Identifying Types Of Cables And Connectors Flashcards
Coaxial cable
Coax
Contains a center conductor made of copper. Surrounded by plastic jacket
Twisted Pair Cable
Multiple individually insulated wires twisted together
2 types. STP UTP
STP
Shielded twisted pair cables
UTP
Unshieded twisted pair cables.
10BaseT
100BaseTX
1000BaseTX
Plenum
Space between floors of multistory buildings.
Ethernet Cable Description
Describe with code: NX
Ex. 100BaseX
-the 100 tells us transmission speed is 100MB
Category 1
2 twisted wire pairs (4wires)
Referred as plain old telephone service (POTS)
Category 5
4 twisted wired pairs (8 wires)
Rates for 100 MHz
Category 6a
Augmented
Characterized to 500 MHz
Improve crosstalk characteristics
Allowed 10GBaseT to run for 100 meters
Connecting UTP
Used with UTP Cable
RJ-45
RJ-45
4 pairs (8 wires) White orange Orange White green Blue White blue Green White brown Brown
Fiber optic Cable
Immune to EMI and RFI
transmits digital signals using light pulses
Single Mode Fiber
SMF
spanning longer distance
Transmits data 50x further than multimode fiber at a faster rate
Multi mode Fiber
MMF
Used for shorter distance applications
Different # of light rays used
Fiber optic connectors
Straight tip (ST) Subscriber (square) connector (SC)
Straight Tip
St
Uses BNC
Subscriber (square) connector
SC
Last for 1000 Mating
Small form factor fiber optic
(LC) Local connector
Universal Serial Bus
USB
Can connect a total of 127 external devices
Transmission speeds
In distribution and access areas, where users connect to switches
Typically 100Mbps per connection
Deciding factors of Cable choosing
Distance between components
Topology if a network
Single mode Fiber to Ethernet
Convert signal from Ethernet and single mod
Accept Fiber and Ethernet connector

Crossover Cable
Connects like devices
Connects pins 1 to 3 and 2 to 6
Used in Ethernet UTP Installations
Straight through Cable
Connects unlike devices
