Media and Connectors

Question 1

Copper Media

1) A type of wiring in which two conductors of a single circuit are twisted together (The preferred method for transmitting both data and voice signals)

2) Consists of a single copper conductor at its core, with an insulating layer and a conductive shield covering

Answer 1

1) Twisted Pair Cable
I. UTP or STP
II. CAT 5
CAT 5e
CAT 6,
CAT 6a,
CAT 7,
CAT8
III. Plenum or Non-plenum

2) Coaxial (Coax) Cable
I. Standard (RG-6, RG-59)
DAC (Direct Attach Copper)
Twinaxial

Question 2

CAT coper twisted pair cables

Answer 2

CAT 5
100 Mbps - 100 meters
100 MHz frequency

CAT 5e
1000 Mbps/1 Gbps - 100 meters
100 MHz frequency

CAT 6
1 Gbps - 100 meters OR 10 Gbps - 55 meters
250 MHz frequency

CAT 6a
10 Gbps - 100 meters
500 MHz frequency

CAT 7
10 Gbps - 100 meters
600 MHz frequency

CAT 8
Up to 40 Gbps - 30 meters
2000 MHz/2 GHz frequency

Question 3

Copper Network Connectors

1) Standard connector for telephone wiring (PHONE network connector)

2) Standard connector for data networks that utilize copper cables to create ethernet network (DATA network connector)

3) Standard for cable television and satellite connections, and can also be used for cable Internet connections (Screw-on connector)

4) Another type of coaxial connector that is characterized by its secure bayonet locking mechanism (Push and twist connector)

Answer 3

1) RJ-11 connector
2) RJ-45 connector
3) F-type connector
4) BNC connector

Question 4

Straight-through cable vs. Crossover cable

Answer 4

Straight-through
DTE to DCE / DCE to DTE

Crossover
DTE to DTE / DCE to DCE

DTE are endpoint devices such as laptops, desktops, servers, and routers
DCE are switches, modems, hubs, and bridges

Question 5

Fiber Media

1) Used to transmit data using light instead of electrical impulses (EMI immunity, extended distances, 10-100 Gbps)

Types of Fiber Media

II. Designed for long-distance communication and features a small glass core typically around 8.3 to 10 microns in diameter (better for longer distances) (yellow colored sheath)

III. Tailored for shorter distances because it has a larger fiber core size that ranges from 50 to 100 microns (better for shorter distances and cheaper) (aqua blue or orange colored sheath)

Answer 5

1) Fiber Media

II. Single-Mode Fiber (SMF)

III. Multi-Mode Fiber (MMF)

Question 6

Fiber Network Connectors

1) Known for its square shape and push-pull design that offers a secure and simple connection mechanism (stick and click connecter)

2) Distinguished by a compact size that utilizes a push-pull mechanism similar to the SC, but in a much smaller form factor (love connector)

3) Recognizable by its round shape and twist-lock mechanism that offers a robust and reliable connector type for use in networks (stick and twist connector)

4) Features a small, rectangular design and houses both the transmit and receive fibers in a single connector

5) Designed to accommodate multiple fibers in a single connector to significantly increase that capacity and flexibility of the fiber networks

Answer 6

1) SC (Subscriber Connector)
2) LC (Lucent Connector)
3) ST (Straight Tip connector)
4) MTRJ (Mechanical Transfer-Registered Jack)
5) MPO (Multi-Fiber Push On)
