1

Coaxial cable

Coax
Contains a center conductor made of copper. Surrounded by plastic jacket

2

Twisted Pair Cable

Multiple individually insulated wires twisted together
2 types. STP UTP

3

STP

Shielded twisted pair cables

4

UTP

Unshieded twisted pair cables.
10BaseT
100BaseTX
1000BaseTX

5

Plenum

Space between floors of multistory buildings.

6

Ethernet Cable Description

Describe with code: NX
Ex. 100BaseX
-the 100 tells us transmission speed is 100MB

7

Category 1

2 twisted wire pairs (4wires)
Referred as plain old telephone service (POTS)

8

Category 5

4 twisted wired pairs (8 wires)
Rates for 100 MHz

9

Category 6a

Augmented
Characterized to 500 MHz
Improve crosstalk characteristics
Allowed 10GBaseT to run for 100 meters

12

Fiber optic Cable

Immune to EMI and RFI
transmits digital signals using light pulses

13

Single Mode Fiber

SMF
spanning longer distance
Transmits data 50x further than multimode fiber at a faster rate

14

Multi mode Fiber

MMF
Used for shorter distance applications
Different # of light rays used

15

Fiber optic connectors

Straight tip (ST)
Subscriber (square) connector (SC)

16

Straight Tip

St
Uses BNC

17

Subscriber (square) connector

SC
Last for 1000 Mating

18

Small form factor fiber optic

(LC) Local connector

19

Universal Serial Bus

USB
Can connect a total of 127 external devices

20

Transmission speeds

In distribution and access areas, where users connect to switches
Typically 100Mbps per connection

21

Deciding factors of Cable choosing

Distance between components
Topology if a network

22

Crossover Cable

Connects like devices
Connects pins 1 to 3 and 2 to 6
Used in Ethernet UTP Installations

27

Straight through Cable

Connects unlike devices
