packet or protocol analyzer.

* active TAP

Plenum space is typically a false ceiling, though it could also be constructed as a raised floor. As it makes installation simpler, this space has also been used for communications wiring in some building designs where building regulations require the use of fire-retardant plenum cable in such spaces.
Plenum Cable
Outside plant (OSP) is cable run on the external walls of a building or between two buildings. This makes the cable vulnerable to different types of weathering but this cable is limited to exposure… Which is laid and then covered in earth or cement/concrete.
cable
Direct burial
can support much higher bandwidth links, measured in multiple gigabits or terabits per second, and longer cable runs, measured in miles rather than feet with less interference.
optical cabling
- Single-mode fiber (SMF): long wavelength (1,310 or 1,550 nm) 10 Gbps or better and cable runs of many kilometers, depending on the quality
of the cable and optics - Multi-mode fiber (MMF): (62.5 or 50 microns) shorter wavelength infrared light (850 nm or 1,300 nm).
fiber optic
cable
is a different type of copper cabling, also carrying electrical signals and uses two conductors that share the same axis. is a different type of copper cabling, also carrying electrical signals.

Coaxial (coax) cable
